This is achieved via a `GET` request to a specific URL using gRPC Transcoding, with the operation's name as a path parameter. The request body must be empty. Successful calls will receive a response body containing an `Operation` instance. Authorization requires the `https://www.googleapis.com/auth/display-video` OAuth scope, and users are advised to poll this method every 30 seconds.\n"]]
