I am looking to integrate a custom api into wordpress. It so happens that I received this api (let's call it api.php for now) from a supplier and am trying to find a good way to enable the functions in a few different forms on our website.
Is it possible to integrate the api.php file in a way that I can access all functions and use them to create a few forms using gravityforms?
I appreciate all help in this. I found a FAQ that might mean this is possible but I am not 100% sure:
Thanks in advance for the reply.
