REST Resource: services.configs

Resource: Service

Service is the root object of Google service configuration schema. It describes basic information about a service, such as the name and the title, and delegates other aspects to sub-sections. Each sub-section is either a proto message or a repeated proto message that configures a specific aspect, such as auth. See each proto message definition for details.

Example:

type: google.api.Service
configVersion: 3
name: calendar.googleapis.com
title: Google Calendar API
apis:
- name: google.calendar.v3.Calendar
authentication:
  providers:
  - id: google_calendar_auth
    jwksUri: https://www.googleapis.com/oauth2/v1/certs
    issuer: https://securetoken.google.com
  rules:
  - selector: "*"
    requirements:
      providerId: google_calendar_auth

Fields
configVersion

integer

The semantic version of the service configuration. The config version affects the interpretation of the service configuration. For example, certain features are enabled by default for certain config versions.

The latest config version is 3.

name

string

The service name, which is a DNS-like logical identifier for the service, such as calendar.googleapis.com. The service name typically goes through DNS verification to make sure the owner of the service also owns the DNS name.

id

string

A unique ID for a specific instance of this message, typically assigned by the client for tracking purpose. Must be no longer than 63 characters and only lower case letters, digits, '.', '_' and '-' are allowed. If empty, the server may choose to generate one instead.

title

string

The product title for this service.

producerProjectId

string

The Google project that owns this service.

apis[]

object (Api)

A list of API interfaces exported by this service. Only the name field of the google.protobuf.Api needs to be provided by the configuration author, as the remaining fields will be derived from the IDL during the normalization process. It is an error to specify an API interface here which cannot be resolved against the associated IDL files.

types[]

object (Type)

A list of all proto message types included in this API service. Types referenced directly or indirectly by the apis are automatically included. Messages which are not referenced but shall be included, such as types used by the google.protobuf.Any type, should be listed here by name. Example:

types:
- name: google.protobuf.Int32
enums[]

object (Enum)

A list of all enum types included in this API service. Enums referenced directly or indirectly by the apis are automatically included. Enums which are not referenced but shall be included should be listed here by name. Example:

enums:
- name: google.someapi.v1.SomeEnum
documentation

object (Documentation)

Additional API documentation.

backend

object (Backend)

object (Endpoint)

Configuration for network endpoints. If this is empty, then an endpoint with the same name as the service is automatically generated to service all defined APIs.

control

object (Control)

Configuration for the service control plane.

logs[]

object (LogDescriptor)

Defines the logs used by this service.

metrics[]

object (MetricDescriptor)

Defines the metrics used by this service.

object (Billing)

Billing configuration.

logging

object (Logging)

Logging configuration.

monitoring

object (Monitoring)

Monitoring configuration.

systemParameters

object (SystemParameters)

System parameter configuration.

sourceInfo

object (SourceInfo)

Output only. The source information for this configuration if available.

systemTypes[]

object (Type)

A list of all proto message types included in this API service. It serves similar purpose as google.api.Service.types, except that these types are not needed by user-defined APIs. Therefore, they will not show up in the generated discovery doc. This field should only be used to define system APIs in ESF.

Api

Api is a light-weight descriptor for an API Interface.

Interfaces are also described as "protocol buffer services" in some contexts, such as by the "service" keyword in a .proto file, but they are different from API Services, which represent a concrete implementation of an interface as opposed to simply a description of methods and bindings. They are also sometimes simply referred to as "APIs" in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.

}
Fields
name

string

The fully qualified name of this interface, including package name followed by the interface's simple name.

methods[]

object (Method)

The methods of this interface, in unspecified order.

options[]

object (Option)

Any metadata attached to the interface.

version

string

A version string for this interface. If specified, must have the form major-version.minor-version, as in 1.10. If the minor version is omitted, it defaults to zero. If the entire version field is empty, the major version is derived from the package name, as outlined below. If the field is not empty, the version in the package name will be verified to be consistent with what is provided here.

The versioning schema uses semantic versioning where the major version number indicates a breaking change and the minor version an additive, non-breaking change. Both version numbers are signals to users what to expect from different versions, and should be carefully chosen based on the product plan.

The major version is also reflected in the package name of the interface, which must end in v<major-version>, as in google.feature.v1. For major versions 0 and 1, the suffix can be omitted. Zero major versions must only be used for experimental, non-GA interfaces.

sourceContext

object (SourceContext)

Source context for the protocol buffer service represented by this message.

mixins[]

object (Mixin)

Included interfaces. See Mixin.

syntax

enum (Syntax)

The source syntax of the service.

  "name": string,
  "requestTypeUrl": string,
  "requestStreaming": boolean,
  "responseTypeUrl": string,
  "responseStreaming": boolean,
  "options": [
    {

}
Fields
name

string

requestTypeUrl

string

A URL of the input message type.

requestStreaming

boolean

If true, the request is streamed.

responseTypeUrl

string

The URL of the output message type.

responseStreaming

boolean

If true, the response is streamed.

options[]

object (Option)

Any metadata attached to the method.

syntax

enum (Syntax)

The source syntax of this method.

Option

A protocol buffer option, which can be attached to a message, field, enumeration, etc.

JSON representation
{
  "name": string,
  "value": {
    "@type": string,
    field1: ...,
    ...
  }
}
Fields
name

string

The option's name. For protobuf built-in options (options defined in descriptor.proto), this is the short name. For example, "mapEntry". For custom options, it should be the fully-qualified name. For example, "google.api.http".

value

object

The option's value packed in an Any message. If the value is a primitive, the corresponding wrapper type defined in google/protobuf/wrappers.proto should be used. If the value is an enum, it should be stored as an int32 value using the google.protobuf.Int32Value type.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.

Syntax

The syntax in which a protocol buffer element is defined.

