Types overview

AppEngineHttpRequest

App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. Using AppEngineHttpRequest requires appengine.applications.get Google IAM permission for the project and the following scope: https://www.googleapis.com/auth/cloud-platform The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see How Requests are Routed and how routing is affected by dispatch files. Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If app_engine_routing_override is set on the queue, this value is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The url that the task will be sent to is: * url = host + relative_uri Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with login: admin. Because tasks are not run as any user, they cannot be dispatched to URIs restricted with login: required Task dispatches also do not follow redirects. The task attempt has succeeded if the app's request handler returns an HTTP response code in the range [200 - 299]. The task attempt has failed if the app's handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. 503 (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks' traffic congestion control to temporarily throttle the queue's dispatches. Unlike other types of task targets, a 429 (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue.

Fields
appEngineRouting	object (AppEngineRouting) Task-level setting for App Engine routing. * If app_engine_routing_override is set on the queue, this value is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing.
body	string (bytes format) HTTP request body. A request body is allowed only if the HTTP method is POST or PUT. It is an error to set a body on a task with an incompatible HttpMethod.
headers	map (key: string, value: string) HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * User-Agent: By default, this header is "AppEngine-Google; (+http://code.google.com/appengine)". This header can be modified, but Cloud Tasks will append "AppEngine-Google; (+http://code.google.com/appengine)" to the modified User-Agent. If the task has a body, Cloud Tasks sets the following headers: * Content-Type: By default, the Content-Type header is set to "application/octet-stream". The default can be overridden by explicitly setting Content-Type to a particular media type when the task is created. For example, Content-Type can be set to "application/json". * Content-Length: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * Host * X-Google-* * X-AppEngine-* In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see request headers. These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.
httpMethod	enum The HTTP method to use for the request. The default is POST. The app's request handler for the task's target URL must be able to handle HTTP requests with this http_method, otherwise the task attempt fails with error code 405 (Method Not Allowed). See Writing a push task request handler and the App Engine documentation for your runtime on How Requests are Handled.
Enum type. Can be one of the following:
HTTP_METHOD_UNSPECIFIED	HTTP method unspecified
POST	HTTP POST
GET	HTTP GET
HEAD	HTTP HEAD
PUT	HTTP PUT
DELETE	HTTP DELETE
PATCH	HTTP PATCH
OPTIONS	HTTP OPTIONS
relativeUri	string The relative URI. The relative URI must begin with "/" and must be a valid HTTP relative URI. It can contain a path and query string arguments. If the relative URI is empty, then the root path "/" will be used. No spaces are allowed, and the maximum length allowed is 2083 characters.

AppEngineRouting

App Engine Routing. Defines routing characteristics specific to App Engine - service, version, and instance. For more information about services, versions, and instances see An Overview of App Engine, Microservices Architecture on Google App Engine, App Engine Standard request routing, and App Engine Flex request routing. Using AppEngineRouting requires appengine.applications.get Google IAM permission for the project and the following scope: https://www.googleapis.com/auth/cloud-platform

Fields
host	string Output only. The host that the task is sent to. The host is constructed from the domain name of the app associated with the queue's project ID (for example .appspot.com), and the service, version, and instance. Tasks which were created using the App Engine SDK might have a custom domain name. For more information, see How Requests are Routed.
instance	string App instance. By default, the task is sent to an instance which is available when the task is attempted. Requests can only be sent to a specific instance if manual scaling is used in App Engine Standard. App Engine Flex does not support instances. For more information, see App Engine Standard request routing and App Engine Flex request routing.
service	string App service. By default, the task is sent to the service which is the default service when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
version	string App version. By default, the task is sent to the version which is the default version when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.

Attempt

The status of a task attempt.

