Zoom no longer allows for webhooks.
Make.com has published a Zoom app that, once installed on your Zoom account, allows users to connect to Zoom and do pretty much anything through their Zoom node.
I don’t use it often, but when I do, it is mission-critical. I use it mostly for webinar registration and management processes.
The current N8N Zoom node does nothing with webinars.
You can see the app here. App Marketplace
Thanks for your consideration.
