How can we prevent duplicated participants in meeting?

Hi @elisa.zoom,

Thank you very much for your message. We have looked into the link that you sent, and while we’re able to see if someone already has an ongoing session (already joined the meeting), we can’t figure out how to prevent the duplicates. How does Zoom do it? There has to be a way of preventing duplicates right? We didn’t have duplicates before using the Meeting SDK, and many users joined using the web client. What is the right approach for what we’re trying to accomplish? That is, having our own embedded web client without having duplicated participants.

For more context, based on what users are reporting, we believe the duplicates happen when they get kicked out of a meeting and see this message:

Translation: Unknown error. There has been an unknown error. Try refrershing this page to join the meeting again.

Then of course users refresh the page, and the duplicate happens. How does Zoom avoid the duplicates?

By the way, we have not been able to identify what’s causing this errors, and Zoom doesn’t provide logs for them, I have another post regarding that here: Unknown error while joining or during meeting
