Integrating Payment Gateway

What is an API?

The full form of API is Application Programming Interface. To explain in simple terms, it binds the terms of communication between the two applications and acts as the connection link between them. For example, there is a mobile application providing grocery delivery service. It would place the order, pass the order, determine delivery location, etc. All these actions and responses would use an API to do so.

When you use the app on your phone, it sends the requested data to the server via the internet. The server fetches the requested data and provides the needful response on the application via the internet. All this is possible with an API.
