# Adds adjustable quantity to the line items response

## What’s new

The `adjustable_quantity` property is now returned when you retrieve Line Items for [Checkout Sessions](https://docs.stripe.com/api/checkout/sessions/line_items.md?api-version=2026-01-28.clover), [Payment Links](https://docs.stripe.com/api/payment-link/retrieve-line-items.md?api-version=2026-01-28.clover), and [Quotes](https://docs.stripe.com/api/quotes/line_items/list.md?api-version=2026-01-28.clover). This property indicates the minimum and maximum quantity limits configured for the Line Item.

- `enabled` (boolean, required): Whether the customer can adjust the quantity
- `minimum` (integer, optional): The minimum quantity the customer can select
- `maximum` (integer, optional): The maximum quantity the customer can select

## Impact

The `adjustable_quantity` property is now included in all LineItem objects returned by the API. If your integration parses LineItem objects from the [Checkout Sessions](https://docs.stripe.com/api/checkout/sessions.md?api-version=2026-01-28.clover), [Payment Links](https://docs.stripe.com/api/payment-link.md?api-version=2026-01-28.clover), or [Quotes](https://docs.stripe.com/api/quotes.md?api-version=2026-01-28.clover) APIs, this property will now appear in your API responses and event payloads.
