I have a Joomla + Community Builder site. I want to have subscriptions via authorize.net AIM with recurrent payments. When user registers and paid he will be registered in Joomla with the special group, when the paid period expires and no recurrent payment was paid his group will be changed also to standard. Besides where can I see the API information about user's plugins?
It is all possible to do with aMember. API you can see here: http://www.amember.com/docs/html/creatingnewintegrationplugi.htm
