Please try ‘appKey’ in camel case. Currently you have a capital A.

Thanks,

Hi everyone,

Thanks for the post. You may follow the instruction here [https://github.com/zoom/zoom-sdk-windows/blob/master/CHANGELOG.md#new-sdk-initialization-method-using-jwt-token](https://github.com/zoom/zoom-sdk-windows/blob/master/CHANGELOG.md#new-sdk-initialization-method-using-jwt-token) to generate the JWT token. Here is a python script that could be helpful to generate the token:

```auto
    iat = long(int(time.time()))
    exp = long((datetime.datetime.today() + datetime.timedelta(days=2)).strftime("%s"))
    tokenExp = long((datetime.datetime.today() + datetime.timedelta(hours=1)).strftime("%s"))

    payload = {
        'appKey': key,
        'iat': iat,
        'exp': exp,
        'tokenExp': tokenExp
    }
    encoded = jwt.encode(payload, secret, algorithm='HS256')

```

Thanks!