Enums
SYNTAX_PROTO2 Syntax proto2.
SYNTAX_PROTO3 Syntax proto3.

SourceContext

SourceContext represents information about the source of a protobuf element, like the file in which it is defined.

JSON representation
{
  "fileName": string
}
Fields
fileName

string

The path-qualified name of the .proto file that contained the associated protobuf element. For example: "google/protobuf/sourceContext.proto".

Mixin

Declares an API Interface to be included in this interface. The including interface must redeclare all the methods from the included interface, but documentation and options are inherited as follows:

  • If after comment and whitespace stripping, the documentation string of the redeclared method is empty, it will be inherited from the original method.

  • Each annotation belonging to the service config (http, visibility) which is not set in the redeclared method will be inherited.

  • If an http annotation is inherited, the path pattern will be modified as follows. Any version prefix will be replaced by the version of the including interface plus the root path if specified.

Example of a simple mixin:

package google.acl.v1;
service AccessControl {
  // Get the underlying ACL object.
  rpc GetAcl(GetAclRequest) returns (Acl) {
    option (google.api.http).get = "/v1/{resource=**}:getAcl";
  }
}

package google.storage.v2;
service Storage {
  //       rpc GetAcl(GetAclRequest) returns (Acl);

  // Get a data record.
  rpc GetData(GetDataRequest) returns (Data) {
    option (google.api.http).get = "/v2/{resource=**}";
  }
}

Example of a mixin configuration:

apis:
- name: google.storage.v2.Storage
  mixins:
  - name: google.acl.v1.AccessControl

The mixin construct implies that all methods in AccessControl are also declared with same name and request/response types in Storage. A documentation generator or annotation processor will see the effective Storage.GetAcl method after inherting documentation and annotations as follows:

service Storage {
  // Get the underlying ACL object.
  rpc GetAcl(GetAclRequest) returns (Acl) {
    option (google.api.http).get = "/v2/{resource=**}:getAcl";
  }
  ...
}

Note how the version in the path pattern changed from v1 to v2.

If the root field in the mixin is specified, it should be a relative path under which inherited HTTP paths are placed. Example:

apis:
- name: google.storage.v2.Storage
  mixins:
  - name: google.acl.v1.AccessControl
    root: acls

This implies the following inherited HTTP annotation:

service Storage {
  // Get the underlying ACL object.
  rpc GetAcl(GetAclRequest) returns (Acl) {
    option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";
  }
  ...
}

Documentation

Documentation provides the information for describing a service.

Example:

documentation:
  summary: >
    The Google Calendar API gives access
    to most calendar features.
  pages:
  - name: Overview
    content: (== include google/foo/overview.md ==)
  - name: Tutorial
    content: (== include google/foo/tutorial.md ==)
    subpages;
    - name: Java
      content: (== include google/foo/tutorial_java.md ==)
  rules:
  - selector: google.calendar.Calendar.Get
    description: >
      ...
  - selector: google.calendar.Calendar.Put
    description: >
      ...

Documentation is provided in markdown syntax. In addition to standard markdown features, definition lists, tables and fenced code blocks are supported. Section headers can be provided and are interpreted relative to the section nesting of the context where a documentation fragment is embedded.

Documentation from the IDL is merged with documentation defined via the config at normalization time, where documentation provided by config rules overrides IDL provided.

A number of constructs specific to the API platform are supported in documentation text.

In order to reference a proto element, the following notation can be used:

[fully.qualified.proto.name][]

To override the display text used for the link, this can be used:

[display text][fully.qualified.proto.name]

Text can be excluded from doc using the following notation:

(-- internal comment --)

A few directives are available in documentation. Note that directives must appear on a single line to be properly identified. The include directive includes a markdown file from an external source:

(== include path/to/file ==)

The resource_for directive marks a message to be the resource of a collection in REST view. If it is not specified, tools attempt to infer the resource from the operations in a collection:

(== resource_for v1.shelves.books ==)

The directive suppress_warning does not directly affect documentation and is documented together with service config validation.

JSON representation
{
  "summary": string,
  "pages": [
    {
      object (Page)
    }

    }
  ],
  "documentationRootUrl": string,
  "serviceRootUrl": string,
  "overview": string
}
Fields
summary

string

A short summary of what the service does. Can only be provided by plain text.

pages[]

object (Page)

The top level pages for the documentation set.

rules[]

object (DocumentationRule)

A list of documentation rules that apply to individual API elements.

NOTE: All service configuration rules follow "last one wins" order.

documentationRootUrl

string

The URL to the root of documentation.

serviceRootUrl

string

Specifies the service root url if the default one (the service name from the yaml file) is not suitable. This can be seen in any fully specified service urls as well as sections that show a base that other urls are relative to.

overview

string

Declares a single overview page. For example:

documentation:
  summary: ...
  overview: (== include overview.md ==)

This is a shortcut for the following declaration (using pages style):

documentation:
  summary: ...
  pages:
  - name: Overview
    content: (== include overview.md ==)

Note: you cannot specify both overview field and pages field.

Page

Represents a documentation page. A page can contain subpages to represent nested documentation set structure.

JSON representation
{
  "name": string,
  "content": string,
  "subpages": [
    {
      object (Page)
    }
  ]
}
Fields
name

string

The name of the page. It will be used as an identity of the page to generate URI of the page, text of the link to this page in navigation, etc. The full page name (start from the root page name to this page concatenated with .) can be used as reference to the page in your documentation. For example:

pages:
- name: Tutorial
  content: (== include tutorial.md ==)
  subpages:
  - name: Java
    content: (== include tutorial_java.md ==)

You can reference Java page using Markdown reference link syntax: [Java][Tutorial.Java].

content

string

The Markdown content of the page. You can use

(== include {path} ==)

to include content from a Markdown file.

subpages[]

object (Page)

Subpages of this page. The order of subpages specified here will be honored in the generated docset.

