Hi

I am trying to connect to the zoom API and i am keep receiving

{  
“code”: 124,  
“message”: “Invalid access token.”  
}

[https://zoom.us/oauth/token](https://zoom.us/oauth/token) is returning valid access tokens ( JWT tokens)

However, all API calls still fail with HTTP 401, code 124 ‘Invalid access token’.

Any help would be great 🙂
