Create Credential Connection

Create a short-lived browser URL for connecting an OAuth provider or reconnecting an existing OAuth credential. Open the URL in a browser, sign in as the personal API-key owner, complete provider authorization, then refresh the credentials list. A workspace API key is rejected with 403; use a personal API key.

POST/api/v2/credentials/connections

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.
