After the operation is called, data is returned in a unified format. A returned HTTP status code of 2xx indicates that the call was successful. A returned HTTP status code of 4xx or 5xx indicates that the call failed. If the call succeeds, data can be returned in either XML or JSON format. When sending a request from an external system, you can enter a parameter that specifies the returned data format. The default format is XML.

Note Sample responses in our API documents are formatted in a way that is easier for you to read. The actual responses are not formatted with line breaks or indentation.
