Common response parameters

API responses use the HTTP response format where a status code of 2XX indicates a successful call and a status code of 4XX or 5XX indicates a failed call. Response data can be returned in either the JSON or XML format. You can specify the response format when you are making the request. The default response format is XML.

Every response has a unique RequestId regardless of whether the call was successful or not.
