Walmart has released a new process for Suppliers to submit inventory updates for pre-order items. This enables suppliers to manage pre-order thresholds and quantity levels directly using our API’s. Pre-order volumes will be defined by the inventory levels suppliers currently have and plan on receiving prior to the release date.

What has changed?

Suppliers can now manage in transit inventory for items using our new Bulk Inventory Feed schema, providing the in transit quantity and in transit arrival date for inventory
Suppliers can see all inventory levels, including on hands and in transit, using the bulk inventory report
There are no changes made for managing non-preorder items, or managing using on-hands inventory.

1. Walmart has changed the primary identifier used for inventory updates from the stockkeeping unit (SKU) to the global trade item number (GTIN).
   • POST requests: Global trade item number (GTIN) will be the only primary identifier accepted.
   • GET requests: Both stock-keeping unit (SKU) and global trade item number (GTIN) will be supported when reading inventory levels.
2. POST Update Bulk Item/Node schema update: A new version (v2.X) was implemented with a flattened request structure resulting in an improved processing time.
3. New GET Single Item/Multiple Nodes read request: This request enables the user to view inventory levels for a single item across many ship nodes. This includes two new attributes in addition to on-hand inventory: reserved inventory for customer orders and the inventory amount that is available to sell.
