Walmart Marketplace integration

Pull Walmart.com marketplace orders into UltraCart for fulfillment and report shipments back to Walmart with tracking.

The Walmart Marketplace integration lets you sell on Walmart.com while picking, packing, and shipping from UltraCart. Orders placed on Walmart.com import into your UltraCart account, and when you ship them, UltraCart reports the shipment and tracking number back to Walmart.com.

Walmart Marketplace opens Walmart.com to third-party sellers, putting your products in front of one of the largest retail audiences online. Your listings, pricing, and product content stay in Seller Center on Walmart.com, where Walmart expects them.

Running Walmart as a separate island means a second order screen to check, a second place to type tracking numbers, and inventory that only reconciles when someone remembers to do it. Connecting it to UltraCart puts those orders in the queue your team already works, and the shipped status flows back without anyone logging into Seller Center to close it out.

UltraCart decides which of your shipping methods fulfills each Walmart.com order. You map Walmart's service levels to your UltraCart methods by priority, and UltraCart picks the highest priority method that is available, then the least expensive. You can skip historical orders with a start date, ignore specific Walmart item or order ids, and import every order as a purchase order when your accounting calls for it. If an order transmission fails because an item is missing, UltraCart retries pending transmissions hourly once the item exists.

Walmart Orders in One Queue: Walmart.com purchases import into UltraCart and ship through the same workflow as every other order.
Shipped Status Reported Back: UltraCart sends the shipment and tracking number to Walmart.com when the order goes out.
Priority-Based Shipping Selection: Map each Walmart service level to your own methods, and UltraCart chooses the best available one per order.
Import Controls: Set a start date, skip specific item or order ids, or import every order as a purchase order.
Hourly Retries: Transmissions that fail on a missing item are retried every hour, so fixing the item is all it takes.

Walmart.com FAQ.

Does UltraCart list my products on Walmart.com?

No. This integration does not create or edit listings. You manage products in Walmart Seller Center, and UltraCart handles the orders and shipments.

Why is there no Walmart tab in the UltraCart item editor?

Because UltraCart is not listing products on Walmart.com, there is no listing data to map on the item. Product content lives in your Walmart account.

Does UltraCart send tracking to Walmart.com?

Yes. As soon as a Walmart.com order is marked shipped in UltraCart, the shipment update and its tracking number go back to Walmart.

How does UltraCart choose a shipping method for Walmart orders?

You map each Walmart.com service level to one or more UltraCart methods with priorities. UltraCart picks the highest priority available method, then the least expensive.

What happens if an order fails because an item is missing?

Create the missing item in UltraCart. Pending order transmissions are retried automatically every hour, so there is nothing to resend by hand.

What do I need from Walmart to connect?

Your Walmart.com Client ID and Client Secret, found in Seller Center under Settings, API, then Consumer IDs and Private Keys.
