We have implemented Zoom Video SDK in our application and it is working fine. Now we want to know how can we revoke or delete the JWT token created to join a session after a session is closed or when a participant leaves the session.

@vikassharma.re ,

The JWT token is only necessary at point of joining.  
While you can’t really revoke this token, there is a trick to making it “just in time” for security purpose.

Example if the time now is 2:00:00 pm  
I’ll set the `iat` time of my token to 1:25:00pm  
I’ll set the `exp` time of my token to 2:05:00pm

This will make sure that my token will expire 5 mins from now. You can make it even shorter if you like, by shifting the `iat` and `exp` time earlier.

Why is the `iat` in the past? This is to fulfil the requirement of min. 30 minutes difference between `iat` and `exp`.
