Fields
policy

object

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 in general a valid policy but certain services (like Projects) might reject them.
policy.version

integer

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.
policy.bindings[]

object

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.
policy.bindings[].role

string

Role that is assigned to members. For example, roles/viewer, roles/editor, or roles/owner.
policy.bindings[].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.
policy.bindings[].condition

object

The condition that is associated with this binding. NOTE: An unsatisfied condition will not allow user access via current binding. Different bindings, including their conditions, are examined independently.
policy.bindings[].condition.expression

string

Textual representation of an expression in Common Expression Language syntax.
policy.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.
policy.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.
policy.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.
policy.auditConfigs[]

object

Specifies cloud audit logging configuration for this policy.
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.
policy.auditConfigs[].auditLogConfigs[]

object

The configuration for logging of each type of permission.
policy.auditConfigs[].auditLogConfigs[].logType

enum

The log type that this config enables.
policy.auditConfigs[].auditLogConfigs[].exemptedMembers[]

string

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

A base64-encoded string.
bindings[]

object

Flatten Policy to create a backwacd compatible wire-format. Deprecated. Use 'policy' to specify bindings.
bindings[].role

string

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

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.

Response body

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

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

integer

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.
