How ShipStation Connects to OC3PL
Every order, from every channel, lands in our warehouse management system. There is no manual step between a customer clicking buy and a pick ticket hitting the floor. Connecting ShipStation takes one thing from you: an API key or a one-click app install. We handle mapping, SKU matching, test orders, and go-live, and tracking numbers sync back to ShipStation automatically.
How orders sync
Direct to the OC3PL warehouse management system. ShipStation is also run by OC3PL as a hub, and serves as the backup integration path for any store that cannot be mapped directly.What connecting requires
