Since you built your product based on another vendor's platform, are you concerned that they might cut off access? Do you have any contingency plans for that?
Cultivating an app ecosystem on their platform is a publicly stated goal of Zoom. Cutting off any start-up building on it would be counter-productive and lead to their competitors gaining the advantage of innovation on their platform instead.
Twitter used to say the same stuff and they cut their dev community off at the knees once they got big enough (mostly because of said community building out their feature set).
But we use everything around recording, including live streaming.
Zoom has a great team of folks in the developer forums that are really helpful. My biggest gripe would be that not everything that breaks gets documented and logged so it can be really frustrating when our service breaks b/c their webhooks are down and there is no status on their end that this is the case.
We had a list of a dozen thing we wanted them to support when they started and they are all now in there... so pretty happy w/ progress.
