Authentication

Walmart Marketplace legacy consumer ID + private key/signature credentials compound discovered Get key ↗

WM_CONSUMER.ID: <credential> /WM_SEC.AUTH_SIGNATURE: <credential>

Sign in to the Walmart Developer Portal as a Marketplace seller or approved solution provider and obtain your legacy Marketplace credentials there: WM_CONSUMER.ID, the channel type value for WM_CONSUMER.CHANNEL.TYPE, and the private key material used to generate WM_SEC.AUTH_SIGNATURE plus the current WM_SEC.TIMESTAMP. The older Item and Order Swagger specs describe this header set, while current Marketplace docs indicate Walmart is moving Marketplace APIs to OAuth 2.0 in the Authentication flow.
