Relationship with return_policy

The return_window attribute complements the [return_policy] field by specifying the exact duration of the return period, while [return_policy] provides the full policy details.

Both fields are required for complete return compliance in ChatGPT product feeds.

Minimum requirements

Note: Missing or invalid values may cause your product to be flagged as non-returnable in ChatGPT.

• Use a positive integer (e.g., 30).
• Match the same duration stated in your website’s policy.
• Clearly communicate this timeframe to customers.
• Don’t use decimals, symbols, or text (e.g., “30 days”).
• Don’t leave this field empty for returnable products.

SEO / AI Tip

Including an accurate return_window improves listing transparency and buyer confidence.
It helps ChatGPT correctly display return-eligible products and can boost conversion rates by reassuring users before purchase.
