This is my first attempt at doing any custom coding for XenForo, so please bare with me. I have some PHP code that pulls JSON data from an API. I would like to know the proper way to setup the callback class and functions. I would like to be able to pass parameters to these callbacks to display a different set of data depending on the parameters, to minimize the number of templates and includes in the site. I am new to PHP, but have created the code needed. Just need help putting it in my forum. Thanks all in advance!! P.S. - I have searched many tutorials already, but have not found ones for all features I need.
