List lead notes

Retrieve all internal notes attached to a lead, ordered oldest-first.

Notes are the same array shown in the Aura dashboard and returned inline on GET /v1/leads/:id — this endpoint exposes them standalone so partners can sync notes without pulling the full lead payload.

curl -X GET "https://api.aura-app.ai/v1/leads/550e8400-e29b-41d4-a716-446655440000/notes"
