API integration refers to the process of connecting different software systems or applications through their APIs (Application Programming Interfaces) to enable seamless communication and data exchange.

For integrating a 2D payment gateway, you would typically need to integrate with payment processing APIs provided by payment gateway service providers. These APIs facilitate secure transactions between your website or application and the payment gateway. Some popular payment gateway APIs include:

1. PayPal API: PayPal provides a range of APIs to integrate their payment gateway into your website or application. This includes payment processing, refunds, subscriptions, and other related functionalities.

2. Stripe API: Stripe offers a powerful API for integrating their payment gateway. It supports various payment methods, such as credit cards, Apple Pay, Google Pay, and enables you to handle payments, subscriptions, refunds, and more.

3. Authorize.Net API: Authorize.Net provides an API that allows you to accept and manage payments securely. It supports credit card, eCheck, and a variety of other payment methods.

4. Braintree API: Braintree offers an API for seamless integration of their payment gateway. It supports multiple payment methods, including credit cards, PayPal, Venmo, and Apple Pay.

5. Square API: Square provides APIs to integrate their payment gateway and manage payments. It supports various payment methods, including credit cards, invoices, and more.

When integrating a 2D payment gateway, you'll typically work with your preferred payment gateway's API documentation and use its APIs to process payments, handle refunds, manage transactions, and any other related functionalities required for your business.

Please note that the specific APIs required depend on the payment gateway you choose. It's recommended to consult the documentation or contact support from the payment gateway service provider to get precise details on integrating their API with your 2D payment gateway.
