Ship With Walmart (SWW) is a Walmart Marketplace service that enables sellers to purchase shipping labels directly through Walmart APIs. It provides access to Walmart-negotiated carrier rates, simplifies shipping operations, and comply with Walmart fulfillment standards.

Ship With Walmart lets sellers generate, manage, download, and discard shipping labels programmatically, integrating shipping workflows directly into their systems.