DocumentationRule

JSON representation
{
  "selector": string,
  "description": string,
  "deprecationDescription": string
}
Fields
selector

string

The selector is a comma-separated list of patterns. Each pattern is a qualified name of the element which may end in "*", indicating a wildcard. Wildcards are only allowed at the end and for a whole component of the qualified name, i.e. "foo.*" is ok, but not "foo.b*" or "foo.*.bar". A wildcard will match one or more components. To specify a default for all applicable elements, the whole pattern "*" is used.

description

string

description of the selected API(s).

deprecationDescription

string

Deprecation description of the selected element(s). It can be provided if an element is marked as deprecated.

Backend

Backend defines the backend configuration for a service.

JSON representation
{
  "rules": [
    {
      object (BackendRule)
    }
  ]
}
Fields
rules[]

object (BackendRule)

A list of API backend rules that apply to individual API methods.

NOTE: All service configuration rules follow "last one wins" order.

BackendRule

A backend rule provides configuration for an individual API element.

JSON representation
{
  "selector": string,
  "address": string,
  "deadline": number,
  "minDeadline": number,
  "operationDeadline": number,
  "pathTranslation": enum (PathTranslation),
  "protocol": string,

  // Union field authentication can be only one of the following:
  "jwtAudience": string,
  "disableAuth": boolean
  // End of list of possible types for union field authentication.
}
Fields
selector

string

Selects the methods to which this rule applies.

Refer to selector for syntax details.

address

string

The address of the API backend.

The scheme is used to determine the backend protocol and security. The following schemes are accepted:

SCHEME PROTOCOL SECURITY http:// HTTP None https:// HTTP TLS grpc:// gRPC None grpcs:// gRPC TLS

It is recommended to explicitly include a scheme. Leaving out the scheme may cause constrasting behaviors across platforms.

If the port is unspecified, the default is: - 80 for schemes without TLS - 443 for schemes with TLS

For HTTP backends, use protocol to specify the protocol version.

deadline

number

The number of seconds to wait for a response from a request. The default varies based on the request protocol and deployment environment.

minDeadline

number

Minimum deadline in seconds needed for this method. Calls having deadline value lower than this will be rejected.

operationDeadline

number

The number of seconds to wait for the completion of a long running operation. The default is no deadline.

pathTranslation

enum (PathTranslation)

protocol

string

The protocol used for sending a request to the backend. The supported values are "http/1.1" and "h2".

The default value is inferred from the scheme in the address field:

SCHEME PROTOCOL http:// http/1.1 https:// http/1.1 grpc:// h2 grpcs:// h2

For secure HTTP backends (https://) that support HTTP/2, set this field to "h2" for improved performance.

Configuring this field to non-default values is only supported for secure HTTP backends. This field will be ignored for all other backends.

See https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtml#alpn-protocol-ids for more details on the supported values.

Union field authentication. Authentication settings used by the backend.

These are typically used to provide service management functionality to a backend served on a publicly-routable URL. The authentication details should match the authentication behavior used by the backend.

For example, specifying jwt_audience implies that the backend expects authentication via a JWT.

When authentication is unspecified, the resulting behavior is the same as disable_auth set to true.

Refer to https://developers.google.com/identity/protocols/OpenIDConnect for JWT ID token. authentication can be only one of the following:

jwtAudience

string

The JWT audience is used when generating a JWT ID token for the backend. This ID token will be added in the HTTP "authorization" header, and sent to the backend.

disableAuth

boolean

When disableAuth is true, a JWT ID token won't be generated and the original "Authorization" HTTP header will be preserved. If the header is used to carry the original token and is expected by the backend, this field must be set to true to preserve the header.

PathTranslation

Path Translation specifies how to combine the backend address with the request path in order to produce the appropriate forwarding URL for the request.

Path Translation is applicable only to HTTP-based backends. Backends which do not accept requests over HTTP/HTTPS should leave pathTranslation unspecified.

Enums
PATH_TRANSLATION_UNSPECIFIED
CONSTANT_ADDRESS

Use the backend address as-is, with no modification to the path. If the URL pattern contains variables, the variable names and values will be appended to the query string. If a query string parameter and a URL pattern variable have the same name, this may result in duplicate keys in the query string.

Given the following operation config:

method path:        /api/company/{cid}/user/{uid}
Backend address:    https://example.cloudfunctions.net/getUser

Requests to the following request paths will call the backend at the translated path:

Request path: /api/company/widgetworks/user/johndoe
Translated:
https://example.cloudfunctions.net/getUser?cid=widgetworks&uid=johndoe

Request path: /api/company/widgetworks/user/johndoe?timezone=EST
Translated:
https://example.cloudfunctions.net/getUser?timezone=EST&cid=widgetworks&uid=johndoe
APPEND_PATH_TO_ADDRESS

The request path will be appended to the backend address.

Given the following operation config:

method path:        /api/company/{cid}/user/{uid}
Backend address:    https://example.appspot.com

Requests to the following request paths will call the backend at the translated path:

Request path: /api/company/widgetworks/user/johndoe
Translated:
https://example.appspot.com/api/company/widgetworks/user/johndoe

Request path: /api/company/widgetworks/user/johndoe?timezone=EST
Translated:
https://example.appspot.com/api/company/widgetworks/user/johndoe?timezone=EST

Http

Defines the HTTP configuration for an API service. It contains a list of HttpRule, each specifying the mapping of an RPC method to one or more HTTP REST API methods.

JSON representation
{
  "rules": [
    {
      object (HttpRule)
    }
  ],
  "fullyDecodeReservedExpansion": boolean
}
Fields
rules[]

object (HttpRule)

A list of HTTP configuration rules that apply to individual API methods.

