My Paypal REST API .NET Starter Kit

Posted in: ASP.NET

I've just completed working on a site that required PayPal integration to carry out credit card payments, using PayPal's REST API interface. I did find some aspects of the implementing PayPal's REST API a little confusing and there seemed to be a blurred line on what is the best approach. This is probably due to the vast number of .NET examples provided in PayPal's own Github repository.

I decided to create my own PayPal REST API .NET Starter kit, by combining my own efforts together with PayPal documentation and code examples from other developers online. Feel free to fork it from my Bitbucket repository: https://bitbucket.org/SurinderBhomra/paypal-.net-starter-kit.

The PayPal REST API .NET Starter kit contains everything you need to make a start in making your first card payment. It encompasses a very basic form to enter test transactions, as well as the following Nuget package references:

  • log4net
  • Newtonsoft.Json
  • PayPalCoreSDK
  • RestApiSDK

All you'll need to do is create is a PayPal Client ID and Secret, build the solution and away you go. Every time you make a transaction, a "PaypalPayment" object is returned, containing useful information to be used at application level if the payment was a success and if not, the full error information.

A successful transaction will generate the following invoice to the user's PayPal account:

I am using my PayPal Starter kit as a foundation to build upon if I ever get the opportunity to develop more features, such as refunds.

Feel free to modify my code and (even better!) add more features.
