The REST API, and the connectors built on top of it. Every account includes a sandbox, so you can integrate end to end before a single real parcel moves.
The Waypoint Shopify app is in development. In the meantime the REST API covers the same flow: push new orders on Shopify's
orders/create webhook, and poll ?updated_since= to update
fulfilments and tracking. What it means for your shop.
