How Walmart Marketplace 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 Walmart Marketplace 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 inventory levels and tracking numbers sync back to Walmart Marketplace automatically.