Fields
dispatchTime	string (Timestamp format) Output only. The time that this attempt was dispatched. dispatch_time will be truncated to the nearest microsecond.
responseStatus	object (Status) Output only. The response from the worker for this attempt. If response_time is unset, then the task has not been attempted or is currently running and the response_status field is meaningless.
responseTime	string (Timestamp format) Output only. The time that this attempt response was received. response_time will be truncated to the nearest microsecond.
scheduleTime	string (Timestamp format) Output only. The time that this attempt was scheduled. schedule_time will be truncated to the nearest microsecond.

Binding

Associates members with a role.

Fields
condition	object (Expr) The condition that is associated with this binding. If the condition evaluates to true, then this binding applies to the current request. If the condition evaluates to false, then this binding does not apply to the current request. However, a different role binding might grant the same role to one or more of the members in this binding. To learn which resources support conditions in their IAM policies, see the IAM documentation.
members[]	string Specifies the identities requesting access for a Cloud Platform resource. members can have the following values: * allUsers: A special identifier that represents anyone who is on the internet; with or without a Google account. * allAuthenticatedUsers: A special identifier that represents anyone who is authenticated with a Google account or a service account. * user:{emailid}: An email address that represents a specific Google account. For example, [e-mail] . * serviceAccount:{emailid}: An email address that represents a service account. For example, [e-mail]. * group:{emailid}: An email address that represents a Google group. For example, [e-mail]. * deleted:user:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a user that has been recently deleted. For example, [e-mail]?uid=123456789012345678901. If the user is recovered, this value reverts to user:{emailid} and the recovered user retains the role in the binding. * deleted:serviceAccount:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a service account that has been recently deleted. For example, [e-mail]?uid=123456789012345678901. If the service account is undeleted, this value reverts to serviceAccount:{emailid} and the undeleted service account retains the role in the binding. * deleted:group:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a Google group that has been recently deleted. For example, [e-mail]?uid=123456789012345678901. If the group is recovered, this value reverts to group:{emailid} and the recovered group retains the role in the binding. * domain:{domain}: The G Suite domain (primary) that represents all the users of that domain. For example, google.com or example.com.
role	string Role that is assigned to members. For example, roles/viewer, roles/editor, or roles/owner.

CreateTaskRequest

Request message for CreateTask.

Fields
responseView	enum The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires cloudtasks.tasks.fullView Google IAM permission on the Task resource.
Enum type. Can be one of the following:
VIEW_UNSPECIFIED	Unspecified. Defaults to BASIC.
BASIC	The basic view omits fields which can be large or can contain sensitive data. This view does not include the body in AppEngineHttpRequest. Bodies are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.
FULL	All information is returned. Authorization for FULL requires cloudtasks.tasks.fullView Google IAM permission on the Queue resource.
task	object (Task) Required. The task to add. Task names have the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID. The user can optionally specify a task name. If a name is not specified then the system will generate a random unique task id, which will be set in the task returned in the response. If schedule_time is not set or is in the past then Cloud Tasks will set it to the current time. Task De-duplication: Explicitly specifying a task ID enables task de-duplication. If a task's ID is identical to that of an existing task or a task that was deleted or executed recently then the call will fail with ALREADY_EXISTS. If the task's queue was created using Cloud Tasks, then another task with the same name can't be created for ~1hour after the original task was deleted or executed. If the task's queue was created using queue.yaml or queue.xml, then another task with the same name can't be created for ~9days after the original task was deleted or executed. Because there is an extra lookup cost to identify duplicate task names, these CreateTask calls have significantly increased latency. Using hashed strings for the task id or for the prefix of the task id is recommended. Choosing task ids that are sequential or have sequential prefixes, for example using a timestamp, causes an increase in latency and error rates in all task commands. The infrastructure relies on an approximately uniform distribution of task ids to store and serve tasks efficiently.

Expr

Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language. The syntax and semantics of CEL are documented at https://github.com/google/cel-spec. Example (Comparison): title: "Summary size limit" description: "Determines if a summary is less than 100 chars" expression: "document.summary.size() < 100" Example (Equality): title: "Requestor is owner" description: "Determines if requestor is the document owner" expression: "document.owner == request.auth.claims.email" Example (Logic): title: "Public documents" description: "Determine whether the document should be publicly visible" expression: "document.type != 'private' && document.type != 'internal'" Example (Data Manipulation): title: "Notification string" description: "Create a notification string with a timestamp." expression: "'New message received at ' + string(document.create_time)" The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information.

