Payment Processing Using Authorize.Net

Building a payment gateway is crucial for any online business, especially those with eCommerce operations. Without a robust payment, gateway businesses stand to lose credibility, reputation, and customers.

So, as developers, we need to recommend and provide the best possible payment systems for the clients. In this tutorial, we will go through the process to add and enable payment transactions with Authorize.Net.

What is Authorize.Net?

Authorize.Net is a payment gateway that provides different options like SDK, API, etc., for doing payment transactions. It offers robust functions for processing payments for businesses and also supports XML and JSON variants. Today we are going to explore API payment gateway.

There are lots of API provided by Authorize.Net. Check this link for more information on the same.

The amazing feature of Authorize.Net is the staging sandbox. It is provided especially for developers to do any kind of R&D regarding payment transactions. A developer can perform unlimited payment transactions on the staging sandbox.

For that, you need to do one-time registration on their portal. After successful registration, they will provide you with three keys required to do further payment transactions. Make sure to store the keys securely.

These keys are;

  • API Login ID
  • Transaction Key
  • Key

We will explore two major options like paying through a credit card or Bank Account.

1. Charge Credit Card API

There are lots of parameters available, but we can include relevant parameters as per our requirements. Here, I am showing the required parameters specifically to pay through Credit Card.

Response:

If payment is successful, you will receive an “OK” status code and the above message as a response.

You need to save the transId (transaction ID) for future reference. This is required if the client wants a refund of that amount. At that moment, we need the system to pass that reference transaction ID with the relevant API, which is provided by Authorize.Net.

3. Credit Bank Account

This is required when we want to transfer the specified amount to someone’s bank account.

4. Refund
