Please checkout my post here:

> Hey @Nad, Let me know if this helps explain things: The Redirect URI needs to be the same URI from the authorization (install URL) through to the Get Access Token request. So with these URLs set: When I go to install the app from the “Activation” page, it defaults the redirect URI to the one specified in the “Redirect URL for OAuth” input: https://zoom.us/oauth/authorize?response\_type=code&client\_id=ztmR8sxaSBGZ66b5laR7Ag&redirect\_uri=https://zoom.u…

If that does not help, please share your the redirect url you are using so I can help debug.

Thanks,  
Tommy
