Hi @kantarci.u,
Good question, and happy to help.
To that end, if you want to add a button to your site for someone to join a given meeting, you can use the join_url format for this.
The following URL will launch a meeting in the Zoom Client:
https://zoom.us/j/{meetingId}
And the following URL will launch a meeting in the web browser:
https://zoom.us/wc/{meetingId}/join?prefer=1&un={displayName}
If you want the participant information to be included automatically when they join a meeting, we recommend enabling registration for your meeting and using the Add Meeting Registrant endpoint:
This endpoint returns a unique join_url for each registered participant, which will include details about their name, etc.
Let me know if this helps!
Will