Fields
description	string Optional. Description of the expression. This is a longer text which describes the expression, e.g. when hovered over it in a UI.
expression	string Textual representation of an expression in Common Expression Language syntax.
location	string Optional. String indicating the location of the expression for error reporting, e.g. a file name and a position in the file.
title	string Optional. Title for the expression, i.e. a short string describing its purpose. This can be used e.g. in UIs which allow to enter the expression.

GetIamPolicyRequest

Request message for GetIamPolicy method.

Fields
options	object (GetPolicyOptions) OPTIONAL: A GetPolicyOptions object for specifying options to GetIamPolicy.

GetPolicyOptions

Encapsulates settings provided to GetIamPolicy.

Fields

requestedPolicyVersion

integer (int32 format) Optional. The policy format version to be returned. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional bindings must specify version 3. Policies without any conditional bindings may specify any valid value or leave the field unset. To learn which resources support conditions in their IAM policies, see the IAM documentation.

HttpRequest

HTTP request. The task will be pushed to the worker as an HTTP request. If the worker or the redirected worker acknowledges the task by returning a successful HTTP response code ([200 - 299]), the task will be removed from the queue. If any other HTTP response code is returned or no response is received, the task will be retried according to the following: * User-specified throttling: retry configuration, rate limits, and the queue's state. * System throttling: To prevent the worker from overloading, Cloud Tasks may temporarily reduce the queue's effective rate. User-specified settings will not be changed. System throttling happens because: * Cloud Tasks backs off on all errors. Normally the backoff specified in rate limits will be used. But if the worker returns 429 (Too Many Requests), 503 (Service Unavailable), or the rate of errors is high, Cloud Tasks will use a higher backoff rate. The retry specified in the Retry-After HTTP response header is considered. * To prevent traffic spikes and to smooth sudden increases in traffic, dispatches ramp up slowly when the queue is newly created or idle and if large numbers of tasks suddenly become available to dispatch (due to spikes in create task rates, the queue being unpaused, or many tasks that are scheduled at the same time).

Fields
body	string (bytes format) HTTP request body. A request body is allowed only if the HTTP method is POST, PUT, or PATCH. It is an error to set body on a task with an incompatible HttpMethod.
headers	map (key: string, value: string) HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. These headers represent a subset of the headers that will accompany the task's HTTP request. Some HTTP request headers will be ignored or replaced. A partial list of headers that will be ignored or replaced is: * Host: This will be computed by Cloud Tasks and derived from HttpRequest.url. * Content-Length: This will be computed by Cloud Tasks. * User-Agent: This will be set to "Google-Cloud-Tasks". * X-Google-: Google use only. * X-AppEngine-: Google use only. Content-Type won't be set by Cloud Tasks. You can explicitly set Content-Type to a media type when the task is created. For example, Content-Type can be set to "application/octet-stream" or "application/json". Headers which can have multiple values (according to RFC2616) can be specified using comma-separated values. The size of the headers must be less than 80KB.
httpMethod	enum The HTTP method to use for the request. The default is POST.
Enum type. Can be one of the following:
HTTP_METHOD_UNSPECIFIED	HTTP method unspecified
POST	HTTP POST
GET	HTTP GET
HEAD	HTTP HEAD
PUT	HTTP PUT
DELETE	HTTP DELETE
PATCH	HTTP PATCH
OPTIONS	HTTP OPTIONS
oauthToken	object (OAuthToken) If specified, an OAuth token will be generated and attached as an Authorization header in the HTTP request. This type of authorization should generally only be used when calling Google APIs hosted on *.googleapis.com.
oidcToken	object (OidcToken) If specified, an OIDC token will be generated and attached as an Authorization header in the HTTP request. This type of authorization can be used for many scenarios, including calling Cloud Run, or endpoints where you intend to validate the token yourself.
url	string Required. The full url path that the request will be sent to. This string must begin with either "http://" or "https://". Some examples are: http://acme.com and https://acme.com/sales:8080. Cloud Tasks will encode some characters for safety and compatibility. The maximum allowed URL length is 2083 characters after encoding. The Location header response from a redirect response [300 - 399] may be followed. The redirect is not counted as a separate attempt.

