How to make a request to FreeKassa?

Question

PHP

I have all the data that I need to have to accept payments through FreeKassa. But I don't understand how, no matter how I try to make a request, it still says "Invalid electronic signature #5", Can you tell me how to do this? Maybe there are already such functions for php?

Answer 1

the documentation has a working code example in PHP

You can also use the ready-made wrapper https://github.com/ExenJer/freekassa-php
