I am building an e-commerce web site and I am down to the payments options. My first task is to link up the order with the Paypal API, however i've been looking for options for a few hours and I have no clues where to start.

I have checked this: http://www.asp.net/web-forms/tutorials/aspnet-45/getting-started-with-aspnet-45-web-forms/checkout-and-payment-with-paypal But I cannot fathom where to start, especially since it is using Web forms and I am only experienced with MVC.

Can anyone help me out? Thank you very much.

    I would say the tutorial you've got there is a very good place to start. Start reading from "Integrating Paypal" The core functionality is not dependent on your choice of UI framework. – Colin Bacon Feb 21 '14 at 15:20
  • I'm reading what you have provided, @DmitryKvochkin, but for this page (https://developer.paypal.com/webapps/developer/docs/integration/direct/make-your-first-call/), I don't understand how to make the call for the Token call and Api call. I'm using C#. – hsim Feb 21 '14 at 16:08

    @HerveS if you only want to implement the paymant, that part is not important. This is the most important to understand: https://developer.paypal.com/webapps/developer/docs/classic/products/instant-payment-notification/ – DmitryK Feb 21 '14 at 16:40

Here is the idea flow you should have in mind when implementing simple paypal payment:

On your view, add paypal payment button: https://developer.paypal.com/docs/classic/paypal-payments-standard/ht_create-pps-buttons/

Now keep in mind, that the users can change the values so, you have to implement Paypal IPN Listener: https://mvcsamples.svn.codeplex.com/svn/trunk/Kona.Web/Controllers/PayPalController.cs

Inside listener logic, you verify if the payment is correct and then do what ever you have to.

If you get in trouble testing it from localhost: just check this link: Paypal Ipn integration with asp.net MVC

If you really need something MVC specific to aid your understanding of the PayPal integration then you could try this MVC tutorial.

asp net mvc paypal integration

I do believe the tutorial that you have is also very good and worth reading.

For PayPal Express try PayPalExpressCheckoutMVC-MultiItem

  • Wow, I really like that! I'm going to delve in the solution. Is that kinda like a DLL that I had to my project, or do you suggest that I rather work from the solution to implement my own things? – hsim Feb 21 '14 at 16:13
  • I would add it as a project to your existing solution, then you can create a PurchaseController in your web project using the existing PurchaseController as an example. – Andrew Feb 21 '14 at 17:26