ListLocationsResponse

The response message for Locations.ListLocations.

Fields
locations[]	object (Location) A list of locations that matches the specified filter in the request.
nextPageToken	string The standard List next-page token.

ListQueuesResponse

Response message for ListQueues.

Fields
nextPageToken	string A token to retrieve next page of results. To return the next page of results, call ListQueues with this value as the page_token. If the next_page_token is empty, there are no more results. The page token is valid for only 2 hours.
queues[]	object (Queue) The list of queues.

ListTasksResponse

Response message for listing tasks using ListTasks.

Fields
nextPageToken	string A token to retrieve next page of results. To return the next page of results, call ListTasks with this value as the page_token. If the next_page_token is empty, there are no more results.
tasks[]	object (Task) The list of tasks.

Location

A resource that represents Google Cloud Platform location.

Fields
displayName	string The friendly name for this location, typically a nearby city name. For example, "Tokyo".
labels	map (key: string, value: string) Cross-service attributes for the location. For example {"cloud.googleapis.com/region": "us-east1"}
locationId	string The canonical id for this location. For example: "us-east1".
metadata	map (key: string, value: any) Service-specific metadata. For example the available capacity at the given location.
name	string Resource name for the location, which may vary between implementations. For example: "projects/example-project/locations/us-east1"

OAuthToken

Contains information needed for generating an OAuth token. This type of authorization should generally only be used when calling Google APIs hosted on *.googleapis.com.

Fields
scope	string OAuth scope to be used for generating OAuth access token. If not specified, "https://www.googleapis.com/auth/cloud-platform" will be used.
serviceAccountEmail	string Service account email to be used for generating OAuth token. The service account must be within the same project as the queue. The caller must have iam.serviceAccounts.actAs permission for the service account.

OidcToken

Contains information needed for generating an OpenID Connect token. This type of authorization can be used for many scenarios, including calling Cloud Run, or endpoints where you intend to validate the token yourself.

Fields
audience	string Audience to be used when generating OIDC token. If not specified, the URI specified in target will be used.
serviceAccountEmail	string Service account email to be used for generating OIDC token. The service account must be within the same project as the queue. The caller must have iam.serviceAccounts.actAs permission for the service account.

Policy

An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions; each role can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a binding can also specify a condition, which is a logical expression that allows access to a resource only if the expression evaluates to true. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the IAM documentation. JSON example: { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:[e-mail]", "group:[e-mail]", "domain:google.com", "serviceAccount:[e-mail]" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:[e-mail]" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } YAML example: bindings: - members: - user:[e-mail] - group:[e-mail] - domain:google.com - serviceAccount:[e-mail] role: roles/resourcemanager.organizationAdmin - members: - user:[e-mail] role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') - etag: BwWWja0YfJA= - version: 3 For a description of IAM and its features, see the IAM documentation.

Fields
bindings[]	object (Binding) Associates a list of members to a role. Optionally, may specify a condition that determines how and when the bindings are applied. Each of the bindings must contain at least one member.
etag	string (bytes format) etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An etag is returned in the response to getIamPolicy, and systems are expected to put that etag in the request to setIamPolicy to ensure that their change will be applied to the same version of the policy. Important: If you use IAM Conditions, you must include the etag field whenever you call setIamPolicy. If you omit this field, then IAM allows you to overwrite a version 3 policy with a version 1 policy, and all of the conditions in the version 3 policy are lost.
version	integer (int32 format) Specifies the format of the policy. Valid values are 0, 1, and 3. Requests that specify an invalid value are rejected. Any operation that affects conditional role bindings must specify version 3. This requirement applies to the following operations: * Getting a policy that includes a conditional role binding * Adding a conditional role binding to a policy * Changing a conditional role binding in a policy * Removing any role binding, with or without a condition, from a policy that includes conditions Important: If you use IAM Conditions, you must include the etag field whenever you call setIamPolicy. If you omit this field, then IAM allows you to overwrite a version 3 policy with a version 1 policy, and all of the conditions in the version 3 policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the IAM documentation.

