Acknowledge a created order

After an order is created, you need to acknowledge it in the system so that it can be processed. Walmart requires a seller to acknowledge orders within four hours of receipt of the order, except in extenuating circumstances.

To acknowledge an entire order, including all of its order lines, use Acknowledge orders API. Upon success, the API provides the acknowledged order in the response.

Note: Walmart Fulfilled orders can’t be acknowledged.

In general, only orders that are in “Created” status should be acknowledged. As a good practice, acknowledge your orders to avoid underselling. Orders that are in “Acknowledged” status can be re-acknowledged, possibly in response to an error response from an earlier call to acknowledge order.

Note: Orders with line items that are shipped or canceled should not be re-acknowledged.
