• Root Planner - POST /api/v1/webhooks/rootplanner receives route creations/updates (route, driver, vehicle, stops) and DELETE /api/v1/webhooks/rootplanner/<routeId> removes a route. Requests must carry the header X-RootPlanner-Secret matching the Webhook Secret on the Root Planner card; otherwise Sprwt answers Unauthorized Webhook (or Webhook Secret Not Configured if you have not set one).
• Shippo - the Webhook URL shown on the Shippo card (/crons/shippo_webhook?ck=<key>) receives tracking updates; paste it into Shippo's API settings. The key is generated automatically the first time you open the card.

Sprwt does not currently send outgoing webhooks for orders or customers to third parties; use Klaviyo/KLCT events or Sprwt Emails flows for real-time reactions, or poll the API.
