What is an API?

An Application Programming Interface (API) is a set of protocols, tools, and standards used for building software applications. It defines how software components should interact with each other, providing a way for one program to communicate with another program or service.

APIs enable developers to integrate existing functionality or services into their own applications, without needing to build everything from scratch. For example, social media platforms provide APIs that allow developers to integrate social media functionality into their own applications, such as sharing posts or retrieving user data.

APIs can take various forms, such as REST APIs, SOAP APIs, or GraphQL APIs. They are typically documented with clear instructions on how to use them, including the available endpoints, parameters, and expected responses.

TAGx uses a single API integration to connect merchants with all local and global PSP’s of their choice.
