Walmart has the option for you to sell directly to consumers on Walmart.com as a 3rd party seller, or Walmart can post your products on Walmart.com, and purchase them from you when they receive an order.  If you have a Walmart Supplier Center, instead of Seller Center, you will need to have a Walmart DSV integration in Zentail.

There are a few simple steps to create this connection:

The first step is to go to your Integration Settings page in Zentail and use the Add New Integration button to add a Walmart DSV integration to your account. For detailed instructions, check out this article.

These are accessible in your Supplier Center by going to the gear icon in the top right and selecting API Credentials under the Administrator Options.  Copy and paste the Consumer ID and Private Key into the corresponding fields on your WalmartDSV integrations page in Zentail.

These are accessible in your Supplier Center by going to the gear icon in the top right and selecting Distribution Facility under DSV Settings.  In that view, you'll be able to see your different warehouses and a "Show Details" button.  Once clicking, you should see a Warehouse ID next to the name.

Copy this value and paste it into the Walmart Ship Node field on the warehouse in Zentail from the three vertical dots > Account Settings > the warehouse. 

Note: If you are adding a new distribution facility in Walmart DSV make sure you follow the help article here, and notify seller support/your buyer of your change so they can activate the ship node

Unfortunately, this is not easily visible in the supplier center,  so the easiest way to get it is to go to Manage Items (middle left) > Download (middle right) and get the Vendor ID from the downloaded excel file. Note: this should match your first Distribution Facility ID. Punch the Vendor ID into the corresponding field in the Integration Settings for WalmartDSV. 

Product data, new products, and product pricing is managed directly in Walmart.
Zentail manages the inventory and orders for those products.
