Create Knowledge Connector

Validate and connect an external source, then queue its initial synchronization. The apiKey field is write-only and is never returned. A workspace API key is rejected with 403; use a personal API key.

POST/api/v2/knowledge/{id}/connectors

Authorization

apiKey
X-API-Key<token>

Your Sim API key, personal or workspace-scoped. Generate one under Settings, then API Keys. Operations that reject workspace keys say so in their own description.
