For anyone who comes to this forum post, I just want to make it clear that this is NOT true.
From Zoom Support via a support email:
“For a published app, any change to the production environment will need to have an update request. When you make a scope change, users have to reauthorize, whereas other changes can be rolled out silently. In either of the cases, it needs to be approved by our marketplace team in order for the changes to reflect.”
Zoom’s current timeline for app approval is around 7 business days after submission. This means that if you submit an application in a functionally complete state but need to make any updates to it after the initial approval (say a switchover to a different production URL) you are looking at 3 weeks of wait time, not to mention more time if zoom has any requested changes to your submission.
For anyone out there who is looking to get a Zoom integration off of the ground, give yourself a month between finishing development and the date that you think it will be live.
@tommy and @michael.harrington I would advise you to make this information much clearer in your developer helpdocs, as we went through this process with a wild misunderstanding of the timeline, caused in part by responses to our questions here.
