What the Katana–ShipStation integration does

ShipStation is a cloud-based shipping and fulfillment platform. It brings orders, shipping, inventory, tracking, and warehouse operations from online stores and marketplaces into one place.

By connecting Katana with ShipStation, you can:

  • Import orders as sales orders: Each ShipStation order becomes a Katana sales order, and shipped packages are added as fulfillments with carrier and tracking details.

  • Send sales orders to ShipStation for fulfillment: When a Katana sales order reaches Ready for fulfillment, Katana pushes it to ShipStation as an outbound order.

  • Handle cancellations automatically: When an order is cancelled in ShipStation, Katana reverts its fulfillments and removes the matching sales order.

  • Import products by SKU: Katana matches ShipStation products to existing Katana products by SKU, and SKU aliases connect SKUs that don't match.

  • See stock levels at mapped locations: ShipStation stock appears in Katana as read-only external inventory at each warehouse's mapped location.
