New: Customer favorite filtering for WFS inventory and recommendations

Date: July 06, 2026

WFS inventory and shipment-quantity recommendations now have a customerFavorite indicator. You can filter inventory by customer favorite status and see the designation reflected in inventory insights and recommendations responses.

What changed

• Added: customerFavorite query parameter to filter inventory results to show only customer favorite items.
• Added: customerFavorite field in the inventoryInsights response object. You can use this to identify whether an item holds customer favorite status.

Why it matters

Customer favorite items typically drive higher conversion and visibility on Walmart.com. Surfacing this signal in inventory and recommendations data lets you prioritize replenishment for high-demand items, reduce stockout risk on top performers, and align inbound shipment planning with customer demand signals.

Next steps

• Update your inventory queries to pass customerFavorite=true when you want to filter for customer favorite items only.
• Refer to the WFS Inventory API reference and Recommendations API reference for full parameter and field details.
