Hey @mark.santoski,
Thank you for reaching out to the Zoom Developer Forum. To clarify, while you can have several licenses under an account, they are ultimately tied to users themselves. When it comes to sharing licenses amongst users, updating a user’s Webinare feature/package will update their ability to host a Webinar.
Does the webinar license need to be applied to an account at the time of OAuth access to the webinar API endpoints in order to retrieve past webinar information?
Yes, a webinar license will be applied to the user and this can be done only once you have OAuth access to authenticate the request.
When a license is transferred between accounts does the information of past webinars travel with the license or is that retained only at the account level?
No, when a license is transferred between users the license will have no impact on the previous Webinar history of the user. Regardless of if the user still has a Webinar license, historical Webinars will be reflected under the original user’s profile.
Let me know if you have any questions.
Thanks,
Max
