500 Internal Server Error during App Authorisation

I am having the 500 Internal Server Error when I launch the App Authorisation using OAUTH2 app in order to get access token. My email and password are correct(can be signed in at Zoom), and it is the same email as the developer email field in Zoom OAUTH2 app. Th redirect uri are the same too.


Which App Type (OAuth / Chatbot / JWT / Webhook)?
I am using OAUTH app

Which Endpoint/s?
This is the url/ the API that I am using ‘https://zoom.us/oauth/authorize?response_type=code&client_id=XXXXX&redirect_uri=$zmEncodedWSurl

How To Reproduce (If applicable)
Steps to reproduce the behavior:

var url ='https://zoom.us/oauth/authorize?response_type=code&client_id=0C4XBizXRNaLaoAs1BENw&redirect_uri=$zmEncodedWSurl';
final callbackUrlScheme = 'foobar';

final result = await FlutterWebAuth.authenticate(

 url: url, callbackUrlScheme: callbackUrlScheme);

I’m seeing this as well. Surprised no mention on https://status.zoom.us/ - seems to be an issue on Zoom’s end.

Yeah, I think so as I have been stucking at this for days

Hey @okzoomer, @gohsyang,

We are aware of this issue, it will be fixed this weekend.

Current work around is to login first here: zoom.us/signin and then go back to authorize the app.

Apologies for the inconvenience,

Hi Tommy,

Am new to using Zoom APIs and first blocker is in OAuth itself. I’m using Postman to try the APIs and in token generation process get 500 internal server error. I am already logged into Zoom using both Chrome and Safari, not sure how to implement above recommended workaround in Postman. Will appreciate help.

We are also facing the same issue 500 internal server error for correct userName & password, please update us once it’s fixed.

Hey @AkshatSinghal, @integrationAnywhere,

This OAuth issue should be fixed, I tested and it worked.


We also confirmed the fix for OAuth issue, its working fine. Thanks for the update.
