Can't Add / Activate Authenticate App for Oauth

I am trying to add a Zoom Oauth app for use with SF/Eventspark and I can’t authenticate the app or add it to my account. When I click ADD it goes to Invalid redirect / 4700 but the redirect is 100% the correct url. At this point I have no options I can perform? What do I do. I am not a developer, but I have set up a couple zoom apps before and not run into this issue.

Hi @rahuston
Thanks for reaching out to us, I am happy to help please
Can you make sure that you are adding the Redirect URL to your Allow list as well and try again!
