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 Google Cloud services (such as Projects) might reject them.
OPTIONAL: A FieldMask specifying which fields of the policy to modify. Only the fields in the mask will be modified. If no mask is provided, the following default mask is used:
paths: "bindings, etag"
This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo".
Response body
If successful, the response body contains an instance of Policy.
