I’m curious as to why the Genesys Cloud Data Action is returning a 422 Unprocessable Entity when attempting to update a user’s queue assignment through the Predictive Routing API? The integration is designed to automatically adjust agent availability based on ticket priority in ServiceNow, but the webhook payload is being rejected by the /api/v2/predictiverouting/users/{userId} endpoint.
The ServiceNow REST API is successfully triggering the Genesys Data Action, and the initial authentication via OAuth 2.0 client credentials is functioning correctly. However, the subsequent PUT request fails during the payload validation phase. The response body indicates that the queue_id field is invalid, despite the ID being pulled directly from a validated Genesys Cloud Queue resource. The payload structure matches the documentation precisely:
{
"queue_id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"status": "available",
"priority": 1
}
Cross-referencing the Genesys Cloud API documentation for Predictive Routing, the schema appears correct. The issue persists even when testing with static values that have been verified in the Architect UI. Furthermore, the same Data Action works flawlessly for updating user status to offline, suggesting the problem is specific to the queue assignment logic or a subtle schema mismatch in the nested object.
The environment is running on the London region, and the ServiceNow instance is on the Paris data center. Latency is negligible, so timeout issues are ruled out. The error log in ServiceNow shows the Genesys webhook returning the 422 status with a message stating “The request body was not well-formed.” This is contradictory given the JSON validity.
Is there a known issue with the Predictive Routing API rejecting valid queue IDs via Data Actions? Or is there a specific header requirement for this endpoint that is not documented in the standard Data Action setup guide? The integration is critical for our real-time workforce management, so any insights into the exact validation failure would be greatly appreciated.
