Return Deadline in Days [return_deadline_in_days] Field for Product Feeds

Optional for ChatGPT

The return_deadline_in_days attribute defines the return window, expressed as the number of days after purchase during which a product can be returned.

This field replaces the legacy return_window attribute and is now the canonical format expected by ChatGPT.

It is used by AI systems to clearly communicate post-purchase conditions and reduce uncertainty during checkout.

When to use

Use this field if your store allows returns for a defined number of days after purchase.

This field is especially recommended when:

• You enable ChatGPT checkout

• You accept returns (accepts_returns = true)

• You want to clearly set buyer expectations

• [return_deadline_in_days] accepts:

  • A positive integer representing the number of days (e.g. 14, 30, 60)

Format

• Type: Integer
• Accepted values: Positive integers only
• Unit: Days
• Repeated field: No
• Schema.org property: Not applicable (AI-only field)

Examples:

Minimum requirements

• Use a positive integer greater than zero.
• Ensure consistency with your return policy page.
• Provide this field when accepts_returns is set to true.
• Do not use ranges, text, or non-numeric values.
• Do not use the deprecated return_window field.

SEO / AI Tip

Clear return deadlines improve buyer confidence in AI-driven commerce.

When return rules are explicit, ChatGPT can:

• communicate post-purchase conditions accurately,
• reduce hesitation during checkout,
• improve trust in merchant recommendations.

For best results, combine this field with:

• [accepts_returns]
• [accepts_exchanges]
• [return_policy]
