Amazon Order API or Report API to get SKU number and total quantity sold?

问题

I want a list of all SKU for which there were any sales between the From Date and To Date with the quantity sold. I am all confused what to do - should I use Amazon MWS Order API for this or Report API for this? Does anyone have a c# code which shows how a report is requested and downloaded at my end for further processing i.e. saving the data in databases. Any help would be much appreciated.

p.s. I have a large volume of data

UPDATE: Meanwhile I have written this code to get the report type and save the data. Now the error is "Access to path denied"

private const string targetRptType = "_GET_CONVERGED_FLAT_FILE_ORDER_REPORT_DATA_";

try
{
    RequestReportRequest reportRequestRequest = new RequestReportRequest();
    reportRequestRequest.Merchant = merchantId;
    reportRequestRequest.ReportType = targetRptType;
    reportRequestRequest.StartDate = DateTime.Now.AddDays(-3);
    reportRequestRequest.EndDate = DateTime.Now;

    MarketplaceWebServiceConfig config = new MarketplaceWebServiceConfig();
    config.ServiceURL = "https://mws.amazonservices.com";

    MarketplaceWebService.MarketplaceWebService service = new MarketplaceWebServiceClient(accessKeyId, secretAccessKey, applicationName, applicationVersion, config);

    RequestReportResponse requestResponse = service.RequestReport(reportRequestRequest);
    Thread.Sleep(15000);
    Response.Write(requestResponse.RequestReportResult.ReportRequestInfo.ReportProcessingStatus);
    GetReportRequestListRequest reportRequestListRequest = new GetReportRequestListRequest();
    reportRequestListRequest.Merchant = merchantId;
    List<ReportRequestInfo> myListzz = new List<ReportRequestInfo>();

    GetReportRequestListResponse reportRequestListResponse = new GetReportRequestListResponse();
    reportRequestListResponse = service.GetReportRequestList(reportRequestListRequest);
    GetReportRequestListResult reportRequestListResult = new GetReportRequestListResult();
    reportRequestListResult = reportRequestListResponse.GetReportRequestListResult;
    myListzz = reportRequestListResult.ReportRequestInfo;
    while (myListzz[0].ReportProcessingStatus.ToString() != "_DONE_")
    {
        Thread.Sleep(20000);
        reportRequestListResponse = service.GetReportRequestList(reportRequestListRequest);
        reportRequestListResult = reportRequestListResponse.GetReportRequestListResult;
        myListzz = reportRequestListResult.ReportRequestInfo;
    }

    GetReportListRequest listRequest = new GetReportListRequest();
    listRequest.Merchant = merchantId;
    listRequest.ReportRequestIdList = new IdList();
    listRequest.ReportRequestIdList.Id.Add(requestResponse.RequestReportResult.ReportRequestInfo.ReportRequestId);

    GetReportListResponse listResponse = service.GetReportList(listRequest);


    //MessageBox.Show(listResponse.GetReportListResult.ReportInfo.ToString());
    GetReportListResult getReportListResult = listResponse.GetReportListResult;

    GetReportRequest reportRequest = new GetReportRequest();
    reportRequest.Merchant = merchantId;
    reportRequest.WithReportId(getReportListResult.ReportInfo[0].ReportId);

    GetReportResponse reportResponse = new GetReportResponse();
    try
    {
        reportRequest.Report = File.Open("C:\\AmazonReport.csv", FileMode.OpenOrCreate, FileAccess.ReadWrite);  // Getting error access to path denied
        reportResponse = service.GetReport(reportRequest);
    }
    catch (MarketplaceWebServiceException exe)
    {
        Response.Write(exe);
    }
    StreamReader sr = new StreamReader(reportRequest.Report);
    Response.Write(sr.ReadToEnd());
    sr.Close();

}
catch (MarketplaceWebServiceException ex)
{
    Response.Write(ex.Message);
}

Can anyone please check my code and suggest if this is the correct way to get data from a report? I am still not able to save the report.

UPDATE 2
I have changed the path and now the error is gone and the file is created but it is just a 1 kb file with 2 records.. looks like it is not fetching full data. Not sure if the code is correct or not. Checking this on scratchpad https://mws.amazonservices.com/scratchpad/index.html

回答1:

I would save the report in your current working directory. Access to C:\ is usually locked down unless you are running as an admin. Use the following if you want to be explicit (if you provide just a file name and not a fully justified path, it will also save in your current working directory)

reportRequest.Report = File.Open(Path.Combine(Directory.GetCurrentDirectory(), "AmazonReport.csv"), FileMode.OpenOrCreate, FileAccess.ReadWrite);

The Orders API would make this much easier in my opinion. You can request Orders using a Date range and get everything you need.
