Predictive Routing 400 Bad Request on Multi-Org Campaign Creation via Platform API

Is it possible to create predictive routing campaigns across multiple organizations using a single OAuth token in a Premium AppFoundry integration? We are encountering a 400 Bad Request error when POSTing to /api/v2/routing/predictive/campaigns. The payload includes valid queue IDs and skill requirements, yet the response indicates a schema mismatch for the routingProfileId field.

“Predictive campaigns require explicit skill assignments matching the queue configuration.”

Any insights on handling cross-org campaign creation?
