code detail:

public String PostAmazonShipmentTracking(string mRefreshToken, string mSellerID, string mAmazonOrderID, string mCarrierName, string mShippingMethod, string mShipperTrackingNumber, string mCarrierCode, string mClientId, string mClientSecret)
{
//MarketPlace = MarketPlace.GetMarketPlaceByID("ATVPDKIKX0DER"),
AmazonConnection amazonConnection = new AmazonConnection(new AmazonCredential()
{
AccessKey = "XXX",
SecretKey = "XXX",
RoleArn = "XXX",
ClientId = mClientId,

            list.Add(new OrderFulfillmentMessage()
            {
                AmazonOrderID = mAmazonOrderID,
                //FulfillmentDate = DateTime.UtcNow.ToString(),
                FulfillmentDate = DateTime.Now.ToString("yyyy-MM-dd'T'HH:mm:ss.fffK"),
                FulfillmentData = new FulfillmentData()
                {
                    CarrierCode = mCarrierName,
                    CarrierName = mCarrierName,
                    ShippingMethod = mShippingMethod,
                    ShipperTrackingNumber = mShipperTrackingNumber
                }
            });
        
        createDocument.AddOrderFulfillmentMessage(list);

        var xml = createDocument.GetXML();

Hey, i think there is a problem with your credentials.

Try to remove the AccessKey, SecretKey and RoleArn from your AmazonCredential, with the refreshtoken you need this information anymore and check your ClientId ,ClientSecret and RefresToken again.

new AmazonCredential()
{
    ClientId = 'XXX',
    ClientSecret = 'XXX',
    RefreshToken = 'XXX',
    MarketPlace = MarketPlace.Germany
};

You can also try to remove CarrierName and ShippingMethod from FulfillmentData. I used it like this without any issues.

list.Add(new OrderFulfillmentMessage()
{
    AmazonOrderID = order.AmazonOrderId,
    FulfillmentDate = order.ShippingTime,
    FulfillmentData = new FulfillmentData()
    {
        CarrierCode = order.Carrier,
        ShipperTrackingNumber = order.Trackingnumber,
    }
});

Hi @abuzuhri

I have implemented the POST_ORDER_FULFILLMENT_DATA API posting through FIKA
First I send the tracking detail on amazon through FIKA using below method

createDocument.AddOrderFulfillmentMessage(list);
var xml = createDocument.GetXML();
string feedID = amazonConnection.Feed.SubmitFeed(xml, FeedType.POST_ORDER_FULFILLMENT_DATA);

which is running fine, but when I Post the tracking through SubmitFeed() method as mentioned above I get the FeedID
from amazon
then I make a new request to get the Status of that FeedID through the below method:

feedOutput=amazonConnection.Feed.GetFeed(mFeedID);
if(feedOutput.ResultFeedDocumentId is not null)
{
var outPut=amazonConnection.Feed.GetFeedDocument(feedOutput.ResultFeedDocumentId);
if (outPut is not null)
{
var processingReport = amazonConnection.Feed.GetFeedDocumentProcessingReport(outPut.Url);
resultCatalogFeed.FeedSubbmisionID = processingReport.DocumentTransactionID;
resultCatalogFeed.TotalProductSubmited =
Convert.ToInt32(processingReport.ProcessingSummary.MessagesProcessed);
resultCatalogFeed.SuccessCount =
Convert.ToInt32(processingReport.ProcessingSummary.MessagesSuccessful);
resultCatalogFeed.ErrorCount =
Convert.ToInt32(processingReport.ProcessingSummary.MessagesWithError);
resultCatalogFeed.StatusCode = processingReport.StatusCode;
}}
then I am getting the posting date but not getting the posting date with Time
since our client complaining about the delay in tracking update on amazon, I am unable to find out
the update time in our system, coz status response does not have that, so please help me how to get that detail.
Is anything wrong I am doing in this, please suggest. Kindly help me ASAP, Its urgent, Thanks in Advance

Note: Our client asked me to create support ticket on amazon that why we are not getting the tracking update time
in response so amazon asking us to provide all the request details url, endpoint, parameters, headers, and payload then
they will check and answer our query.
