Now copy & paste your client id, secret & api key to their appropriate settings in your mybb admin panel. Make sure you don't share your api key & secret with anyone.
Next you just need to setup your products on rex digital shop. When you're finished go into addons and create an addon called "Usergroup", set the type to "hidden". And in the value field you write the id of the usergroup you would like to give to the user once they buy. Then attach the addon to all your products which awards that usergroup. You can create multiple addons with the same name if you want different producs to give different usergroups.
