A homegrown cart, an internal tool, anything with an API — the custom integration is five endpoints, one webhook, one auth header and one order shape. Woosh pulls your orders and pushes tracking back; you never poll us.
GET /woosh/v1/orders # your open orders, newest first
POST /woosh/v1/orders/{id}/tracking # we send the tracking number here
POST /woosh/v1/orders/{id}/notes # label events, for your audit trailCustom platforms pay what everyone pays: $10 a parcel, Xpresspost™ with tracking included, on the Canada Post network. The integration changes how orders arrive, never what shipping costs.