Queue

A queue is a container of related tasks. Queues are configured to manage how those tasks are dispatched. Configurable properties include rate limits, retry options, queue types, and others.

Fields
appEngineRoutingOverride	object (AppEngineRouting) Overrides for task-level app_engine_routing. These settings apply only to App Engine tasks in this queue. Http tasks are not affected. If set, app_engine_routing_override is used for all App Engine tasks in the queue, no matter what the setting is for the task-level app_engine_routing.
name	string Caller-specified and required in CreateQueue, after which it becomes output only. The queue name. The queue name must have the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID * PROJECT_ID can contain letters ([A-Za-z]), numbers ([0-9]), hyphens (-), colons (:), or periods (.). For more information, see Identifying projects * LOCATION_ID is the canonical ID for the queue's location. The list of available locations can be obtained by calling ListLocations. For more information, see https://cloud.google.com/about/locations/. * QUEUE_ID can contain letters ([A-Za-z]), numbers ([0-9]), or hyphens (-). The maximum length is 100 characters.
purgeTime	string (Timestamp format) Output only. The last time this queue was purged. All tasks that were created before this time were purged. A queue can be purged using PurgeQueue, the App Engine Task Queue SDK, or the Cloud Console. Purge time will be truncated to the nearest microsecond. Purge time will be unset if the queue has never been purged.
rateLimits	object (RateLimits) Rate limits for task dispatches. rate_limits and retry_config are related because they both control task attempts. However they control task attempts in different ways: * rate_limits controls the total rate of dispatches from a queue (i.e. all traffic dispatched from the queue, regardless of whether the dispatch is from a first attempt or a retry). * retry_config controls what happens to particular a task after its first attempt fails. That is, retry_config controls task retries (the second attempt, third attempt, etc). The queue's actual dispatch rate is the result of: * Number of tasks in the queue * User-specified throttling: rate_limits, retry_config, and the queue's state. * System throttling due to 429 (Too Many Requests) or 503 (Service Unavailable) responses from the worker, high error rates, or to smooth sudden large traffic spikes.
retryConfig	object (RetryConfig) Settings that determine the retry behavior. * For tasks created using Cloud Tasks: the queue-level retry settings apply to all tasks in the queue that were created using Cloud Tasks. Retry settings cannot be set on individual tasks. * For tasks created using the App Engine SDK: the queue-level retry settings apply to all tasks in the queue which do not have retry settings explicitly set on the task and were created by the App Engine SDK. See App Engine documentation.
stackdriverLoggingConfig	object (StackdriverLoggingConfig) Configuration options for writing logs to Stackdriver Logging. If this field is unset, then no logs are written.
state	enum Output only. The state of the queue. state can only be changed by calling PauseQueue, ResumeQueue, or uploading queue.yaml/xml. UpdateQueue cannot be used to change state.
Enum type. Can be one of the following:
STATE_UNSPECIFIED	Unspecified state.
RUNNING	The queue is running. Tasks can be dispatched. If the queue was created using Cloud Tasks and the queue has had no activity (method calls or task dispatches) for 30 days, the queue may take a few minutes to re-activate. Some method calls may return NOT_FOUND and tasks may not be dispatched for a few minutes until the queue has been re-activated.
PAUSED	Tasks are paused by the user. If the queue is paused then Cloud Tasks will stop delivering tasks from it, but more tasks can still be added to it by the user.
DISABLED	The queue is disabled. A queue becomes DISABLED when queue.yaml or queue.xml is uploaded which does not contain the queue. You cannot directly disable a queue. When a queue is disabled, tasks can still be added to a queue but the tasks are not dispatched. To permanently delete this queue and all of its tasks, call DeleteQueue.

