Hey @gupta.gaurabh, Good. Can you try generating a new JWT, maybe it’s expired? Thanks, Tommy ---

Hi @tommy. No luck. Can you please tell what is the exact url for List Users API I should use ? And What are the exact steps to be followed when we log in to dev account for getting API key and Secret key ? ---

Hey @gupta.gaurabh, [Here is the reference for the List Users API.](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/users) `GET https://api.zoom.us/v2/users` `"Authorization": "Bearer JWT_TOKEN_HERE"` Here is how you can get [JWT](https://marketplace.zoom.us/docs/guides/getting-started/app-types/create-jwt-app) or [OAuth](https://marketplace.zoom.us/docs/guides/getting-started/app-types/create-oauth-app) credentials.

Hey @unit1, I just tested and it worked. How are you [generating your JWT Token](https://marketplace.zoom.us/docs/guides/authorization/jwt/jwt-with-zoom)? Thanks, Tommy ---

Having similar issues. I copied the JWT token generated from the Zoom Backend (where i also find api key and secret) and also copied the example from github ([https://github.com/zoom/zoom-api-jwt/blob/master/index.js](https://github.com/zoom/zoom-api-jwt/blob/master/index.js)) But still get: { code: 124, message: ‘Invalid access token.’ } I set the JWT to expire in 90 days so its valid. I can’t get it to work. Am I missing something here? ---

I just created a new JWT app and triple checked all credentials and am also facing this error ☹ ---

Guys, I think this issue is confirmed and reported in this post [Can not create JWT app](https://devforum.zoom.us/t/can-not-create-jwt-app/11118/57). Maybe someone wants to lock this and edit the title of the other one since thats where the staff replied? ---

We faced same issue, and got “code”: 124, “message”: “Invalid access token.” Following the doc online, create JWT app with api key/secret, and generate Token for 1 week. And it never work, whether using PostMan with Bearer Token/ or using C# code with header request.AddHeader(“authorization”, $“Bearer {token}”); just wondering is anybody can help here? ---

Thanks tommy, we reactivate JWT app, and regenerate Token, that token works fine now. But if we dynamical create a token using API key/secret, and give expired for 60 minutes etc. That token still not work, we using C# JWT dotnet library ---

Hey @alan.chen, glad to hear test token is working now. Was the token working before for you when generating using the C# library? Thanks, Tommy ---
