ObjectAccessControls

The ObjectAccessControls resources represent the Access Control Lists (ACLs) for objects within Cloud Storage. ACLs let you specify who has access to your data and to what extent.

Important: The methods for this resource fail with a 400 Bad Request response for buckets with uniform bucket-level access enabled. Use storage.buckets.getIamPolicy and storage.buckets.setIamPolicy to control access instead.

There are two roles that can be assigned to an entity:

READERs can get an object, though the acl property will not be revealed.
OWNERs are READERs, and they can get the acl property, update an object, and call all objectAccessControls methods on the object. The owner of an object is always an OWNER.

For more information, see Access Control, with the caveat that this API uses READER and OWNER instead of READ and FULL_CONTROL.

To try out the methods for this resource, see Methods.
