How do I push new post notifications (e.g. via webhook) to third party services?

Heyjkuchta , check out this article and see if it accomplishes what you're looking for: https://developer.khoros.com/khoroscommunitydevdocs/docs/subscribe-to-community-events

Unfortunately, it doesn't really support any filtering capabilities. You'd have to handle that on your callback URL. But you can at least get notified of new events.

I hope this helps!
