Walmart Seller app
The Walmart Marketplace API provides resources for seller applications to manage items, orders, prices, promotions, inventory and reports on Walmart.com. OAuth 2.0 is the industry standard for token-based authentication and authorization for APIs. In this guide we’ll show you how to generate these API credentials in the Developer Portal.
How does it work?
If you want to use Walmart's APIs to manage your business, you need a Client ID and a Client Secret to access the APIs and you’ll need these credentials to generate a token for every API call.
Additional guidelines
Step 1 – Get started

Step 2 – Redirect to the developer portal
Next, select the API Key Mangement button. This will automatically log you into the Developer Portal using your Seller Center credentials.
