I’m using “Video SDK” on the web. After entering a session, if one party is disconnected, how to notify the other party to react. Are there any related events?  
Thank you.

Hey @freda199594

Thanks for your feedback.

If a user disconnects, other participants in the session will receive a `user-updated` event for that user with a payload containing `isInFailover: true`.

If the disconnection lasts for a long time (about 2 minutes), a `user-removed` event will be triggered, indicating that the user is no longer in the session.

Thanks  
Vic

Use the “participantDisconnected” event in the [Video](https://developers.zoom.us/docs/video-sdk/) [SDK](https://swigmenu.us/blog) to detect when a party disconnects. You can trigger a notification to the other party by listening for this event. Check the SDK documentation for specific event handling details.

First of all, thank you very much for your reply. But I checked the docs and didn’t find the “participantDisconnected” event.

Check for the “participantLeft” or “userLeft” event instead, as it may be the correct one for detecting disconnections. Refer to the latest SDK documentation for accurate event names.
