Calendar integration is super simple. Just paste your Meetn room link (https://Meetn.com/YourRoomName) into your calendar's "Other Meeting Location" or "Default Meeting Location" field (or equivalent) and that's it. All your meetings will be in the same room, so that makes it super simple to join. (you won't have to find the link every time).
To protect your meetings from people who know your meeting room link, just turn on your Waiting Room in the Attendees panel.
We do plan to add the webhooks needed to do custom meeting URLs in the future, but we don't have a timeline on that yet.
