Customize Your Fulfillment Schedule Using the Calendar Day API

API users can now ensure an even better post-purchase experience for customers using the Calendar Day Configuration block. When you are creating or updating a fulfillment center, you can configure custom fulfillment schedules and define non-working days or shipping cut-off times.

The Calendar Day Configuration can be fetched while getting the details of a fulfillment center by passing this optional parameter “includeCalendarDayConfiguration=true.”  

For more information, read our detailed Fulfillment Center Settings guide and API reference.

New Inventory API Attribute Coming Soon

Next month we’re adding a new attribute to the Inventory APIs called, reservedQty, to help you efficiently manage your fulfillment operations on Walmart.com. The reservedQty attribute will show you the number of items that have been ordered by a customer but have not shipped from a fulfillment center. This will give you a more accurate idea of how much inventory is available to sell, so you can better determine when to replenish inventory on-hand and avoid shipping delays. 

You can reference the GET Single Item Inventory by Ship Node here, the GET Multiple Item Inventory for All Ship Nodes here, or view sample of the new Inventory API response with the addition of the reservedQty attribute below.

See How Your Items Are Performing

Use these insights to make improvements to your performance if necessary and meet the new Pro Seller Badge criteria so you can gain or retain the badge during the next cycle on October 5.
