IAMPolicy

API Overview

Manages Identity and Access Management (IAM) policies.

Any implementation of an API that offers access control features implements the google.iam.v1.IAMPolicy interface.

Data model

Access control is applied when a principal (user or service account), takes some action on a resource exposed by a service. Resources, identified by URI-like names, are the unit of access control specification. Service implementations can choose the granularity of access control and the supported permissions for their resources. For example one database service may allow access control to be specified only at the Table level, whereas another might allow access control to also be specified at the Column level.

Policy Structure

See google.iam.v1.Policy

This is intentionally not a CRUD style API because access control policies are created and deleted implicitly with the resources to which they are attached.

GetIamPolicy

rpc GetIamPolicy(GetIamPolicyRequest) returns (Policy)

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Authorization

Requires one of the following OAuth scopes:

  • https://www.googleapis.com/auth/pubsub
  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Auth Guide.

SetIamPolicy

rpc SetIamPolicy(SetIamPolicyRequest) returns (Policy)

Sets the access control policy on the specified resource. Replaces any existing policy.

Authorization

Requires one of the following OAuth scopes:

  • https://www.googleapis.com/auth/pubsub
  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Auth Guide.

TestIamPermissions

rpc TestIamPermissions(TestIamPermissionsRequest) returns (TestIamPermissionsResponse)

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Authorization

Requires one of the following OAuth scopes:

  • https://www.googleapis.com/auth/pubsub
  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Auth Guide.

Binding

Associates members with a role.

Fields
role

string

Role that is assigned to members. For example, roles/viewer, roles/editor, or roles/owner. Required

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, alice@gmail.com or joe@example.com.

  • serviceAccount:{emailid}: An email address that represents a service account. For example, my-other-app@appspot.gserviceaccount.com.

  • group:{emailid}: An email address that represents a Google group. For example, admins@example.com.

  • domain:{domain}: A Google Apps domain name that represents all the users of that domain. For example, google.com or example.com.

GetIamPolicyRequest

Request message for GetIamPolicy method.

Fields
resource

string

REQUIRED: The resource for which the policy is being requested. See the operation documentation for the appropriate value for this field.

Policy

Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources.

A Policy consists of a list of bindings. A Binding binds a list of members to a role, where the members can be user accounts, Google groups, Google domains, and service accounts. A role is a named list of permissions defined by IAM.

Example

{
  "bindings": [
    {
      "role": "roles/owner",
      "members": [
        "user:mike@example.com",
        "group:admins@example.com",
        "domain:google.com",
        "serviceAccount:my-other-app@appspot.gserviceaccount.com",
      ]
    },
    {
      "role": "roles/viewer",
      "members": ["user:sean@example.com"]
    }
  ]
}

For a description of IAM and its features, see the IAM developer's guide.

Fields
version

int32

Version of the Policy. The default version is 0.

bindings[]

Binding

Associates a list of members to a role. Multiple bindings must not be specified for the same role. bindings with no members will result in an error.

etag

bytes

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.

If no etag is provided in the call to setIamPolicy, then the existing policy is overwritten blindly.

SetIamPolicyRequest

Request message for SetIamPolicy method.

Fields
resource

string

REQUIRED: The resource for which the policy is being specified. See the operation documentation for the appropriate value for this field.

policy

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.

TestIamPermissionsRequest

Request message for TestIamPermissions method.

Fields
resource

string

REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.

permissions[]

string

The set of permissions to check for the resource. Permissions with wildcards (such as '*' or 'storage.*') are not allowed. For more information see IAM Overview.

TestIamPermissionsResponse

Response message for TestIamPermissions method.

Fields
permissions[]

string

A subset of TestPermissionsRequest.permissions that the caller is allowed.
