[Walmart](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#walmart) # Walmart: Marketplace API access - 3P Sellers ## Set up Marketplace API access for 3P Sellers to get full data insights (overall sales, units sold, ROAS). Walmart Marketplace offers two primary types of API access based on whether you are a first-party (1P) supplier/vendor or a third-party (3P) seller. The key difference between the two lies in your relationship with Walmart: 1P suppliers/vendors (including Drop Ship Vendors (DSV) and warehouse vendors) sell directly to Walmart, while 3P sellers sell directly to customers through Walmart's platform. This guide outlines the steps and processes for accessing the APIs for 3P Sellers. ### 3P Seller API Access 3P sellers list and sell products directly to customers through Walmart's online platform. The Marketplace API provides these sellers with tools to manage feeds, items, orders, and other settings. ### Steps to Provide 3P Seller API Access: 1. Click on Account Management in the bottom left corner under Global Settings. Then go to [Accounts](https://app.intentwise.com/#!/ams-admin-account-management?tab=accounts) \> Add Accounts \> *Walmart Marketplace account* and click Next. ![](https://help.intentwise.com/hs-fs/hubfs/undefined-Feb-17-2026-11-07-12-1286-AM.png?width=670&height=288&name=undefined-Feb-17-2026-11-07-12-1286-AM.png) 2.
