  ],
  "etag": string
}
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
(deprecated)

number

Deprecated.

policy.bindings[]

object

Associates a list of members to a role. bindings with no members will result in an error.

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@gmail.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.

policy.bindings[].condition

object

Unimplemented. 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.

The application context of the containing message determines which well-known feature set of CEL is supported.

policy.bindings[].condition.title

string

An 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

An 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

An 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.

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

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@gmail.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.

bindings[].condition

object

Unimplemented. 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.

bindings[].condition.expression

string

Textual representation of an expression in Common Expression Language syntax.

The application context of the containing message determines which well-known feature set of CEL is supported.

bindings[].condition.title

string

An 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

An 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

An optional string indicating the location of the expression for error reporting, e.g. a file name and a position in the file.

etag

string (bytes format)

Flatten Policy to create a backward compatible wire-format. Deprecated. Use 'policy' to specify the etag.

A base64-encoded string.

Response body

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

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.

JSON 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"]
    }
  ]
}

YAML Example

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

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