OAuth 2.0 authorization

The Walmart Marketplace app store authorization workflow incorporates an industry-standard OAuth 2.0 token-based authorization and authentication. The OAuth protocol enables our seller to grant a third-party application access to a seller’s protected data resources on Seller Center.

This token-based authentication process reduces the number of required headers per API call and allows an easy integration with Walmart APIs.

Authorization workflow

This section illustrates the authorization workflow with a diagram and detailed descriptions of each step as a seller goes through an application connection process.

This diagram explains the authorization process between the Walmart app store on Seller Center and Authorization servers:

A Walmart seller visits the Walmart Marketplace app store page within Seller Center. A later version of the app store will be accessible outside of Seller Center to enhance the discovery opportunity for prospective Walmart sellers.
