Otherwise, on error, the API will:
- Return an HTTP response code of 400, if the request was invalid;
- Return an HTTP response code of 401, if the request was not authorized; or
- Return an HTTP response code of 500, if something else went wrong.
Both HTTP 400 and 500 responses will contain a REST Integration Standard Response Object with appropriate values for the Code and/or Message fields, describing the error, in the response body.