RateLimits

Rate limits. This message determines the maximum rate that tasks can be dispatched by a queue, regardless of whether the dispatch is a first task attempt or a retry. Note: The debugging command, RunTask, will run a task even if the queue has reached its RateLimits.

Fields
maxBurstSize	integer (int32 format) Output only. The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The token bucket algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by max_burst_size. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. Cloud Tasks will pick the value of max_burst_size based on the value of max_dispatches_per_second. For queues that were created or updated using queue.yaml/xml, max_burst_size is equal to bucket_size. Since max_burst_size is output only, if UpdateQueue is called on a queue created by queue.yaml/xml, max_burst_size will be reset based on the value of max_dispatches_per_second, regardless of whether max_dispatches_per_second is updated.
maxConcurrentDispatches	integer (int32 format) The maximum number of concurrent tasks that Cloud Tasks allows to be dispatched for this queue. After this threshold has been reached, Cloud Tasks stops dispatching tasks until the number of concurrent requests decreases. If unspecified when the queue is created, Cloud Tasks will pick the default. The maximum allowed value is 5,000. This field has the same meaning as max_concurrent_requests in queue.yaml/xml.
maxDispatchesPerSecond	number (double format) The maximum rate at which tasks are dispatched from this queue. If unspecified when the queue is created, Cloud Tasks will pick the default. * The maximum allowed value is 500. This field has the same meaning as rate in queue.yaml/xml.

RetryConfig

Retry config. These settings determine when a failed task attempt is retried.

Fields
maxAttempts	integer (int32 format) Number of attempts per task. Cloud Tasks will attempt the task max_attempts times (that is, if the first attempt fails, then there will be max_attempts - 1 retries). Must be >= -1. If unspecified when the queue is created, Cloud Tasks will pick the default. -1 indicates unlimited attempts. This field has the same meaning as task_retry_limit in queue.yaml/xml.
maxBackoff	string (Duration format) A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried. If unspecified when the queue is created, Cloud Tasks will pick the default. max_backoff will be truncated to the nearest second. This field has the same meaning as max_backoff_seconds in queue.yaml/xml.
maxDoublings	integer (int32 format) The time between retries will double max_doublings times. A task's retry interval starts at min_backoff, then doubles max_doublings times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and max_doublings is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, .... If unspecified when the queue is created, Cloud Tasks will pick the default. This field has the same meaning as max_doublings in queue.yaml/xml.
maxRetryDuration	string (Duration format) If positive, max_retry_duration specifies the time limit for retrying a failed task, measured from when the task was first attempted. Once max_retry_duration time has passed and the task has been attempted max_attempts times, no further attempts will be made and the task will be deleted. If zero, then the task age is unlimited. If unspecified when the queue is created, Cloud Tasks will pick the default. max_retry_duration will be truncated to the nearest second. This field has the same meaning as task_age_limit in queue.yaml/xml.
minBackoff	string (Duration format) A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried. If unspecified when the queue is created, Cloud Tasks will pick the default. min_backoff will be truncated to the nearest second. This field has the same meaning as min_backoff_seconds in queue.yaml/xml.

RunTaskRequest

Request message for forcing a task to run now using RunTask.

Fields
responseView	enum The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires cloudtasks.tasks.fullView Google IAM permission on the Task resource.
Enum type. Can be one of the following:
VIEW_UNSPECIFIED	Unspecified. Defaults to BASIC.
BASIC	The basic view omits fields which can be large or can contain sensitive data. This view does not include the body in AppEngineHttpRequest. Bodies are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.
FULL	All information is returned. Authorization for FULL requires cloudtasks.tasks.fullView Google IAM permission on the Queue resource.

SetIamPolicyRequest

Request message for SetIamPolicy method.

