HeySummit can schedule overlapping sessions, but each simultaneous Zoom webinar needs a suitable separate licensed Zoom user. Do not assign the same connected Zoom account to overlapping webinars. Zoom does not allow one user to host multiple webinars, or a webinar and meeting, at the same time.
Prepare separate Zoom hosts
Ask your Zoom account administrator to add the users you need. Zoom's user management guide describes User Management > Users > Add Users. Navigation and licence controls can vary with the account.
Assign each user the Zoom licence and Webinar entitlement needed for their room and capacity. See Zoom's licence assignment guide. An Admin role alone does not provide a Webinar licence.
Give users the permissions needed for the connection. Do not make every user an Admin solely to run overlapping sessions. If HeySummit reports a specific REST API permission error, ask the Zoom administrator to review that error.
Connect and assign each host
In HeySummit, go to Event Settings > Integrations & Developer > External Webinar Accounts > Add Host.
Add a separate host record for each intended Zoom account. For a connection you manage, use Actions > Connect Provider > Zoom. If the host manages their own account, they must sign in and connect it.
Confirm each connection shows Active. In Content & Schedule > Sessions, open Actions > Manage Session > Broadcast.
Choose Live broadcast and Zoom, then select the correct Zoom account holder. Review the creation mode and delivery setting, then save. Repeat for the other sessions, assigning a different connected account to simultaneous rooms.
Avoid connecting the same Zoom user twice
Sign out of the previous Zoom account before connecting the next host. A fresh private browser session can help avoid cached Zoom logins. Close all private windows before starting a separate private session, and check the Zoom account shown during authorization. See how to connect your webinar account and connecting multiple accounts from the same provider for the host setup.
