Additional context
It worked fine until two days ago. After that, there are no changes, but it does not work suddenly.

Hi,

we also encountered this issue few moments back. try adding the callback url to whitelist url field. that worked for us. seems like new changes on zoom end.

I am not from zoom support, just thought of notifying what worked for us.

Same issue here, it worked fine until about two days ago. The callback URL is whitelisted in the Zoom app, both HTTP and HTTPS. Any ideas what can be wrong?

hi @rafal @Dilip_Reddy_Guda @sunyeol.lim,

Apologies for the inconvenience.

Can you please send the client ID of your app to developersupport@zoom.us?

Thanks,
Ojus

@Ojus, sent! Thanks!

@rafal

Can you check your app again? it should be fixed.

Please make sure that your redirect URI and the whitelist URL are exactly the same.

Thanks

@Ojus unfortunately, there is still the same error. Redirect URI and the whitelist URL are the same.

Hey @rafal,

Are you setting the same redirect url in the install url?

Thanks,
Tommy

Hi @tommy yes it’s the same. I even regenerated publishable URL and it still does not work.

Hey @rafal,

What url are you using for the install url? Please share so I can debug.

Thanks,
Tommy

Hi,
I am seeing the similar issue about the invalid redirect URL. Please refer to the App used for this testing at β€œhttps://marketplace.zoom.us/develop/apps/n9KSP-RKTU6o8EJx3m626w/credentials”.

5m7mvnGWTaOInNDyVHl29g this is my app id. i am also facing the same problem. can you please look into it

Hi All,
Can I get any help here. I am getting the attached message while trying to deploy the app

Hey @jinadattaraj,

Try to use an Admin or Owner Zoom user to install the app. Or you can change your permissions to match the apps scopes.

Are you still seeing the invalid redirect URL issue?

Thanks,
Tommy

Hey @sabin.analogue51,

Make sure your redirect URL matches your whitelist. What is your app name?

Thanks,
Tommy

Hi Tommy,
Thank you for your response. Our monitoring team did try with the required Admin rights to install the app. Their response is as below.

Hey @jinadattaraj,

It would be great to communicate with them directly on this thread.

Please make sure they are following the OAuth flow:

Thanks,
Tommy

Please help,
Special characters in redirect_uri will cause error
For example: redirect_uri=https://abc.com/Zoom/Auth?state=dsad13213|}
It worked fine if I changed it to https://abc.com/Zoom/Auth?state=abc
It is absolutely a bug
Please fix it

Hey @thanh.huynh,

Please try base64encoding or url encoding your state params if they include special characters.

Thanks,
Tommy
