Response body

An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources.

APolicy is a collection ofbindings. Abinding binds one or moremembers, or principals, to a singlerole. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). Arole is a named list of permissions; eachrole can be an IAM predefined role or a user-created custom role.

For some types of Google Cloud resources, abinding can also specify acondition, which is a logical expression that allows access to a resource only if the expression evaluates totrue. 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 theIAM documentation.

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 theIAM documentation.

If successful, the response body contains data with the following structure:

JSON representation
{"version":integer,"bindings":[{"role":string,"members":[string],"condition":{"expression":string,"title":string,"description":string,"location":string}}],"auditConfigs":[{"service":string,"auditLogConfigs":[{"logType":enum,"exemptedMembers":[string]}]}],"etag":string}
Fields
version

integer

Specifies the format of the policy.

Valid values are0,1, and3. Requests that specify an invalid value are rejected.

Any operation that affects conditional role bindings must specify version3. 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 theetag field whenever you callsetIamPolicy. If you omit this field, then IAM allows you to overwrite a version3 policy with a version1 policy, and all of the conditions in the version3 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 theIAM documentation.

bindings[]

object

Associates a list ofmembers, or principals, with arole. Optionally, may specify acondition that determines how and when thebindings are applied. Each of thebindings must contain at least one principal.

Thebindings in aPolicy can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if thebindings grant 50 different roles touser:alice@example.com, and not to any other principal, then you can add another 1,450 principals to thebindings in thePolicy.

bindings[].role

string

Role that is assigned to the list ofmembers, or principals. For example,roles/viewer,roles/editor, orroles/owner.

For an overview of the IAM roles and permissions, see theIAM documentation. For a list of the available pre-defined roles, seehere.

bindings[].members[]

string

Specifies the principals requesting access for a Google Cloud 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. Does not include identities that come from external identity providers (IdPs) through identity federation.

  • user:{emailid}: An email address that represents a specific Google account. For example,alice@example.com .

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

  • serviceAccount:{projectid}.svc.id.goog[{namespace}/{kubernetes-sa}]: An identifier for aKubernetes service account. For example,my-project.svc.id.goog[my-namespace/my-kubernetes-sa].

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

  • domain:{domain}: The G Suite domain (primary) that represents all the users of that domain. For example,google.com orexample.com.

  • principal://iam.googleapis.com/locations/global/workforcePools/{pool_id}/subject/{subject_attribute_value}: A single identity in a workforce identity pool.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/group/{groupId}: All workforce identities in a group.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/attribute.{attribute_name}/{attribute_value}: All workforce identities with a specific attribute value.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/*: All identities in a workforce identity pool.

  • principal://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/subject/{subject_attribute_value}: A single identity in a workload identity pool.

  • principalSet://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/group/{groupId}: A workload identity pool group.

  • principalSet://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/attribute.{attribute_name}/{attribute_value}: All identities in a workload identity pool with a certain attribute.

  • principalSet://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/*: All identities in a workload identity pool.

  • 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 touser:{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 toserviceAccount:{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 togroup:{emailid} and the recovered group retains the role in the binding.

  • deleted:principal://iam.googleapis.com/locations/global/workforcePools/{pool_id}/subject/{subject_attribute_value}: Deleted single identity in a workforce identity pool. For example,deleted:principal://iam.googleapis.com/locations/global/workforcePools/my-pool-id/subject/my-subject-attribute-value.

bindings[].condition

object

The condition that is associated with this binding.

If the condition evaluates totrue, then this binding applies to the current request.

If the condition evaluates tofalse, 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 principals in this binding.

To learn which resources support conditions in their IAM policies, see theIAM documentation.

bindings[].condition.expression

string

Textual representation of an expression in Common Expression Language syntax.

bindings[].condition.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.

bindings[].condition.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.

bindings[].condition.location

string

Optional. String indicating the location of the expression for error reporting, e.g. a file name and a position in the file.

auditConfigs[]

object

Specifies cloud audit logging configuration for this policy.

auditConfigs[].service

string

Specifies a service that will be enabled for audit logging. For example,storage.googleapis.com,cloudsql.googleapis.com.allServices is a special value that covers all services.

auditConfigs[].auditLogConfigs[]

object

The configuration for logging of each type of permission.

auditConfigs[].auditLogConfigs[].logType

enum

The log type that this config enables.

auditConfigs[].auditLogConfigs[].exemptedMembers[]

string

Specifies the identities that do not cause logging for this type of permission. Follows the same format ofBinding.members.

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 theetag in the read-modify-write cycle to perform policy updates in order to avoid race conditions: Anetag is returned in the response togetIamPolicy, and systems are expected to put that etag in the request tosetIamPolicy to ensure that their change will be applied to the same version of the policy.

Important: If you use IAM Conditions, you must include theetag field whenever you callsetIamPolicy. If you omit this field, then IAM allows you to overwrite a version3 policy with a version1 policy, and all of the conditions in the version3 policy are lost.

A base64-encoded string.
