When the API service is called, the returned data adopts a uniform format. A returned HTTP status code of 2xx indicates that the call is successful. A returned HTTP status code of 4xx or 5xx indicates that the call has failed.
Two formats for the data returned after a successful call are XML and JSON. When sending a request, parameters specifying the format of returned data can be entered in the external system. XML is the default format.
In this document, examples of returned results are formatted for easy viewing. The actual results returned are not formatted with line breaks and indentation.
