Important notice regarding 'My API Key'

Sellers using Walmart’s APIs to manage their business must use ‘My API Key’ to generate Client ID and Client Secret tokens and access the APIs. Sellers should not use delegated access API keys; these are only to be used when a solution provider is making API calls on behalf of a seller.

Please visit to Seller Help for additional information.

Time is running out! Upgrade to Item Spec 4.X today.

Our systems will no longer support v3.2 item setup or maintenance starting October 1, 2022. We encourage you to start this migration asap to give enough time to plan for all the changes. The new 4.X version includes new features to manage your items more efficiently and will help ensure your business remains uninterrupted!

Reminder: Ship Order Lines API updated—more shipping carriers available for selection

Sellers can now choose from an expanded list of shipping carriers when marking orders as “Shipped”. We’ve recently updated the Ship Order Lines API to reflect this change, adding a new schema for New Carriers.

With tracking supported through the subfield trackingInfo.CarrierName.Carrier, this means customers can see shipment status updates from more carriers, including:

  • Metropolitan (Metropolitan Warehouse & Delivery)
  • CN Post (China Post)
  • YunExpress

Plus, additional carriers like YRC Freight and AIT Worldwide are expected to be added by the end of the month. We’ll have more updates coming soon!

Updated International Trade Restrictions for Marketplace sellers

Walmart is firmly committed to complying with all laws and regulations in every market we operate, and we expect the same from our Marketplace sellers.

On June 24, the U.S. Department of the Treasury’s Office of Foreign Assests Control (OFAC) announced new sanctions strictly prohibiting the importation into the U.S. of gold, or product containing gold, having Russian Federation origin.

As events continue to develop, we ask that you monitor and ensure compliance with all Executive Orders, trade restrictions, and other sanctions regulations arising from the conflict in Ukraine.

Thank you in advance for your attention. Please reach out to your counsel with any questions or concerns.

Coming soon to configuration APIs: partnerStoreId

Beginning September 15, we are adding partnerStoreID and delegated access to the Partner Configurations GET Responses below:

This update will help sellers map configurations to the storeID and construct a store URL more easily.

Stay tuned to the Walmart Developer Portal for additional documentation and information.

Promotional pricing updates

Next month, we’re updating our requirements to qualify for strikethrough pricing and “Reduced Price” or “Clearance” flags. This is to enhance the promotional pricing experience on Walmart.com and help fulfill our Every Day Low Price (EDLP) promise to customers.

Here’s what’s changing:

  • The “Was Price” will be validated by the item’s offer history or sales history. It will be defined as either:
    • The 90-day median price paid by customers for the item (excluding limited time deals or other promotional prices) on Walmart.com,
    • The median price offered by Walmart or Marketplace sellers for the item on Walmart.com for at least 28 out of the last 90 days (excluding limited time deals or other promotional offers).
  • The submitted promotional price will need to be at least 10% lower than the “Was Price” to receive strikethrough pricing and a “Reduced Price” or “Clearance” flag.
  • If you submit a normal price update and offer a price that is lower than the “Was Price”, strikethrough pricing will automatically apply.

Keep an eye out for more information coming soon!
