{"code": 124, "message": "Invalid access token." } iOS example

I’m trying to get Token and ZAK to start new meeting without a login user, following documentation (https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/start-join-meeting/api-user/authentication), but when I try to get these values, I get the same response: 401, {“code”: 124, “message”: “Invalid access token.” }

This is my Request:

https://api.zoom.us/v2/users/token?type=token&access_token=< token >

Can you help me with this issue?

Thanks in advance

Hi @rob.gomez.mu which authentication method are you using? If you are using JWT, you will only be able to get tokens for users on your account. If you are using OAuth, have you created an OAuth app with the required scopes to access user data?
