API

An API (Application Programming Interface) is a set of defined rules and protocols that allow different software applications to communicate with each other and exchange information. APIs serve as a bridge between different systems and allow developers to integrate functions or data from one application into another.

In the context of online payments, APIs play a crucial role. Payment providers such as Payrexx provide APIs that enable e-commerce websites to seamlessly integrate payment functions into their platforms. Developers can use the API to initiate payment transactions, retrieve transaction data or track status updates. This speeds up the payment process and improves the user experience.
