Data Action 403 Forbidden: ServiceNow REST API Token Refresh Failure in Architect Flow

Administration

How should I properly to handle OAuth 2.0 token expiration for ServiceNow integrations when using Genesys Cloud Data Actions within a high-volume Architect flow?

We are experiencing intermittent 403 Forbidden errors when the Data Action attempts to create incidents in ServiceNow via the api/now/table/incident endpoint. The integration was stable for three weeks, but since the UTC 03:00 maintenance window on Tuesday, we have seen a 15% failure rate during peak inbound call volumes.

Environment Details:

  • Genesys Cloud: v24.2
  • ServiceNow: Washington DC (Patch 11)
  • Integration Pattern: Genesys Data Action → ServiceNow OAuth 2.0 (Client Credentials Grant)
  • Architect Flow: Inbound Voice → Screen Pop → ServiceNow Incident Creation

The Data Action is configured with a static access token that has a 1-hour TTL. We assumed the Data Action would automatically refresh the token if it expired, but the logs suggest otherwise. The error response from ServiceNow is:

{"error":{"message":"Access denied. The provided credentials are invalid or expired.","status":"403"}}

Steps to reproduce the issue:

  1. Trigger an inbound voice call that routes to a specific queue.
  2. Ensure the call connects to an agent and the Architect flow proceeds to the ‘Create ServiceNow Incident’ Data Action.
  3. Wait for the initial access token to expire (approx. 60 minutes after flow initiation).
  4. Observe the Data Action failure in the Architect flow logs.
  5. Check the ServiceNow audit log for a corresponding 403 error.

I have reviewed the Genesys Cloud documentation on Data Actions and ServiceNow integration. The docs mention that the Data Action uses the stored credentials to authenticate, but they do not explicitly state whether token refresh is automated or if a custom token refresh flow is required.

Is there a recommended pattern for handling token expiration in Data Actions? Should we implement a custom OAuth flow in ServiceNow to return a new access token, or is there a configuration setting in Genesys Cloud that we are missing? Any insights from others who have deployed similar high-volume integrations would be appreciated.
