How to identify a user who join the meeting by join_url, which is obtained when created a meeting?


I know join_url can be attacted with a parameter uname and it will show in the room. But the uname is not unique. Where can I put a unique id for my customers and contact the meeting participant with the person in our platform?



The unique id is necessary. I have the same requirement.


When append uname to the join_url, sometime it can work, sometime it can not work. Do you have the same problem?
