New Order and Auto-Cancelled Order Notifications

To help you improve your order management and fulfil your orders on-time with efficiency, we bring to you Order Status Webhook Notifications. You can now receive automated notifications when a new purchase order is created for you or when your order line is auto-cancelled by Walmart.

To begin getting order notifications, you should first create a Webhook subscription for Orders events (as per details given below). As soon as you subscribe for New Purchase Order notification, Walmart will begin sending you a Webhook notification payload whenever a new purchase order is created. And if you subscribe to Auto-Cancelled notification, Walmart will send you a notification when your purchase order line is auto-cancelled by Walmart. Auto-cancellation is done if order line is not updated to Shipped status with a valid tracking number by Estimated Ship Date (ESD) + 8 calendar days (Refer the KB article here for details).
