Hello, Zoom support.
Domain validation was introduced recently as a part of app submission process. One of the URL addresses that our product owner has submitted while provideing necessary data for validation actually refer to Amazon infrastructure - it’s actually Webhook callback URL where we receive events from Zoom. We would like to apply for manual verification of this web address - or get some more info from your side about this setup and things we could undertake in order to move on with our submission.
Best regards,
Predrag Dukanac
