Question

I am going to implement paypal in my iphone native app. But I am facig an issue in that.

I want to get my transaction Id regarding my PayKey. There is a direct method to get pay key in PayPal library to get PayKey but not a method to get transactionId.

Here is that method:

-(void)paymentSuccessWithKey:(NSString *)payKey andStatus:(PayPalPaymentStatus)paymentStatus;

As I am thinking IPN(Instant Payment Notification ) can help to resolve this issue but I don’t know how to implement that one in my app?

Please help me to resolve this issue.

Thanks,
Chandra Prakash
