Moving from Zendesk tickets to Genesys interactions is exciting, but the API is blocking the flow. Getting a 400 Bad Request on POST /api/v2/interactions. The payload maps Zendesk ticket fields to GC attributes, but GC rejects it. Error says Missing required field: type. Tried setting type to digital, still fails. How do you properly format the initial interaction creation request to mimic a Zendesk ticket submission?
