Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
Hm, so far I didn't see any of our customer use this ohanna event integration with Easysocial yet, so I couldn't confirm with you whether this is possible or not.
It would be best if you can consult with Ohanna developer regarding this and see whether they have any app or plugin can integrate with our Easysocial extension.
