Hello @jayanthee365
If any Zoom account has multiple verified and active users, and each of those users has their own (unique) meeting, then yes those unique meetings for each user can run concurrently.
If you mean, can I have one user that hosts multiple, unique meetings concurrently, then NO, this is NOT supported.
We do allow creating n-booked meetings for a single user (either via the Client, Portal, or Zoom REST API), but that single user can ONLY ever be in (as a host or as a participant) ONE single meeting concurrently (so they’ll have to leave one to join another).
Does this answer your question?
