hi krumch!
thanks for your answer, but this solution (api/notifications &mu-plugins) on my situation had a realy bad behavior in the past(sometimes did not catch events…) .
So instead of using mu-plugins i wrote my own plugin where i use s2member hooks for all mu needs and seems to works fine.
Now i want to improve it a little and catching succesfully paypal payments (recurring or not) and do several things .
I try to find which hook is suitable for this event….
So, is there a solution to this problem or i should try anything else?
Thanks in advance!
