How to get the returns data like Returned Date,Merchant SKU,ASIN etc ., - mws

Question

I am newbie to MWS and working on returned items.
I have used Reports API .
$marketplaceIdArray = array("Id" => array('$MARKETPLACE_ID'));
$t1 = date("c", time()-437*24*60*60);
$t2 = date("c", time()-1*24*60*60);
// #TODO: set request. Action can be passed as
MarketplaceWebService_Model_ReportRequest
// object or array of parameters
$parameters = array (
'Merchant' => MERCHANT_ID,
'MarketplaceIdList' => $marketplaceIdArray,
'ReportType' => '_GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA_',
'ReportOptions' => 'ShowSalesChannel=true'
);
$request = new MarketplaceWebService_Model_RequestReportRequest($parameters);
$request = new MarketplaceWebService_Model_RequestReportRequest();
$request->setMarketplaceIdList($marketplaceIdArray);
$request->setStartDate($t1);
$request->setEndDate(t2);
$request->setMerchant(MERCHANT_ID);
$request->setReportType('_GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA_');
invokeRequestReport($service, $request);
the ouput was :
Service Response
RequestReportResponse
RequestReportResult
ReportRequestInfo
ReportRequestId
68409017536
ReportType
_GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA_

but how to fetch the fields like product name, quality, reson,SKU , etc ...,

Answer 1

You have requested the report.
Now you can use that request ID to check when the report has finished running. (You can test it all here before writing the php code: https://mws.amazonservices.com/scratchpad/index.html )
Go to Reports and choose GetReportRequestList and type in your requestID. This will then tell you if the ReportProcessingStatus is done or still processing. When it is done you can then get the GeneratedReportId and request the GetReport using that id. That will then give you a CSV result with your returns for the given time period from the initial report request.
If all of that looks good then you will need to add steps in your PHP code to do all of that.
Once you have requested the report you will need to save the request id and periodically (depending on your order volume, maybe check every few seconds or every minute to see if the request is done. Then you would have something like this:
$reportId = $this->invokeGetReportList($service, $request);
$reportRequest = new MarketplaceWebService_Model_GetReportRequest();
$reportRequest->setMerchant(MERCHANT_ID);
$reportRequest->setReport(#fopen('php://memory', 'rw+'));
$reportRequest->setReportId($reportId);
$resultArray = $this->invokeGetReportAllOrderData($service, $reportRequest);