NOTE: All service configuration rules follow "last one wins" order.

fullyDecodeReservedExpansion

boolean

When set to true, URL path parameters will be fully URI-decoded except in cases of single segment matches in reserved expansion, where "%2F" will be left encoded.

The default behavior is to not decode RFC 6570 reserved characters in multi segment matches.

HttpRule

gRPC Transcoding

gRPC Transcoding is a feature for mapping between a gRPC method and one or more HTTP REST endpoints. It allows developers to build a single API service that supports both gRPC APIs and REST APIs. Many systems, including Google APIs, Cloud Endpoints, gRPC Gateway, and Envoy proxy support this feature and use it for large scale production services.

HttpRule defines the schema of the gRPC/REST mapping. The mapping specifies how different portions of the gRPC request message are mapped to the URL path, URL query parameters, and HTTP request body. It also controls how the gRPC response message is mapped to the HTTP response body. HttpRule is typically specified as an google.api.http annotation on the gRPC method.

Each mapping specifies a URL path template and an HTTP method. The path template may refer to one or more fields in the gRPC request message, as long as each field is a non-repeated field with a primitive (non-message) type. The path template controls how fields of the request message are mapped to the URL path.

Example:

service Messaging {
  rpc GetMessage(GetMessageRequest) returns (Message) {
    option (google.api.http) = {
        get: "/v1/{name=messages/*}"
    };
  }
}
message GetMessageRequest {
  string name = 1; // Mapped to URL path.
}
message Message {
  string text = 1; // The resource content.
}

This enables an HTTP REST to gRPC mapping as below:

HTTP gRPC
GET /v1/messages/123456 GetMessage(name: "messages/123456")

Any fields in the request message which are not bound by the path template automatically become HTTP query parameters if there is no HTTP request body. For example:

service Messaging {
  rpc GetMessage(GetMessageRequest) returns (Message) {
    option (google.api.http) = {
        get:"/v1/messages/{message_id}"
    };
  }
}
message GetMessageRequest {
  message SubMessage {
    string subfield = 1;
  }
  string message_id = 1; // Mapped to URL path.
  int64 revision = 2;    // Mapped to URL query parameter `revision`.
  SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
}

This enables a HTTP JSON to RPC mapping as below:

HTTP gRPC
GET /v1/messages/123456?revision=2&sub.subfield=foo

GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))

Note that fields which are mapped to URL query parameters must have a primitive type or a repeated primitive type or a non-repeated message type. In the case of a repeated type, the parameter can be repeated in the URL as ...?param=A&param=B. In the case of a message type, each field of the message is mapped to a separate parameter, such as ...?foo.a=A&foo.b=B&foo.c=C.

For HTTP methods that allow a request body, the body field specifies the mapping. Consider a REST update method on the message resource collection:

service Messaging {
  rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
    option (google.api.http) = {
      patch: "/v1/messages/{message_id}"
      body: "message"
    };
  }
}
message UpdateMessageRequest {
  string message_id = 1; // mapped to the URL
  Message message = 2;   // mapped to the body
}

The following HTTP JSON to RPC mapping is enabled, where the representation of the JSON in the request body is determined by protos JSON encoding:

HTTP gRPC
PATCH /v1/messages/123456 { "text": "Hi!" } UpdateMessage(message_id: "123456" message { text: "Hi!" })

The special name * can be used in the body mapping to define that every field not bound by the path template should be mapped to the request body. This enables the following alternative definition of the update method:

service Messaging {
  rpc UpdateMessage(Message) returns (Message) {
    option (google.api.http) = {
      patch: "/v1/messages/{message_id}"
      body: "*"
    };
  }
}
message Message {
  string message_id = 1;
  string text = 2;
}

The following HTTP JSON to RPC mapping is enabled:

HTTP gRPC
PATCH /v1/messages/123456 { "text": "Hi!" } UpdateMessage(message_id: "123456" text: "Hi!")

Note that when using * in the body mapping, it is not possible to have HTTP parameters, as all fields not bound by the path end in the body. This makes this option more rarely used in practice when defining REST APIs. The common usage of * is in custom methods which don't use the URL at all for transferring data.

It is possible to define multiple HTTP methods for one RPC by using the additionalBindings option. Example:

service Messaging {
  rpc GetMessage(GetMessageRequest) returns (Message) {
    option (google.api.http) = {
      get: "/v1/messages/{message_id}"
      additionalBindings {
        get: "/v1/users/{userId}/messages/{message_id}"
      }
    };
  }
}
message GetMessageRequest {
  string message_id = 1;
  string userId = 2;
}

This enables the following two alternative HTTP JSON to RPC mappings:

HTTP gRPC
GET /v1/messages/123456 GetMessage(message_id: "123456")
GET /v1/users/me/messages/123456 GetMessage(userId: "me" message_id: "123456")
Rules for HTTP mapping
  1. Leaf request fields (recursive expansion nested messages in the request message) are classified into three categories:
  • Fields referred by the path template. They are passed via the URL path.
  • Fields referred by the HttpRule.body. They are passed via the HTTP request body.
  • All other fields are passed via the URL query parameters, and the parameter name is the field path in the request message. A repeated field can be represented as multiple query parameters under the same name.
  1. If HttpRule.body is "*", there is no URL query parameter, all fields are passed via URL path and HTTP request body.
  2. If HttpRule.body is omitted, there is no HTTP request body, all fields are passed via URL path and URL query parameters.
Path template syntax
Template = "/" Segments [ Verb ] ;
Segments = Segment { "/" Segment } ;
Segment  = "*" | "**" | LITERAL | Variable ;
Variable = "{" FieldPath [ "=" Segments ] "}" ;
FieldPath = IDENT { "." IDENT } ;
Verb     = ":" LITERAL ;

The syntax * matches a single URL path segment. The syntax ** matches zero or more URL path segments, which must be the last part of the URL path except the Verb.

