Hi Ian
At the moment, the integration is one way. When someone subscribe for a subscription plan in Membership Pro, the data stored in his membership pro profile will be used to fill-in registration form automatically when he register for an event in Events Booking
You can also config the system so that when someone subscribe for a plan in Membership Pro, he will receive discount when registering for an event in Events Booking, too
However, if he register for an event in Events Booking, only username and password will be used for Membership Pro. None of other data will be passed to Membership Pro
Hope my answer is clear to you
Regards,
Tuan
