Invalid redirect url (4700) when whitelisting root domain

[dilipvrk (Dilip)]

I have an app which uses OAuth authorization and it is deployed to multiple servers. Each instance of the app has its own subdomain.
For example,
https://subdomain1.topdomain.com
https://subdomain2.topdomain.com

There are over a thousand such subdomains, and it is not a static list. When a user on a site tries to authorize, the redirect url will be specific to that site, something like “https://subdomain1.topdomain.com/redirect”. Adding just “https://topdomain.com” to the whitelist was enough for OAuth redirection, and it was working till yesterday. But now I’m getting “invalid redirect url” when a user tries to authorize the app unless I give the full domain in the whitelist. That means adding each subdomain separately which is not feasible.

For now I’ve added a few full domains to whitelist for testing, but this is impacting my ability to roll out Zoom integration with my app.

Is this a bug, or a new change in behaviour?

Thanks,
Dilip

Hi DeveloperBot, that did not help as the issue I’m facing is different. I’d like someone from Zoom team to take a look please.

Hi @tommy,
We are also facing the same issue for our app “Appointy Meetings For Zoom” listed on Zoom marketplace. Users are unable to connect their Zoom account due to the following error.

“Invalid redirect: https://business.appointy.com/apps/zoom/Connected (4,700)”

This was working fine before yesterday and it stopped suddenly. We request you to please look at this issue asap.