The syntax Variable matches part of the URL path as specified by its template. A variable template must not contain other variables. If a variable matches a single path segment, its template may be omitted, e.g. {var} is equivalent to {var=*}.

The syntax LITERAL matches literal text in the URL path. If the LITERAL contains any reserved character, such characters should be percent-encoded before the matching.

If a variable contains exactly one path segment, such as "{var}" or "{var=*}", when such a variable is expanded into a URL path on the client side, all characters except [-_.~0-9a-zA-Z] are percent-encoded. The server side does the reverse decoding. Such variables show up in the Discovery Document as {var}.

If a variable contains multiple path segments, such as "{var=foo/*}" or "{var=**}", when such a variable is expanded into a URL path on the client side, all characters except [-_.~/0-9a-zA-Z] are percent-encoded. The server side does the reverse decoding, except "%2F" and "%2f" are left unchanged. Such variables show up in the Discovery Document as {+var}.

Using gRPC API Service Configuration

gRPC API Service Configuration (service config) is a configuration language for configuring a gRPC service to become a user-facing product. The service config is simply the YAML representation of the google.api.Service proto message.

As an alternative to annotating your proto file, you can configure gRPC transcoding in your service config YAML files. You do this by specifying a HttpRule that maps the gRPC method to a REST endpoint, achieving the same effect as the proto annotation. This can be particularly useful if you have a proto that is reused in multiple services. Note that any transcoding specified in the service config will override any matching transcoding configuration in the proto.

Example:

http:
  rules:
    # Selects a gRPC method and applies HttpRule to it.
    - selector: example.v1.Messaging.GetMessage
      get: /v1/messages/{message_id}/{sub.subfield}
Special notes

When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the proto to JSON conversion must follow the proto3 specification.

While the single segment variable follows the semantics of RFC 6570 Section 3.2.2 Simple String Expansion, the multi segment variable does not follow RFC 6570 Section 3.2.3 reserved Expansion. The reason is that the reserved Expansion does not expand special characters like ? and #, which would lead to invalid URLs. As the result, gRPC Transcoding uses a custom encoding for multi segment variables.

The path variables must not refer to any repeated or mapped field, because client libraries are not capable of handling such variable expansion.

The path variables must not capture the leading "/" character. The reason is that the most common use case "{var}" does not capture the leading "/" character. For consistency, all path variables must share the same behavior.

Repeated message fields must not be mapped to URL query parameters, because no client library can support such complicated mapping.

If an API needs to use a JSON array for request or response body, it can map the request or response body to a repeated field. However, some gRPC Transcoding implementations may not support this feature.

Quota

Quota configuration helps to achieve fairness and budgeting in service usage.

The metric based quota configuration works this way: - The service configuration defines a set of metrics. - For API calls, the quota.metric_rules maps methods to metrics with corresponding costs. - The quota.limits defines limits on the metrics, which will be used for quota checks at runtime.

An example quota configuration in yaml format:

quota: limits:

 - name: apiWriteQpsPerProject
   metric: library.googleapis.com/write_calls
   unit: "1/min/{project}"  # rate limit for consumer projects
   values:
     STANDARD: 10000


 # The metric rules bind all methods to the read_calls metric,
 # except for the UpdateBook and DeleteBook methods. These two methods
 # are mapped to the write_calls metric, with the UpdateBook method
 # consuming at twice rate as the DeleteBook method.
 metricRules:
 - selector: "*"
   metricCosts:
     library.googleapis.com/read_calls: 1
 - selector: google.example.library.v1.LibraryService.UpdateBook
   metricCosts:
     library.googleapis.com/write_calls: 2
 - selector: google.example.library.v1.LibraryService.DeleteBook
   metricCosts:
     library.googleapis.com/write_calls: 1

Corresponding Metric definition:

  "metric": string,
  "unit": string,
  "values": {
    string: string,
    ...
  },
  "displayName": string
}
Fields
name

string

name of the quota limit.

The name must be provided, and it must be unique within the service. The name can only include alphanumeric characters as well as '-'.

The maximum length of the limit name is 64 characters.

description

string

Optional. User-visible, extended description for this quota limit. Should be used only when more context is needed to understand this limit than provided by the limit's display name (see: displayName).

defaultLimit

string (int64 format)

Default number of tokens that can be consumed during the specified duration. This is the number of tokens assigned when a client application developer activates the service for his/her project.

Specifying a value of 0 will block all requests. This can be used if you are provisioning quota to selected consumers and blocking others. Similarly, a value of -1 will indicate an unlimited quota. No other negative values are allowed.

Used by group-based quotas only.

maxLimit

string (int64 format)

Maximum number of tokens that can be consumed during the specified duration. Client application developers can override the default limit up to this maximum. If specified, this value cannot be set to a value less than the default limit. If not specified, it is set to the default limit.

To allow clients to apply overrides with no upper bound, set this to -1, indicating unlimited maximum quota.

Used by group-based quotas only.

freeTier

string (int64 format)

Free tier value displayed in the Developers Console for this limit. The free tier is the number of tokens that will be subtracted from the billed amount when billing is enabled. This field can only be set on a limit with duration "1d", in a billable group; it is invalid on any other limit. If this field is not set, it defaults to 0, indicating that there is no free tier for this service.

Used by group-based quotas only.

duration

string

Duration of this limit in textual notation. Must be "100s" or "1d".

Used by group-based quotas only.

metric

string

The name of the metric this quota limit applies to. The quota limits with the same metric will be checked together during runtime. The metric must be defined within the service config.

unit

string

Specify the unit of the quota limit. It uses the same syntax as [Metric.unit][]. The supported unit kinds are determined by the quota backend system.

