I have a PHP project which accesses an API. the project works perfectly well using the test uri for the API.
When I started using the live uri I started getting authentication errors.
After asking around and eventually finding complete documentation, I found out that the Authentication Token needs to be passed as an Http request header. The token is generated by a C# class
Short of rewriting the project in C# is there a way of making the class and it's functions available in the PHP project?
