Running a batch job to pull interaction history via the Python SDK. The job hangs for 45 minutes. Access tokens expire after an hour, so I expected the SDK to auto-refresh. Instead, I get 401 Unauthorized on the 46th API call. I’ve set refresh_token in the config and handled TokenExpiredError manually, but the callback isn’t firing. Here’s the snippet:
client = gen_cloud_client.create('authentication')
token = client.post_authentication_login(...)
# ... processing loop ...
Is the SDK not persisting the refresh token across loop iterations? Why does the automatic retry fail?
The SDK doesn’t handle the token refresh callback the way you’re expecting if you’re instantiating clients separately. The gen_cloud_client.create('authentication') call creates a new instance that doesn’t necessarily share the same token manager state as your previous calls, especially if you’re batching them in a loop. You need to stick to a single platformClient instance for the duration of the job.
Here’s how I usually wire this up in Python to avoid the 401 mid-stream:
from gencloudclient import gen_cloud_client
# Initialize the client once
client = gen_cloud_client.create('platform')
# Set credentials
client.login(client_id='your_client_id', client_secret='your_client_secret', environment='mypurecloud.com')
# Use the same client instance for all subsequent calls
# The SDK manages the refresh token internally here
analytics_client = client.analytics
# Your batch export logic
export = analytics_client.create_analytics_export(...)
The key is not calling create('authentication') repeatedly. If you do that, you’re spinning up fresh auth contexts that might not pick up the refreshed token from the parent platform client. Also, check your client_secret in your Terraform state file. If it’s drifted or rotated without updating the environment variable feeding the script, you’ll get auth failures that look like token expiry.
Make sure your environment variable for the secret is actually being pulled correctly at runtime. I’ve seen scripts fail because the secret was masked in the state but the runtime env var was stale.
