LiveKit Community

Hi devs! I'm using *LiveKit Cloud* and want to prevent participants from joining non-existent rooms.
My goal:
• *Host* clicks "Create Room" → room is created.
• *Participant* clicks "Join Room" → only joins if the room exists.
• Prevent auto room creation when `roomCreate: false`.
Issue:
Even with `roomCreate: false`, participants still auto-create rooms on join. Also, there's no way to check if a room already exists since `RoomServiceClient` isn’t available on Cloud.
Right now I’m tracking room names manually on the backend. Is there a better way to handle this on *LiveKit Cloud*?
Thanks!

Hi!
What do you mean by `RoomServiceClient` is not available on Cloud? You can use <https://docs.livekit.io/home/server/managing-rooms/#list-rooms|List Room API> to know whether a room exists or not

I've just run into this same issue -- a participant who has `roomCreate: false` still auto-creates a room on connecting (to livekit cloud).

It's problematic because I'm implementing a moderated room. The moderator can end the session and delete the room but the participant can reconnect and the room is recreated!

Hi!
You would have to disable this project level setting `Automatically create rooms on participant join` on the setting page and then `roomCreate` should take precedence
  


Ooh nice, thanks! I completely missed those settings.
