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 Scopes

Requires the following OAuth scope:

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

For more information, see the Authentication Overview.

SetIamPolicy

rpc SetIamPolicy(SetIamPolicyRequest) returns (Policy)

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

Can return Public Errors: NOT_FOUND, INVALID_ARGUMENT and PERMISSION_DENIED

Authorization Scopes

Requires the following OAuth scope:

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

For more information, see the Authentication Overview.

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.

Binding

Associates members with a role.

Fields
role

string

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

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@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.

  • deleted:user:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a user that has been recently deleted. For example, alice@example.com?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, my-other-app@appspot.gserviceaccount.com?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, admins@example.com?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.

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.

options

GetPolicyOptions

OPTIONAL: A GetPolicyOptions object for specifying options to GetIamPolicy. This field is only used by Cloud IAM.

GetPolicyOptions

Encapsulates settings provided to GetIamPolicy.

Fields
requested_policy_version

int32

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.

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.

Optionally, a binding can 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.

JSON example:

{
  "bindings": [
    {
      "role": "roles/resourcemanager.organizationAdmin",
      "members": [
        "user:mike@example.com",
        "group:admins@example.com",
        "domain:google.com",
        "serviceAccount:my-project-id@appspot.gserviceaccount.com"
      ]
    },
    {
      "role": "roles/resourcemanager.organizationViewer",
      "members": ["user:eve@example.com"],
      "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:mike@example.com
  - group:admins@example.com
  - domain:google.com
  - serviceAccount:my-project-id@appspot.gserviceaccount.com
  role: roles/resourcemanager.organizationAdmin
- members:
  - user:eve@example.com
  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
version

int32

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.

bindings[]

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

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.

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.

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.
