Buy shipping

Overview

The Ship With Walmart (SWW) API is a one stop shop for sellers to buy shipping labels from top carrier services for domestic and international shipments. Our API supports purchasing labels from USPS and FedEx for domestic shipments and Yanwen and FedEx for international Seller Fulfilled shipments, at competitive prices, and with added benefits.                   

We have partnered with Yanwen Logistics to help sellers to ship from China to fulfill customer orders in the U.S at Walmart negotiated rates. Our international sellers can simply log into Walmart Seller Center to sign the terms and conditions and start shipping orders from China via Yanwen to customers in the U.S. at Walmart negotiated rates using our API.
