Common response parameters

API responses use a unified format. For successful calls, the response data is in XML or JSON format. You can specify the data format when you send a request. The default format is XML. A unique identifier, RequestId, is returned for every API call, 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.

The following examples show common responses:

XML format

<?xml version="1.0" encoding="utf-8"?> 
    <!--The root node of the result-->
    <APIName+Response>
        <!--The request ID tag-->
        <RequestId>4C467B38-3910-447D-87BC-AC049166F216</RequestId>
        <!--The response data-->
    </APIName+Response>

JSON format

{
    "RequestId":"4C467B38-3910-447D-87BC-AC049166F216",
    /*The response data*/
    }
