Set Object Storage Class

To change an object's storage class with the XML API, you must overwrite the existing object (creating a new object version). Make a PUT request that is scoped to the object. The request should contain the x-goog-storage-class reference header, as well as the object in the request body. Note that based on the location of the bucket in which the object resides, there are restrictions on the storage class you can set for the object.

To learn more about per-object storage classes in general, see the associated concept page.
