Hey everyone.
We’re running a long-lived Python script on an EC2 instance to pull WEM adherence metrics for our Chicago team. The goal is to keep pulling data every 5 minutes without restarting the process. I thought the Genesys Cloud Python SDK (genesyscloud v2.2.0) would handle OAuth token refresh automatically, but it doesn’t seem to be working.
After about 30 minutes of running, the script starts throwing 401 Unauthorized errors on every API call. I’m initializing the client like this:
from genesyscloud.rest import Configuration
from genesyscloud.authentication_client import AuthenticationClient
from genesyscloud.wem_client import WemClient
config = Configuration(
host='https://api.mypurecloud.com',
client_id='my-client-id',
client_secret='my-client-secret'
)
auth_client = AuthenticationClient(configuration=config)
auth_client.login()
wem_client = WemClient(configuration=config)
I’m calling auth_client.login() once at the start. The docs say the SDK manages the token lifecycle, but I’m getting this traceback:
genesyscloud.rest.ApiException: (401)
Reason: Unauthorized
HTTP response headers: HTTPHeaderDict({'WWW-Authenticate': 'Bearer error="invalid_token", error_description="Token expired"'})
Is there a specific method I need to call to trigger a refresh? Or do I need to implement my own timer to call login() again before the token expires? I’d rather not manage the token expiration logic manually if the SDK is supposed to handle it.
Thanks.
The Python SDK doesn’t actually handle token refresh for you in the way you might expect if you’re just holding onto a client instance. It’s not magic. You have to explicitly manage the refresh cycle or use a wrapper that does. The docs for genesyscloud say the PlatformClient holds the token, but it expires.
Since I work with the .NET SDK, the pattern is identical. You don’t just create PlatformClientV2 once and forget it. You have to check the IsTokenExpired property or catch the 401 and re-auth. In Python, you’re likely missing a refresh step in your loop.
Here is how we handle it in C# using HttpClient and the SDK. You can translate this logic. The key is the RefreshAccessToken call before every batch of work if the token is near expiry.
// .NET SDK pattern for token management
var client = new PlatformClientV2();
await client.AuthenticationClient.LoginAsync(new OAuthClientCredentialsLoginRequest(
clientId: Configuration["Genesys:ClientId"],
clientSecret: Configuration["Genesys:ClientSecret"]
));
// Inside your loop
if (client.AuthenticationClient.IsTokenExpired())
{
await client.AuthenticationClient.RefreshAccessTokenAsync();
}
// Now make your WEM call
var response = await client.WfmClient.GetWfmSchedulesAsync(...);
In Python, you need to call client.refresh_access_token() manually. The SDK won’t do it silently. If you are using genesyscloud v2.2.0, check if you are using the genesyscloud. module directly or the high-level client. If it’s the high-level one, it should have a refresh method.
Also, check your scope. WEM needs wfm:schedule:read and wfm:adherence:read. If the token refresh fails because the scope is missing, you get 401. Make sure your client credentials have the right permissions in the app settings.
Don’t rely on the SDK to guess when to refresh. Set a timer. If the token expires in 30 minutes, refresh at 25. It’s safer. The 401 errors are happening because the token is dead and the SDK isn’t reviving it. You have to revive it.
