Webex Meetings API URL block

[ArthurFalcucci79078]

Hello everyone, 
I'm in a big need of the community. Here in our company, we are developing an integration with the WebEx Meetings API(XML), and we are facing a problem that we couldn't solve by support. API, XML, WEBEX, meetingsAPI, XML, WEBEX, meetings

The problem is: In our LMS, the costumer gonna click the activity, and then, will be redirected to the URL that the API send to us, that should be something like this: 

<meet:joinMeetingURL>https://isat-8ac2.my.webex.com/isat-8ac2.my/m.php?MTID=mc46bcce2d62a2e0692b71d9114a5126e</meet:joinMeetingURL>


But, after the redirect, the user can simply copy the URL and send to someone else.

What I would like to know is, that are any chances, to we block somehow, the url, that, even if the user copy and send to someone else, only the ones redirected by our system could access the meeting.

Thanks a lot already.
