Walmart Marketplace integration: orders, labels, stock and settlements in one operation
Walmart orders, buyer cancellations, Buy Shipping labels, stock, price and handling-time sync, returns and settlements, running alongside Amazon, eBay and Shopify with the same stock pool, the same order screen and the same profit math.
Nobody runs only Walmart. Every Walmart seller also sells on Amazon, runs at least one own store, and ships from a real warehouse, so a Walmart connection is worth what it ties into, not how it looks in Seller Center.
Connect with the API keys from Walmart Seller Center, and Walmart orders land in the same screen as every other channel. Each part of the integration has its own page below.
What you can do
Orders and buyer cancellations
Orders pulled in automatically and acknowledged for you. A buyer cancel is auto-approved, or put On Hold for you to keep or cancel, and a shipped order is never touched.
Walmart Buy Shipping on the order screen
Walmart’s own UPS, FedEx and USPS rates next to your carrier accounts, and the tracking goes back to Walmart automatically.
Stock in lockstep with every other channel
On Pro, sell three on Amazon and the Walmart quantity drops by three, and the other way round.
Price and handling time
Prices go to Walmart one by one or in bulk feeds, and handling time goes through its own feed, the way Walmart requires.
Listings by GTIN or UPC
Offer your product against an existing Walmart catalog item by GTIN, UPC, EAN or ISBN, and pull Walmart’s title, description and images into your product.
Settlements matched to every order
Walmart’s reconciliation report matched to your orders every day, so profit per order uses what Walmart actually charged.

Frequently asked questions
How do I connect Walmart to Rilk?
Create API keys in Walmart Seller Center, paste the Client ID and Client Secret into Rilk, and switch Walmart on. Orders start coming in on the next pull.
Does Rilk work as a warehouse system for Walmart Marketplace orders?
For most sellers, yes. On the Pro plan Rilk runs warehouses and bins, pick lists, and label printing — the fulfillment layer behind your Walmart orders, in the same flow as Amazon and eBay orders.
Is Walmart Buy Shipping included?
Included, on every plan. Rilk shows the Walmart Buy Shipping rate alongside your own carrier rates, filtered to the services that still make the promised delivery date, and the tracking number goes back to Walmart automatically.
Can I buy UPS labels through Walmart Buy Shipping?
Yes. Walmart only accepts a UPS label bought through Buy Shipping when the request names your ship node, the Walmart ID of the warehouse the box ships from. Leave it out and Walmart refuses the label with "ShipNode id is mandatory for UPS carrier." Rilk resolves it for you: the ship node you picked on the order, else the one linked to the order’s warehouse, else your default ship node.
Can I run more than one Walmart seller account?
Yes, on Ultimate. Each Walmart account connects as its own company in Rilk, with its own listings, orders and settlement reconciliation.