Here are some examples: * "1/min/{project}" for quota per minute per project.

Note: the order of unit components is insignificant. The "1" at the beginning is required to follow the metric unit syntax.

values

map (key: string, value: string (int64 format))

Tiered limit values. You must specify this as a key:value pair, with an integer value that is the maximum number of requests allowed for the specified unit. Currently only STANDARD is supported.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

displayName

string

User-visible display name for this limit. Optional. If not set, the UI will provide a default display name based on the quota configuration. This field can be used to override the default display name generated from the configuration.

MetricRule

Bind API methods to metrics. Binding a method to a metric causes that metric's configured quota behaviors to apply to the method call.

JSON representation
{
  "selector": string,
  "metricCosts": {
    string: string,
    ...
  }
}
Fields
selector

string

Selects the methods to which this rule applies.

Refer to selector for syntax details.

metricCosts

map (key: string, value: string (int64 format))

Metrics to update when the selected methods are called, and the associated cost applied to each metric.

The key of the map is the metric name, and the values are the amount increased for the metric against which the quota limits are defined. The value must not be negative.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

Authentication

Authentication defines the authentication configuration for an API.

Example for an API targeted for external use:

AuthenticationRule

Authentication rules for the service.

By default, if a method has any authentication requirements, every request must include a valid credential matching one of the requirements. It's an error to include more than one kind of credential in a single request.

If a method doesn't have any auth requirements, request credentials will be ignored.

JSON representation

oauth

object (OAuthRequirements)

The requirements for OAuth credentials.

allowWithoutCredential

boolean

If true, the service accepts API keys without any other credential.

requirements[]

object (AuthRequirement)

Requirements for additional authentication providers.

OAuthRequirements

OAuth scopes are a way to define data and permissions on data. For example, there are scopes defined for "Read-only access to Google Calendar" and "Access to Cloud Platform". Users can consent to a scope for an application, giving it permission to access that data on their behalf.

OAuth scope specifications should be fairly coarse grained; a user will need to see and understand the text description of what your scope means.

In most cases: use one or at most two OAuth scopes for an entire family of products. If your product has multiple APIs, you should probably be sharing the OAuth scope across all of those APIs.

When you need finer grained OAuth consent screens: talk with your product management about how developers will use them in practice.

Please note that even though each of the canonical scopes is enough for a request to be accepted and passed to the backend, a request can still fail due to the backend requiring additional scopes or permissions.

JSON representation
{
  "canonicalScopes": string
}
Fields
canonicalScopes

string

The list of publicly documented OAuth scopes that are allowed access. An OAuth token containing any of these scopes will be accepted.

Example:

 canonicalScopes: https://www.googleapis.com/auth/calendar,
                   https://www.googleapis.com/auth/calendar.read

AuthRequirement

User-defined authentication requirements, including support for JSON Web token (JWT).

JSON representation
{
  "providerId": string,
  "audiences": string

string

id from authentication provider.

Example:

providerId: bookstore_auth
audiences

string

NOTE: This will be deprecated soon, once AuthProvider.audiences is implemented and accepted in all the runtime components.

The list of JWT audiences. that are allowed to access. A JWT containing any of these audiences will be accepted. When this setting is absent, only JWTs with audience "https://Service_name/API_name" will be accepted. For example, if no audiences are in the setting, LibraryService API will only accept JWTs with the following audience "https://library-example.googleapis.com/google.example.library.v1.LibraryService".

Example:

audiences: bookstore_android.apps.googleusercontent.com,
           bookstore_web.apps.googleusercontent.com

  ]
}
Fields
id

string

The unique identifier of the auth provider. It will be referred to by AuthRequirement.provider_id.

Example: https://securetoken.google.com Example: 1234567-compute@developer.gserviceaccount.com

jwksUri

string

URL of the provider's public key set to validate signature of the JWT. See OpenID Discovery. Optional if the key set document: - can be retrieved from [OpenID Discovery](https://openid.net/specs/openid-connect-discovery-1_0.html of the issuer. - can be inferred from the email domain of the issuer (e.g. a Google service account).

Example: https://www.googleapis.com/oauth2/v1/certs

audiences

string

The list of JWT audiences. that are allowed to access. A JWT containing any of these audiences will be accepted. When this setting is absent, JWTs with audiences: - "https://[service.name]/google.protobuf.Api.name" - "https://[service.name]/" will be accepted. For example, if no audiences are in the setting, LibraryService API will accept JWTs with the following audiences: - https://library-example.googleapis.com/google.example.library.v1.LibraryService - https://library-example.googleapis.com/

Example:

audiences: bookstore_android.apps.googleusercontent.com,
           bookstore_web.apps.googleusercontent.com

Defines the locations to extract the JWT.

JWT locations can be either from HTTP headers or URL query parameters. The rule is that the first match wins. The checking order is: checking all headers first, then URL query parameters.

If not specified, default to use following 3 locations: 1) Authorization: Bearer 2) x-goog-iap-jwt-assertion 3) access_token query parameter

Default locations can be specified as followings: jwtLocations: - header: Authorization valuePrefix: "Bearer " - header: x-goog-iap-jwt-assertion - query: access_token

JwtLocation

Specifies a location to extract JWT from an API request.

JSON representation
{
  "valuePrefix": string,

  // Union field in can be only one of the following:
  "header": string,
  "query": string
  // End of list of possible types for union field in.
}
Fields
valuePrefix

string

The value prefix. The value format is "valuePrefix{token}" Only applies to "in" header type. Must be empty for "in" query type. If not empty, the header value has to match (case sensitive) this prefix. If not matched, JWT will not be extracted. If matched, JWT will be extracted after the prefix is removed.

For example, for "Authorization: Bearer {JWT}", valuePrefix="Bearer " with a space at the end.

