Walmart operations span catalog, ship-node inventory, orders, and sales reports, while item content, price, and stock follow different update paths. Connect the Marketplace API through an app the brand authorizes in Seller Center, then bring available information into shared company context for AI-assisted workflows.
A direct caller uses a Client ID and Client Secret from Seller Center, under API Integration. Those seller keys grant full access. A brand connecting an app uses the consent screen instead of pasting a key into a chat.
Consent is by area: Items, Orders, Pricing and Promotions, Inventory, Returns, Account Profile, Analytics, WFS, and Shipping. A write needs full access on that area. A view-only token can read. New delegated-access keys for solution providers stopped on 30 July 2026. Keys that already existed keep working through the end of September 2026.
The seller's items, quantity at a ship node, orders, returns, and settlement files. Walmart assigns the WPID. Listing content beyond the item record comes from the spec for that product type.
Listings, stock, price, promotions, and seller-fulfilled shipment updates. Listing content is a feed, not a single-field edit. An item feed needs Items access. A price feed needs Pricing and Promotions. An inventory feed needs Inventory.
No official Walmart MCP server is part of this connection. WFS inventory is a read of units Walmart is holding. The seller does not write that record.
Bring available Walmart item, inventory, order, and settlement information together with relevant data from the rest of the business.
Last month's Walmart revenue and the change sit beside the other channels, on the same SKU.
Use connected product and sales context to prepare a marketplace update for review. Supported actions depend on account access and integration scope; advertising data is included only when separately connected.

Listing content goes out as a feed, not a single-field edit. Price and inventory are their own writes. Walmart assigns the WPID.
No official Walmart MCP server is part of this connection. The workflow described here uses the Walmart Marketplace API.