Fields
policy	object (Policy) REQUIRED: The complete policy to be applied to the resource. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Cloud Platform services (such as Projects) might reject them.

StackdriverLoggingConfig

Configuration options for writing logs to Stackdriver Logging.

Fields
samplingRatio	number (double format) Specifies the fraction of operations to write to Stackdriver Logging. This field may contain any value between 0.0 and 1.0, inclusive. 0.0 is the default and means that no operations are logged.

Status

The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC. Each Status message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the API Design Guide.

Fields
code	integer (int32 format) The status code, which should be an enum value of google.rpc.Code.
details[]	object A list of messages that carry the error details. There is a common set of message types for APIs to use.
message	string A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.

Task

A unit of scheduled work.

Fields
appEngineHttpRequest	object (AppEngineHttpRequest) HTTP request that is sent to the App Engine app handler. An App Engine task is a task that has AppEngineHttpRequest set.
createTime	string (Timestamp format) Output only. The time that the task was created. create_time will be truncated to the nearest second.
dispatchCount	integer (int32 format) Output only. The number of attempts dispatched. This count includes attempts which have been dispatched but haven't received a response.
dispatchDeadline	string (Duration format) The deadline for requests sent to the worker. If the worker does not respond by this deadline then the request is cancelled and the attempt is marked as a DEADLINE_EXCEEDED failure. Cloud Tasks will retry the task according to the RetryConfig. Note that when the request is cancelled, Cloud Tasks will stop listening for the response, but whether the worker stops processing depends on the worker. For example, if the worker is stuck, it may not react to cancelled requests. The default and maximum values depend on the type of request: * For HTTP tasks, the default is 10 minutes. The deadline must be in the interval [15 seconds, 30 minutes]. * For App Engine tasks, 0 indicates that the request has the default deadline. The default deadline depends on the scaling type of the service: 10 minutes for standard apps with automatic scaling, 24 hours for standard apps with manual and basic scaling, and 60 minutes for flex apps. If the request deadline is set, it must be in the interval [15 seconds, 24 hours 15 seconds]. Regardless of the task's dispatch_deadline, the app handler will not run for longer than than the service's timeout. We recommend setting the dispatch_deadline to at most a few seconds more than the app handler's timeout. For more information see Timeouts. dispatch_deadline will be truncated to the nearest millisecond. The deadline is an approximate deadline.
firstAttempt	object (Attempt) Output only. The status of the task's first attempt. Only dispatch_time will be set. The other Attempt information is not retained by Cloud Tasks.
httpRequest	object (HttpRequest) HTTP request that is sent to the worker. An HTTP task is a task that has HttpRequest set.
lastAttempt	object (Attempt) Output only. The status of the task's last attempt.
name	string Optionally caller-specified in CreateTask. The task name. The task name must have the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID * PROJECT_ID can contain letters ([A-Za-z]), numbers ([0-9]), hyphens (-), colons (:), or periods (.). For more information, see Identifying projects * LOCATION_ID is the canonical ID for the task's location. The list of available locations can be obtained by calling ListLocations. For more information, see https://cloud.google.com/about/locations/. * QUEUE_ID can contain letters ([A-Za-z]), numbers ([0-9]), or hyphens (-). The maximum length is 100 characters. * TASK_ID can contain only letters ([A-Za-z]), numbers ([0-9]), hyphens (-), or underscores (_). The maximum length is 500 characters.
responseCount	integer (int32 format) Output only. The number of attempts which have received a response.
scheduleTime	string (Timestamp format) The time when the task is scheduled to be attempted or retried. schedule_time will be truncated to the nearest microsecond.
view	enum Output only. The view specifies which subset of the Task has been returned.
Enum type. Can be one of the following:
VIEW_UNSPECIFIED	Unspecified. Defaults to BASIC.
BASIC	The basic view omits fields which can be large or can contain sensitive data. This view does not include the body in AppEngineHttpRequest. Bodies are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.
FULL	All information is returned. Authorization for FULL requires cloudtasks.tasks.fullView Google IAM permission on the Queue resource.
