What the Katana–Walmart integration does

Walmart Marketplace is Walmart’s ecommerce platform where approved sellers list and sell products on Walmart.com. Sellers manage items, inventory, orders, and fulfillment through Seller Center or approved solution providers.

By connecting Katana with Walmart, you can:

  • Import orders as sales orders: Each Walmart order becomes a Katana sales order that updates through later status changes, with fulfillments and tracking added as packages ship.

  • Import products by SKU: Walmart SKUs match existing Katana products or create new ones, and SKU aliases bridge mismatched SKUs.

  • See Walmart stock levels: Walmart stock appears as read-only external inventory at each warehouse’s mapped Katana location.

  • Track inbound shipments as stock transfers: Each Walmart inbound shipment becomes a Katana stock transfer that updates as stock is received.

  • Map warehouses to locations: Each Walmart warehouse syncs to its own dedicated Katana location.
