Hi @briceicle,
Welcome to the Zoom Developer Community.
There is no limit on the number of concurrent meetings you can schedule. But you can only host one meeting at a time. For more details, please visit here: https://support.zoom.us/hc/en-us/articles/206122046-Can-I-Host-Concurrent-Meetings-
We had a similar request from one of our users previously, and here is a workaround that I recommended him. Let me know if this works in your case: Host multiple concurrent 1-1 chats without user registration
Let me know if this helps.
Thanks,
Ojus
