After solid hours of investigation I found out that it is with the data that I get from them. I am using PHP as my language and have the following calls to catch the data I can get from the webhook:
- $_POST - only returns user_id
- $_REQUEST - only returns user_id
However when I tried this:
file_get_contents('php://input');
I got what I want and expected.
It is with the HTTP_RAW_DATA that even the global $_REQUEST variable cannot retrieve.
