Manage your Marketplace inventory
Use the Walmart Marketplace Inventory API to manage and update the on-hand inventory for items you list on Walmart.com. As a Walmart seller or solution provider, you can:
* Retrieve current inventory levels for your SKUs.
* Update item quantities by SKU and ship node.
## How it works
### Overall seller journey
In a common user journey, a seller or solution provider might complete the following Walmart flow:
1. **Item setup:** Create or register products (SKUs) with Walmart using the Item Management API.
2. **Inventory management:** Keep SKU quantities accurate using the Inventory API.
3. **Order management:** Retrieve and confirm orders, shipments, and cancellations through the Orders API.
4. **Pricing:** Adjust item prices through Pricing APIs.
### Inventory management flow
Within inventory management, a typical flow is to view your current inventory levels and then update the inventory count as needed.
There are three endpoints for managing inventory:
1. First, use **GET /cl/inventory?sku={SKU}** to retrieve the current inventory count for a given SKU.
2. Then, update the inventory using one of two methods:
1. For a single SKU update, use **PUT /cl/updateinventoryforanitem**
2. For updating multiple SKUs in bulk, use **POST /cl/updatebulkinventory**.
This two-step process, retrieving current inventory and then applying updates, ensures that you can verify stock levels before making adjustments.
