New: Vehicle details in fitment orders

Date: April 8, 2026

This release expands Walmart’s Order Management An Order API to include customer vehicle details in automotive orders. Automotive sellers can now access customer vehicle information directly at the item level in the API, making it easier to review compatibility details as soon as the order is placed.

What changed

• Added: A new vehicle information section at the item level in the An Order API response for automotive orders.
• Updated: The API now displays the same vehicle details provided by the customer at checkout.
• Impacted areas: An Order API integration for automotive sellers and order review workflows.

Why it matters

• Enables sellers to confirm part-to-vehicle compatibility earlier in the order lifecycle
• Helps teams to reduce misfits and contact customers before fulfillment.
• Reduces avoidable returns and rework, supporting stronger seller performance over time.

Next steps

• Update your An Order API to read and store the new vehicle information section at the item level.
• Review the updated API Reference Guide documentation.
