This API is used to create customer fulfillment orders by the seller for Walmart Multichannel Solutions flow. The WFS Inventory API is a prerequisite for using the Create Customer Order for WFS API. It ensures you have accurate, real-time inventory data before placing or managing orders.
The Create Customer Order API will check the delivery promise before placing an order, helping you identify and resolve potential order creation issues upfront—aligned with error descriptions shown in Seller Center.
