Predictive Routing Queue Depth Sync from Zendesk

What’s the best way to map Zendesk ticket queue depths to Genesys Cloud predictive routing groups? I am seeing stale wait times in v2.0 when migrating from Zendesk’s static queue view to GC’s dynamic scoring. The queueDepth field in the API response does not match the old Zendesk widget data.

Take a look at at the data structure mismatch between Zendesk’s static ticket counting and Genesys Cloud’s dynamic skill-based routing logic. The queueDepth field in Genesys API v2.0 represents the count of interactions currently waiting in the queue, not the total volume of open tickets in Zendesk. When migrating from Zendesk’s widget data, the discrepancy arises because Zendesk counts all open tickets regardless of agent assignment, whereas Genesys only counts interactions that are actively waiting for an agent with the specific skill profile.

To resolve the stale wait times, you need to ensure the integration payload maps Zendesk ticket priority and age to Genesys’ predictive scoring engine rather than trying to force a direct queue depth sync. The v2.0 API expects a specific JSON structure for custom attributes that influence the routing score. If you are pushing raw ticket counts, Genesys treats them as static metadata, which does not update the real-time wait time estimator.

Here is the corrected payload structure for the external API integration to properly influence the predictive routing score based on Zendesk data:

{
 "externalId": "zendesk_ticket_12345",
 "customAttributes": {
 "zendeskPriority": "high",
 "ticketAgeMinutes": 45,
 "originalQueueSource": "zendesk_widget"
 },
 "routingData": {
 "queueId": "GC_QUEUE_001",
 "skillGroup": "support_tier_1",
 "priorityScore": 85
 }
}

By mapping the ticketAgeMinutes and zendeskPriority to the priorityScore, Genesys can dynamically adjust the wait time estimation. This approach aligns the external Zendesk data with Genesys’ internal scoring algorithm, eliminating the stale wait time discrepancies. Ensure the SBC or integration middleware transforms the Zendesk webhook data into this format before ingestion.
