How to integrate ASP.NET with Paypal

Are you looking for ways to integrate ASP.NET web applications with Paypal? In this article, I will give an overview in to integrating ASP.NET with Paypal to receive payments in your website using Paypal Payment Gateway.

Paypal offers a payment gateway, which can be used by online merchants to receive credit card payments. Paypal is much more than a payment gateway, but in this article, I am discussing how to use it as a payment gateway to accept credit card payments and how to integrate it with ASP.NET.

Options to accept credit card payments using Paypal in an ASP.NET application

There are several ways you can accept credit card payment and integrate with ASP.NET websites. Some of them are:

1. Create Paypal buttons in your ASP.NET website and allow users to click on them to buy one or more products or services. This approach does not require any programming knowledge. However, you have little control on how the payments are handled in your ASP.NET application. Most of the processing happens at the Paypal website.

In this approach, you will go through a wizard and create a "Buy Now" button at Paypal website. Paypal will generate some HTML script for you and you can place it in your ASP.NET web application. In fact, this can be used in Non-ASP.NET web apps too since it is plain HTML.

This is a very easy to implement method of integrating Paypal payment options in to an ASP.NET application, however, it does not give you much flexibility in terms of customization.

2. Use third party shopping carts that support ASP.NET Paypal integration. If you are ready to spend some money to buy third party services, you can go for this option. You can purchase third party shopping cart services which use Paypal as payment gateway and integrate Paypal payments in to your ASP.NET applications.

3. Custom Paypal integration with ASP.NET
If you are a developer or you have a development team, you can integrate Paypal with your website using Paypal APIs. You will have to write code to make calls to Paypal APIs through the web and have to handle the responses from the payment gateway. This is a pretty complex method and you will be responsible for various steps in the payment process including offering your own shopping cart and checkout process.

4. Paypal Express Checkout
Paypal Express Checkout is another way of accepting Paypal payments through custom integration of Paypal APIs. In this approach, you have to build all the webpages involved in the checkout and payment process. In each step of the payment process, you will call one or more Paypal APIs and Paypal will call back your web pages with some updates on the payment process.

If you give some example code then it will be better to understand rather than studying only theory.
