Predictive Routing 400 error mapping Zendesk SLA

  • Struggling to figure out why the routing strategy fails when trying to replicate Zendesk SLA-based prioritization in Genesys Cloud Predictive Routing.
  • The POST request to /api/v2/routing/predictiveroutings returns a 400 Bad Request with the message: ‘Invalid value for priority calculation method’.
  • We are attempting to map high-priority Zendesk tickets to specific agent skills, but the GC API rejects the configuration payload entirely.
  • Environment: Genesys Cloud EU (Frankfurt), Admin Console v2.45, migrating from Zendesk Support Professional.
