You cannot start the meeting because it is hosted by another user zoom

Hey @Endyrus, @mtutty,

The start_url in the create meeting response will work up until two hours. Once two hours has passed, you need to regenerate the start_url via the Get Meeting endpoint.

@mtutty

I have another symptom to throw into the mix. We’re doing OAuth drive-by in a pop-up to Zoom to get the auth key for subsequent API request on behalf of the starting user. I get prompted to log in much more frequently than a week or two ago (like every other time I use the feature, even if those attempts are only an hour or two apart), and I also get prompted to allow our App to use my Zoom account basically every time I create a meeting. That also didn’t used to be true.

Make sure you are using the refresh token flow and not authorizing the user each time.

Thanks,
Tommy
