In response to an HTTP request, Amazon MWS returns an XML file that contains the results of the request. If a request is successful, the response is returned with the data requested. The following example shows a successful response.
<?xml version="1.0"?> <RequestReportResponse xmlns="http://mws.amazonservices.com/doc/2009-01-01/"> <RequestReportResult> <ReportRequestInfo> <ReportRequestId>2291326454</ReportRequestId> <ReportType>_GET_MERCHANT_LISTINGS_DATA_</ReportType> <StartDate>2009-01-21T02:10:39+00:00</StartDate> <EndDate>2009-02-13T02:10:39+00:00</EndDate> <Scheduled>false</Scheduled> <SubmittedDate>2009-02-20T02:10:39+00:00</SubmittedDate> <ReportProcessingStatus>_SUBMITTED_</ReportProcessingStatus> </ReportRequestInfo> </RequestReportResult> <ResponseMetadata> <RequestId>88faca76-b600-46d2-b53c-0c8c4533e43a</RequestId> </ResponseMetadata> </RequestReportResponse>
For more information about errors and error handling, see Error Messages.
The following example shows an error response:
<ErrorResponse xmlns="http://mws.amazonservices.com/doc/2009-01-01/"> <Error> <Type>Sender</Type> <Code>InvalidClientTokenId</Code> <Message> The AWS Access Key Id you provided does not exist in our records. </Message> <Detail>com.amazonservices.mws.model.Error$Detail@17b6643</Detail> </Error> <RequestID>b7afc6c3-6f75-4707-bcf4-0475ad23162c</RequestID> </ErrorResponse>
XML responses are limited to the Unicode characters compatible with the Extensible Markup Language (XML) 1.0:
Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
If a response includes a character outside of that range, Amazon MWS returns Unicode #xFFFD (�) in place of that character.
