apologies I might have misstated my question…I am not asking to limit the number of registrants for a meeting/webinar…is there a way to limit the number of accesses to a registrant URL for a meeting or webinar? we are trying to limit the sharing of registrant URL to others…thank you…

Hey @sabraha5,

Yes, you can only allow the unique registrant join_url to be used once by turning off the “Allow attendees to join from multiple devices”


hey @tommy…thank you very much for the response and i see in the webinar create API ( the “allow_multiple_devices” setting…but it seems the same does not exist in meeting create API (…is there a way to allow 2 number of “access” per registrant URL…the reason being if someone has an issue on a device and switches to another device…we would want to allow that scenario? thanks…

Hey @sabraha5,

The allow_multiple_devices is not open to the Meeting APIs yet, but will be soon. You can adjust this setting on the meeting page in

As for your question, basically the allow_multiple_devices only allows the link to be used one at a time. So if the user wants to switch devices, they can simply leave the meeting and join via the unique join link using the other device and it will work. :slight_smile:


hey @tommy…thanks again for the feedback…have a nice weekend!