Union field in.

in can be only one of the following:

header

string

Specifies HTTP header name to extract JWT token.

query

string

Specifies URL query parameter name to extract JWT token.

Context

Context defines which contexts an API requests.

Example:

context:
  rules:
  - selector: "*"
    requested:
    - google.rpc.context.ProjectContext
    - google.rpc.context.OriginContext

The above specifies that all methods in the API request google.rpc.context.ProjectContext and google.rpc.context.OriginContext.

Available context types are defined in package google.rpc.context.

This also provides mechanism to whitelist any protobuf message extension that can be sent in grpc metadata using “x-goog-ext--bin” and “x-goog-ext--jspb” format. For example, list any service specific protobuf types that can appear in grpc metadata as follows in your yaml file:

Example:

context:
  rules:
   - selector: "google.example.library.v1.LibraryService.CreateBook"
     allowedRequestExtensions:
     - google.foo.v1.NewExtension
     allowedResponseExtensions:
     - google.foo.v1.NewExtension

You can also specify extension ID instead of fully qualified extension name here.

Endpoint

Endpoint describes a network endpoint that serves a set of APIs. A service may expose any number of endpoints, and all endpoints share the same service configuration, such as quota configuration and monitoring configuration.

Example service configuration:

name: library-example.googleapis.com
endpoints:
  # Below entry makes 'google.example.library.v1.Library'
  # API be served from endpoint address library-example.googleapis.com.
  # It also allows HTTP OPTIONS calls to be passed to the backend, for
  # it to decide whether the subsequent cross-origin request is
  # allowed to proceed.
- name: library-example.googleapis.com
  allowCors: true
JSON representation
{
  "name": string,
  "aliases": [
    string
  ],
  "target": string,
  "allowCors": boolean
}
Fields
name

string

The canonical name of this endpoint.

    description: Identifier of a library customer
JSON representation
{
  "name": string,
  "labels": [
    {
      object (LabelDescriptor)
    }
  ],
  "description": string,

LabelDescriptor

A description of a label.

JSON representation
{
  "key": string,
  "valueType": enum (ValueType),
  "description": string
}
Fields
key

string

The label key.

valueType

enum (ValueType)

The type of data that can be assigned to the label.

ValueType

Value types that can be used as label values.

Enums
STRING A variable-length string. This is the default.
BOOL Boolean; true or false.
INT64 A 64-bit signed integer.

MetricDescriptor

Defines a metric type and its schema. Once a metric descriptor is created, deleting or altering it stops data collection and makes the metric type's existing data unusable.

The following are specific rules for service defined Monitoring metric descriptors:

  • type, metricKind, valueType, description, displayName, launchStage fields are all required. The unit field must be specified if the valueType is any of DOUBLE, INT64, DISTRIBUTION.
  • Maximum of default 500 metric descriptors per service is allowed.
  • Maximum of default 10 labels per metric descriptor is allowed.

The default maximum limit can be overridden. Please follow https://cloud.google.com/monitoring/quotas

JSON representation
{
  "name": string,
  "type": string,
  "labels": [
    {
      object (LabelDescriptor)
    }
  ],
  "metricKind": enum (MetricKind),
  "valueType": enum (ValueType),

  "description": string,
  "displayName": string,
  "metadata": {
    object (MetricDescriptorMetadata)
  },
  "launchStage": enum (LaunchStage),
  "monitoredResourceTypes": [
    string
  ]
}
Fields
name

string

The resource name of the metric descriptor.

type

string

The metric type, including its DNS name prefix. The type is not URL-encoded.

All service defined metrics must be prefixed with the service name, in the format of {service name}/{relative metric name}, such as cloudsql.googleapis.com/database/cpu/utilization. The relative metric name must follow:

  • Only upper and lower-case letters, digits, '/' and underscores '_' are allowed.
  • The maximum number of characters allowed for the relative_metric_name is 100.

All user-defined metric types have the DNS name custom.googleapis.com, external.googleapis.com, or logging.googleapis.com/user/.

Metric types should use a natural hierarchical grouping. For example:

"custom.googleapis.com/invoice/paid/amount"
"external.googleapis.com/prometheus/up"
"appengine.googleapis.com/http/server/response_latencies"
labels[]

object (LabelDescriptor)

The set of labels that can be used to describe a specific instance of this metric type.

The label key name must follow:

  • Only upper and lower-case letters, digits and underscores (_) are allowed.
  • Label name must start with a letter or digit.
  • The maximum length of a label name is 100 characters.

For example, the appengine.googleapis.com/http/server/response_latencies metric type has a label for the HTTP response code, response_code, so you can look at latencies for successful responses or just for responses that failed.

metricKind

enum (MetricKind)

Whether the metric records instantaneous values, changes to a value, etc. Some combinations of metricKind and valueType might not be supported.

valueType

enum (ValueType)

Whether the measurement is an integer, a floating-point number, etc. Some combinations of metricKind and valueType might not be supported.

unit

string

The units in which the metric value is reported. It is only applicable if the valueType is INT64, DOUBLE, or DISTRIBUTION. The unit defines the representation of the stored metric values.

Different systems may scale the values to be more easily displayed (so a value of 0.02KBy might be displayed as 20By, and a value of 3523KBy might be displayed as 3.5MBy). However, if the unit is KBy, then the value of the metric is always in thousands of bytes, no matter how it may be displayed..

If you want a custom metric to record the exact number of CPU-seconds used by a job, you can create an INT64 CUMULATIVE metric whose unit is s{CPU} (or equivalently 1s{CPU} or just s). If the job uses 12,005 CPU-seconds, then the value is written as 12005.

Alternatively, if you want a custom metric to record data in a more granular way, you can create a DOUBLE CUMULATIVE metric whose unit is ks{CPU}, and then write the value 12.005 (which is 12005/1000), or use Kis{CPU} and write 11.723 (which is 12005/1024).

