Common response parameters

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 RequestID regardless of whether the call succeeds.
  • An HTTP status code of 2xx indicates that the call succeeds.
  • An HTTP status code of 4xx or 5xx indicates that the call failed.
The following are sample responses:
  • XML format
    <? xml version="1.0" encoding="utf-8"? > 
        <!--Result root node-->
        <API name+Response>
            <!--Returned request tag-->
            <!--Response result data-->
        </API name+Response>
  • JSON format
        /*Response result data*/
