Cause:
The Python SDK’s OAuthClient handles refresh tokens automatically, but only if the underlying HTTP session is reused. If you are instantiating a new PureCloudPlatformClientV2 object inside a loop or for every batch chunk, you are creating a fresh session that doesn’t have the refresh logic attached to the active request context. The 401 happens because the initial access token expires, and the new client instance doesn’t know to call the refresh endpoint before sending the next request. It’s not a bug in the SDK, it’s a lifecycle issue in how the client is scoped.
Solution:
Keep the client instance alive for the duration of the export. Initialize it once outside your batch loop. The SDK uses requests under the hood, which manages the token refresh via a custom adapter. If you destroy the client, you destroy the adapter.
Here is the correct pattern for a long-running export:
from genesyscloud import PlatformClient, RoutingApi
# 1. Initialize ONCE
platform_client = PlatformClient()
platform_client.set_access_token('your_initial_token')
platform_client.set_refresh_token('your_refresh_token')
routing_api = RoutingApi(platform_client)
def export_queue_data():
try:
# This will trigger automatic refresh if the token is near expiry
# because the same session is used
response = routing_api.post_routing_queue_analytics_queuequeuemetrics(
body=analytics_request_body,
expand=['statistics']
)
return response
except Exception as e:
# If you still get 401 here, the refresh token itself might be expired
# or invalid. Check the New Relic trace for the specific HTTP status.
print(f"Export failed: {e}")
# Run your batch loop here, reusing the same routing_api instance
If you are seeing intermittent 401s even with a single client, check the platform_client.auth.get_access_token() expiration time. Sometimes the refresh happens too late if the token is already dead. You can force a refresh manually before a heavy batch if you need to be safe, but usually the SDK handles it.
Make sure you aren’t catching generic exceptions and swallowing the 401. Log the full error. If the refresh token is invalid, the SDK will raise an AuthenticationError. That’s different from a 401 on the API call.
Also, watch out for rate limiting on the refresh endpoint itself. If you are hammering the API with thousands of requests per second, you might hit the OAuth server limits. Spread the load or use the bulk endpoints if available.
Check your New Relic dashboard for the genesys_cloud_api_latency custom event. If you see a spike in 401 errors right before a successful refresh, that’s expected. If you see 401s without a subsequent refresh attempt, the client is likely being recreated.
