Especially since CH (formerly Zoom.ai) just added a group meeting booking type for webinars, group coaching, masterclasses, etc.

They have a ton of integrations and seem very open to working to with more. Here's a link to their API documentation: https://api.calendarhero.com/documentation

I posted the same request, but under their new name "CallenderHero", these 2 requests should me merged...

Yes please! Zoom.ai (now CallenderHero) is one of the most robust calendar booking tool out there! It would be incredible if you could directly integrate with them! 🙏🏽
