We’re hitting 401 Unauthorized on /api/v2/users/me right after a successful token refresh. The access token looks valid, but the platform rejects it. We suspect clock skew between our Terraform-managed infra and Genesys. Is there a way to force re-auth or check token validity locally before the call? Here’s the Python snippet:
Clock skew is the usual suspect here, but before you start blaming your server’s NTP config, check if your Python SDK is actually caching the token correctly. The PureCloudPlatformClientV2 client handles refreshes automatically, but if you’re manually managing the OAuth flow or using a custom wrapper, you might be sending an expired access token while the refresh token is still valid.
Here’s how to verify the token validity locally without hitting the API. You can decode the JWT payload to check the exp claim. If the difference between the current time and exp is negative (or within a 30-second buffer), the token is dead.
import jwt
import time
def check_token_validity(access_token, leeway=30):
try:
# Decode without verification since we just want the payload structure
# In production, verify the signature if you have the public key
payload = jwt.decode(access_token, options={"verify_signature": False})
exp = payload.get('exp')
if not exp:
return False
current_time = time.time()
# Add leeway to account for minor clock skew
is_valid = (exp - current_time) > leeway
return is_valid
except Exception as e:
print(f"Error decoding token: {e}")
return False
# Usage
if not check_token_validity(current_access_token):
print("Token is expired or about to expire. Force a refresh.")
# Trigger your refresh logic here
If the token is valid locally but Genesys rejects it, the issue is definitely clock skew exceeding the allowed tolerance (usually around 30-60 seconds). Genesys Cloud servers are strictly NTP-synced. If your infrastructure is drifting, you need to tighten your NTP configuration on the host running the Python script.
Also, make sure you’re using the genesyscloud_authentication provider in your Terraform setup correctly if this is part of a larger IaC pipeline. Sometimes the state file holds onto old credentials if not refreshed properly. But for the Python script itself, forcing a re-auth is as simple as calling platform_client.login() again or clearing the cached token if you’re managing it manually.
Don’t forget to check the Retry-After header if you’re hitting rate limits during the refresh storm. It’s easy to get yourself blacklisted if you’re aggressively retrying 401s.
