Connect your own tools in Settings › API and webhooks.
- API keys let a tool read your orders and products, and if you allow it, add tracking and change prices and stock. Treat a key like a password; it is shown once.
- Webhooks send events (order created, updated, refunded; return requested) to an address you choose, signed so you can check they came from us.
Zapier, Make and n8n work through their "catch webhook" step.
