how to resolve this error.
Please help me to resolve this error.
having same issue using nop 3.90, any idea on that?
I have found out the reason for this error. The problem is the plugin has a bug as it is using the authorization transaction ID to issue a refund. This happens when you configured the plugin to use "Authorization" for the "Payment Action". When a new order comes in, it will save the authorization transaction id. When you click Capture on the order, Paypal will capture the money and issue a new capture transaction id back to you. The problem is that Nop is not saving this new capture transaction ID; therefore, when you need to issue a refund later, it will send the old authorization ID to Paypal to issue the refund resulting in wrong transaction id error.
However, if you set "Sale" for the "Payment Action", you do not have this problem because you will receive only a capture transaction id because the money is automatically captured. When you click refund, it will use the correct capture transaction id to issue the refund.
here is the correct code for Capture that will save the transaction ID necessary to refund:
public CapturePaymentResult Capture(CapturePaymentRequest capturePaymentRequest)
var customSecurityHeaderType = _payPalSecurityService.GetRequesterCredentials();
using (var payPalApiaaInterfaceClient = _payPalInterfaceService.GetAAService())
var doCaptureReq = _payPalRequestService.GetDoCaptureRequest(capturePaymentRequest);
var response = payPalApiaaInterfaceClient.DoCapture(ref customSecurityHeaderType, doCaptureReq);
return response.HandleResponse(new CapturePaymentResult(),
(paymentResult, type) =>
paymentResult.NewPaymentStatus = PaymentStatus.Paid;
paymentResult.CaptureTransactionResult = response.Ack.ToString();
var paymentInfoType = type.DoCaptureResponseDetails.PaymentInfo;
if (paymentInfoType != null)
paymentResult.CaptureTransactionId = paymentInfoType.TransactionID;
(paymentResult, type) =>
