This guide contains technical reference information for the Cloud Storage JSON API. Like the XML API, it is RESTful, but it has slightly different URI endpoints and request syntax, and is specifically intended to be used with the Google Cloud Client Libraries.
This API reference is organized by resource type. Each resource type has one or more data representations and one or more methods.
URIs are relative to https://storage.googleapis.com/storage/v1, unless otherwise noted.
