I found this thread from 2001 but not sure if it has the exact situation I have “Thank you for reaching out to the Zoom Developer Forum. We don’t support rescheduling meetings that have already occurred. Instead, you can use the information from the old meeting along with the Create a Meeting API in order to schedule a new meeting in the future.”
Our scenario is a single non-repeating meeting has a start time in the past. But no one ever started it. So now we want to reschedule. We want to use the PATCH Zoom Meeting API to start the start time from a part datetime to a future datetime. The prior threat makes a comment about a meeting already occured but don’t know if that means they were started in the past or simply have a start time in the past even if never started. I didn’t see any not about that in the document on PATCH other than that the new start time must be in the future.
