FastPay Payment Gatway Integration Bundle / PHP

When I started working with the FastPay API for one of my projects, I noticed they didn't have any PHP bundles available. So, I decided to create one myself to make things more organized and easier to integrate. Feel free to use it, and thank me later.

Coded according to the company's original documentation
