Common request and response parameters

Common request headers

You must include common request parameters in every API call.

Example

Common response headers

The system returns a unique identifier, RequestId, for each API call, regardless of whether the call succeeds or fails. The data returned from an API call is in a unified format. An HTTP status code of 2xx indicates a successful call. An HTTP status code of 4xx or 5xx indicates a failed call.

XML example:

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

JSON example:

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