The supported units are a subset of The Unified Code for Units of Measure standard:

Basic units (UNIT)

  • bit bit
  • By byte
  • s second
  • min minute
  • h hour
  • d day
  • 1 dimensionless

Prefixes (PREFIX)

  • k kilo (10^3)
  • M mega (10^6)
  • G giga (10^9)
  • T tera (10^12)
  • P peta (10^15)
  • E exa (10^18)
  • Z zetta (10^21)
  • Y yotta (10^24)
  • m milli (10^-3)

  • u micro (10^-6)
  • n nano (10^-9)
  • p pico (10^-12)
  • f femto (10^-15)
  • a atto (10^-18)
  • z zepto (10^-21)
  • y yocto (10^-24)
  • Ki kibi (2^10)

  • Mi mebi (2^20)
  • Gi gibi (2^30)
  • Ti tebi (2^40)
  • Pi pebi (2^50)

Grammar

The grammar also includes these connectors:

  • / division or ratio (as an infix operator). For examples, kBy/{email} or MiBy/10ms (although you should almost never have /s in a metric unit; rates should always be computed at query time from the underlying cumulative or delta value).
  • . multiplication or composition (as an infix operator). For examples, GBy.d or k{watt}.h.

The grammar for a unit is as follows:

Expression = Component { "." Component } { "/" Component } ;

Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ]
          | Annotation
          | "1"
          ;

Annotation = "{" NAME "}" ;

Notes:

  • Annotation is just a comment if it follows a UNIT. If the annotation is used alone, then the unit is equivalent to 1. For examples, {request}/s == 1/s, By{transmitted}/s == By/s.
  • NAME is a sequence of non-blank printable ASCII characters not containing { or }.
  • 1 represents a unitary dimensionless unit of 1, such as in 1/s. It is typically used when none of the basic units are appropriate. For example, "new users per day" can be represented as 1/d or {new-users}/d (and a metric value 5 would mean "5 new users). Alternatively, "thousands of page views per day" would be represented as 1000/d or k1/d or k{page_views}/d (and a metric value of 5.3 would mean "5300 page views per day").
  • % represents dimensionless value of 1/100, and annotates values giving a percentage (so the metric values are typically in the range of 0..100, and a metric value 3 means "3 percent").
  • 10^2.% indicates a metric contains a ratio, typically in the range 0..1, that will be multiplied by 100 and displayed as a percentage (so a metric value 0.03 means "3 percent").

Enums
METRIC_KIND_UNSPECIFIED Do not use this default value.
GAUGE An instantaneous measurement of a value.
DELTA The change in a value during a time interval.

}
Fields
launchStage
(deprecated)

enum (LaunchStage)

Deprecated. Must use the MetricDescriptor.launch_stage instead.

samplePeriod

string (Duration format)

The sampling period of metric data points. For metrics which are written periodically, consecutive data points are stored at this time interval, excluding data loss due to errors. Metrics with a higher granularity have a smaller sampling period.

A duration in seconds with up to nine fractional digits, terminated by 's'. Example: "3.5s".

ingestDelay

string (Duration format)

The delay of data points caused by ingestion. Data points older than this age are guaranteed to be ingested and available to be read, excluding data loss due to errors.

A duration in seconds with up to nine fractional digits, terminated by 's'. Example: "3.5s".

UNIMPLEMENTED The feature is not yet implemented. Users can not use it.
PRELAUNCH Prelaunch features are hidden from users and are only visible internally.
EARLY_ACCESS Early Access features are limited to a closed group of testers. To use these features, you must sign up in advance and sign a Trusted Tester agreement (which includes confidentiality provisions). These features may be unstable, changed in backward-incompatible ways, and are not guaranteed to be released.
ALPHA Alpha is a limited availability test for releases before they are cleared for widespread use. By Alpha, all significant design issues are resolved and we are in the process of verifying functionality. Alpha customers need to apply for access, agree to applicable terms, and have their projects whitelisted. Alpha releases don’t have to be feature complete, no SLAs are provided, and there are no technical support obligations, but they will be far enough along that customers can actually use them in test environments or for limited-use tests -- just like they would in normal production cases.
BETA Beta is the point at which we are ready to open a release for any customer to use. There are no SLA or technical support obligations in a Beta release. Products will be complete from a feature perspective, but may have some open outstanding issues. Beta releases are suitable for limited production use cases.
GA GA features are open to all developers and are considered stable and fully qualified for production use.
DEPRECATED Deprecated features are scheduled to be shut down and removed. For more information, see the “Deprecation Policy” section of our Terms of Service and the Google Cloud Platform Subject to the Deprecation Policy documentation.

MonitoredResourceDescriptor

For example, the monitored resource descriptor for Google Compute Engine VM instances has a type of "gce_instance" and specifies the use of the labels "instance_id" and "zone" to identify particular VM instances.

Different services can support different monitored resource types.

The following are specific rules to service defined monitored resources for Monitoring and Logging:

  • The type, displayName, description, labels and launchStage fields are all required.
  • The first label of the monitored resource descriptor must be resourceContainer. There are legacy monitored resource descritptors start with projectId.
  • It must include a location label.
  • Maximum of default 5 service defined monitored resource descriptors is allowed per service.
  • Maximum of default 10 labels per monitored resource is allowed.

The default maximum limit can be overridden. Please follow https://cloud.google.com/monitoring/quotas

    {
      object (SystemParameterRule)
    }
  ]
}
Fields
rules[]

The parameters defined here will override the default parameters implemented by the system. If this field is missing from the service config, default system parameters will be used. Default system parameters and names is implementation-dependent.

Example: define api key for all methods

systemParameters
  rules:
    - selector: "*"
      parameters:
        - name: api_key
