Verify paypal payment using C#

问题:

I'm quite new to PayPal integration.

Currently I'm working on a mobile app that allows me to make payment to my merchant. However, after making a payment using the app, the transaction is reflected as "pending". I've read in some places I am required to verify the payment.

I've don't quite understand how it works, because I need to write it in C# however most of the documentation requires me to do a cURL command.

Any place or documentation that allows me to get started with the verification of payment?

Any help would be greatly appreciated, thank you!

PayPal has an officially supported .NET sdk for anything you need to do server side. Here are samples

I use the IPN (Instant Payment Notification) from Paypal and used this site as a base for my code. The PayPal developer site has plenty of tips, you just have to apply the logic C#, where there isn't a code example.

Another Controller is available on https://mvcsamples.svn.codeplex.com/svn/trunk/Kona.Web/Controllers/PayPalController.cs
