Walmart's referral fees change what an order is really worth — Decionis folds the fee into margin and checks every order before your systems acknowledge it. Built OAuth-first for the Walmart Marketplace APIs; early access is opening ahead of the marketplace listing.
An 8–15% referral fee can turn a thin order negative. The gate computes fee-adjusted margin before the order is acknowledged.
Buy-box repricing that walks a listing below your floor is caught as drift, order by order.
Stock promised on Walmart that Shopify already sold — held before the promise becomes a cancellation metric.
Fee-adjusted margin clears your floor — the order is acknowledged and flows to fulfillment.
The order breaks your policy — acknowledgment waits for your yes.
Cost or fee data can't be resolved — routed to a person with the reason attached.
