     MarketPlace = MarketPlace.UnitedArabEmirates, //MarketPlace.GetMarketPlaceByID("A2VIGQ35RCS4UG")
});

Order List, For more orders sample please check Here.

ParameterOrderList serachOrderList = new ParameterOrderList();
serachOrderList.CreatedAfter = DateTime.UtcNow.AddMinutes(-600000);
serachOrderList.OrderStatuses = new List<OrderStatuses>();
serachOrderList.OrderStatuses.Add(OrderStatuses.Canceled);
var orders = amazonConnection.Orders.GetOrders(serachOrderList);

Order List with parameter

ParameterOrderList serachOrderList = new ParameterOrderList();
serachOrderList.CreatedAfter = DateTime.UtcNow.AddHours(-24);
serachOrderList.OrderStatuses = new List<OrderStatuses>();
serachOrderList.OrderStatuses.Add(OrderStatuses.Unshipped);
serachOrderList.MarketplaceIds = new List<string> { MarketPlace.UnitedArabEmirates.ID };

             {
              TestCase = Constants.TestCase200
             }
        );

Report List, For more report sample please check Here.

Report Manager 🚀🧑‍🚀✨

Easy way to get the report you need and convert the file return from amazon to class or list, this feature only ready for some reports as its will take much times to finish for All report type ....

ReportManager reportManager = new ReportManager(amazonConnection);
var products = reportManager.GetProducts(); //GET_MERCHANT_LISTINGS_ALL_DATA
var inventoryAging = reportManager.GetInventoryAging(); //GET_FBA_INVENTORY_AGED_DATA
var ordersByDate = reportManager.GetOrdersByOrderDate(90); //GET_FLAT_FILE_ALL_ORDERS_DATA_BY_ORDER_DATE_GENERAL
var ordersByLastUpdate = reportManager.GetOrdersByLastUpdate(90); //GET_FLAT_FILE_ALL_ORDERS_DATA_BY_LAST_UPDATE_GENERAL
var settlementOrder = reportManager.GetSettlementOrder(90); //GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2
var returnMFNOrder = reportManager.GetReturnMFNOrder(90); //GET_FLAT_FILE_RETURNS_DATA_BY_RETURN_DATE
var returnFBAOrder = reportManager.GetReturnFBAOrder(90); //GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA
var reimbursementsOrder = reportManager.GetReimbursementsOrder(180); //GET_FBA_REIMBURSEMENTS_DATA
var feedbacks = reportManager.GetFeedbackFromDays(180); //GET_SELLER_FEEDBACK_DATA

Report GET_MERCHANT_LISTINGS_ALL_DATA sample

var parameters = new ParameterCreateReportSpecification();
parameters.reportType = ReportTypes.GET_MERCHANT_LISTINGS_ALL_DATA;

parameters.marketplaceIds = new MarketplaceIds();
parameters.marketplaceIds.Add(MarketPlace.UnitedArabEmirates.ID);

parameters.reportOptions = new FikaAmazonAPI.AmazonSpApiSDK.Models.Reports.ReportOptions();

var reportId = amazonConnection.Reports.CreateReport(parameters);
var filePath = string.Empty;
string ReportDocumentId = string.Empty;

while (string.IsNullOrEmpty(ReportDocumentId))
{
    Thread.Sleep(1000 * 60);
    var reportData = amazonConnection.Reports.GetReport(reportId);
    if (!string.IsNullOrEmpty(reportData.ReportDocumentId))
    {
        filePath = amazonConnection.Reports.GetReportFile(reportData.ReportDocumentId);
        break;
    }
}

//filePath for report

Product Pricing, For more Pricing sample please check Here.

var data = amazonConnection.ProductPricing.GetPricing(
    new Parameter.ProductPricing.ParameterGetPricing()
    {
        MarketplaceId = MarketPlace.UnitedArabEmirates.ID,
        Asins = new string[] { "B00CZC5F0G" }
    });

    new Parameter.ProductPricing.ParameterGetCompetitivePricing()
    {
        MarketplaceId = MarketPlace.UnitedArabEmirates.ID,
        Asins = new string[] { "B00CZC5F0G" },
    });

Notifications Create Destination, For more Notifications sample please check Here.

//EventBridge

        {
            EventBridge = new Notifications.EventBridgeResourceSpecification("us-east-2", "999999999")
        }
    });

Feed Submit

Here full sample for submit feed to change price and generate XML and get final report for result same as in doc. Notes: not all feed type finished as it's big work and effort but all classes are partial for easy change and you can generate XML outside and use our library to get data, now we support only submit existing product, change quantity and change price , I list most of XSD here Source\FikaAmazonAPI\ConstructFeed\xsd its will help you easy generate class and add it in your app to generate final feed xml.

Feed Submit for change price

ConstructFeedService createDocument = new ConstructFeedService("{SellerID}", "1.02");

var list = new List<PriceMessage>();
list.Add(new PriceMessage()
{
    SKU = "8201031206122...",
    StandardPrice = new StandardPrice()
    {
        currency = BaseCurrencyCode.AED.ToString(),
        Value = (201.0522M).ToString("0.00")
    }
});
createDocument.AddPriceMessage(list);

var xml = createDocument.GetXML();

var feedID = amazonConnection.Feed.SubmitFeed(xml, FeedType.POST_PRODUCT_PRICING_DATA);

Thread.Sleep(1000*30);

var feedOutput=amazonConnection.Feed.GetFeed(feedID);

var outPut=amazonConnection.Feed.GetFeedDocument(feedOutput.ResultFeedDocumentId);

var reportOutpit = outPut.Url;

var processingReport = amazonConnection.Feed.GetFeedDocumentProcessingReport(outPut.Url);

Feed Submit for change Quantity

ConstructFeedService createDocument = new ConstructFeedService("{SellerID}", "1.02");

var list = new List<InventoryMessage>();
list.Add(new InventoryMessage()
  {
    SKU = "82010312061.22...",
    Quantity = 2,
    FulfillmentLatency = "11",
 });

createDocument.AddInventoryMessage(list);

var xml = createDocument.GetXML();

var feedID = amazonConnection.Feed.SubmitFeed(xml, FeedType.POST_INVENTORY_AVAILABILITY_DATA);

Thread.Sleep(1000*30);

var feedOutput=amazonConnection.Feed.GetFeed(feedID);

var outPut=amazonConnection.Feed.GetFeedDocument(feedOutput.ResultFeedDocumentId);

var reportOutpit = outPut.Url;

var processingReport = amazonConnection.Feed.GetFeedDocumentProcessingReport(outPut.Url);

Usage Plans and Rate Limits in the Selling Partner API

Please read this doc to get all information about this limitation https://github.com/amzn/selling-partner-api-docs/blob/main/guides/en-US/usage-plans-rate-limits/Usage-Plans-and-Rate-Limits.md

we calc waiting time by read x-amzn-RateLimit-Limit header

int sleepTime = (int)((1 / header["x-amzn-RateLimit-Limit"] ) * 1000);

You can also disable libary from handelling limitaion by set IsActiveLimitRate=false in AmazonCredential

var amazonConnection = new AmazonConnection(new AmazonCredential()
{
      .
      .
      IsActiveLimitRate=false
});
