Common response parameters

API responses use the HTTP response format. Responses can be returned in either the JSON or XML format. You can specify the response format in the request. The default response format is XML. Every response returns a unique request ID that is indicated by the RequestId parameter regardless of whether the call is successful.
  • A 2xx HTTP status code indicates a successful call.
  • A 4xx or 5xx HTTP status code indicates a failed call.
Sample responses
