Restricting a specific participant to be able to join a meeting just once is not possible as you’ve described it. However, you might consider creating an instant meeting (Meet Now) via API, which will ensure that a meeting expires after it’s ended and can’t be restarted. To create an instant meeting, you would designate type 1 in your Meeting Create call.
I used Registeration required option. then user can register with my meeting . so he/she cannot share meeting url with someone. because its unique URL . i disabled MULTIPLE devices active option . .
How is my approach ?
