AmazonConnection amazonConnection = new AmazonConnection(new AmazonCredential()
{
     AccessKey = "AKIAXXXXXXXXXXXXXXX",
     SecretKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     RoleArn = "arn:aws:iam::XXXXXXXXXXXXX:role/XXXXXXXXXXXX",
     ClientId = "amzn1.application-XXX-client.XXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     ClientSecret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     RefreshToken= "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     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 };

var orders = amazonConnection.Orders.GetOrders(serachOrderList);

Order List data from Sandbox

AmazonConnection amazonConnection = new AmazonConnection(new AmazonCredential()
{
     AccessKey = "AKIAXXXXXXXXXXXXXXX",
     SecretKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     RoleArn = "arn:aws:iam::XXXXXXXXXXXXX:role/XXXXXXXXXXXX",
     ClientId = "amzn1.application-XXX-client.XXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     ClientSecret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     RefreshToken= "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
     Environment=Environments.Sandbox
});

var orders = amazonConnection.Orders.GetOrders
        (
         new FikaAmazonAPI.Parameter.Order.ParameterOrderList()
             {
              TestCase = Constants.TestCase200
             }
        );

Report List, For more report sample please check Here.

var parameters = new ParameterReportList();
parameters.pageSize = 100;
parameters.reportTypes = new List<ReportTypes>();
parameters.reportTypes.Add(ReportTypes.GET_AFN_INVENTORY_DATA);
parameters.marketplaceIds = new List<string>();
parameters.marketplaceIds.Add(MarketPlace.UnitedArabEmirates.ID);
var reports=amazonConnection.Reports.GetReports(parameters);

Custom Report

var parameters = new ParameterCreateReportSpecification();
parameters.reportType = ReportTypes.GET_FLAT_FILE_ALL_ORDERS_DATA_BY_LAST_UPDATE_GENERAL;
parameters.dataStartTime = DateTime.UtcNow.AddDays(-30);
parameters.dataEndTime = DateTime.UtcNow.AddDays(-10);
parameters.marketplaceIds = new MarketplaceIds();
parameters.marketplaceIds.Add(MarketPlace.UnitedArabEmirates.ID);
parameters.reportOptions = new AmazonSpApiSDK.Models.Reports.ReportOptions();

var report= amazonConnection.Reports.CreateReport(parameters);

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(

Notifications read messages

var SQS_URL = "https://sqs.us-east-2.amazonaws.com/9999999999999/IUSER_SQS";
ParameterMessageReceiver param = new ParameterMessageReceiver(
                    Environment.GetEnvironmentVariable("AccessKey"), 
                    Environment.GetEnvironmentVariable("SecretKey"), 
                    SQS_URL, Amazon.RegionEndpoint.USEast2);

CustomMessageReceiver messageReceiver = new CustomMessageReceiver();


amazonConnection.Notification.StartReceivingNotificationMessages(param, messageReceiver);
public class CustomMessageReceiver : IMessageReceiver
{
     public void ErrorCatch(Exception ex)
     {
         //Your code here
     }

     public void NewMessageRevicedTriger(NotificationMessageResponce message)
     {
         //Your Code here
     }
}

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.

ConstructFeedService createDocument = new ConstructFeedService("A3J37AJU4O9RHK", "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;

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
});
