Trying to understand how the python SDK handles token expiration under load. We’ve got a Playwright suite that spins up sidecars to seed data via genesyscloud.platformclient. Right now the script hits a 401 after roughly 3600 seconds and kills the pipeline. The docs mention set_oauth_token() but nothing about an automatic refresh hook or client.auth_token. The SDK doesn’t expose a built-in interceptor. how do i wire up the callback to auto-renew without manually polling /oauth/token?
This is typically caused by the fact that the PureCloudPlatformClientV2 doesn’t actually manage the refresh cycle for you in the way you’re expecting. it’s just a thin wrapper around the REST calls, so when that access token expires, the client doesn’t know to go fetch a new one. you have to handle the refresh logic externally or wrap the client methods.
i usually solve this by creating a simple retry decorator that catches the 401, triggers a refresh via client.auth_settings.set_oauth_token(refreshed_token), and then retries the original request. it’s not pretty, but it works reliably for our data seeding scripts. here’s a rough sketch of what i use:
import time
from genesyscloud.platformclient import platformclient
def handle_refresh_on_401(func):
def wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except Exception as e:
if '401' in str(e) or 'Unauthorized' in str(e):
# assuming you have a refresh_token stored securely
new_tokens = platformclient.AuthSettings.refresh_tokens(refresh_token)
platformclient.AuthSettings.set_oauth_token(new_tokens.access_token)
time.sleep(1) # small pause to let auth propagate
return func(*args, **kwargs) # retry
raise
return wrapper
@handle_refresh_on_401
def get_user(client, user_id):
return client.users.get_user(user_id)
the key is updating the global auth settings before the retry. also, make sure your initial auth flow grabs both the access_token and refresh_token. if you’re only using client credentials flow, you don’t get a refresh token, so you’ll just have to regenerate the whole thing. i’ve seen teams try to patch the SDK source code to add interceptors, but that breaks every time you update the package. much safer to keep it in your own layer.
just be careful with concurrent requests. if multiple threads hit a 401 at the same time, you might end up refreshing the token multiple times. you’ll want to add a mutex or a lock around the refresh logic to avoid race conditions. i usually use a simple threading.Lock for this. also, track these failures in Datadog if you can. seeing a spike in 401s usually means your token lifecycle is misaligned with your job duration.
