Authenticate with OAuth 2.0 using your Walmart Marketplace client ID and client secret to obtain an access token.
Submit a price feed via the Price Feed API to update item prices in bulk; provide a list of items with `sku`, `currency`, and `amount` fields.
Enroll items in the Repricer API by calling the repricer strategy endpoint and specifying a strategy type: Competitive Price (meets Buy Box or external price), External Price (beats external site prices), or Buy Box Price (targets the Walmart Buy Box).
Set a minimum price floor and optional maximum price ceiling in the repricer strategy to prevent the automated repricing from going below cost.
Monitor results via the Pricing Insights dashboard in Seller Center, which shows Current price, Buy Box price, Competitive price, and the final automated price after strategy adjustment.
Use the Repricer API to retrieve strategy performance metrics and adjust floor/ceiling prices in response to margin analysis.
Known gotchas
Walmart's Repricer will not lower prices below the configured minimum floor, but if no floor is set it can reprice to $0.01; always configure a floor before activating a strategy.
Price feeds and Repricer strategies are separate systems; a price feed update overrides the current price, which the Repricer then uses as a starting point — the ordering of operations matters.
Buy Box eligibility on Walmart depends on price, shipping speed, and seller metrics; winning the Buy Box is not guaranteed even with competitive pricing.
