Inventory

get
https://marketplace.walmartapis.com/v3/inventory

Retrieve the current inventory for a single SKU.

• If you do not add the shipNode query parameter, Walmart returns the quantity at your default ship node.
• Add shipNode to see stock at a specific fulfillment center.

Use this call to confirm stock before you accept or ship orders. The response shows the number of units available to sell (amount), the unit of measure (EACH), and the date the inventory becomes available if you set one.
