Update line items in response to changes made during checkout.

# Hosted page

> This is a Hosted page for when payment-ui is stripe-hosted. View the full page at https://docs.stripe.com/payments/checkout/dynamically-update-line-items?payment-ui=stripe-hosted.

Dynamically add, remove, or update line items included in a [Checkout Session](https://docs.stripe.com/api/checkout/sessions/object.md).

This allows you to:

- **Check inventory**: Run inventory checks and holds when customers attempt to change item quantities.
- **Add new products**: Add a complimentary product if the order total exceeds a specific amount.
- **Update shipping rates**: If the order total changes, update shipping rates by combining the method described in this guide with our guide on how to [Customize shipping options during checkout](https://docs.stripe.com/payments/checkout/custom-shipping-options.md).
- **Update tax rates**: If you’re not using [Stripe Tax](https://docs.stripe.com/tax/checkout.md), you can dynamically update [tax rates](https://docs.stripe.com/billing/taxes/collect-taxes.md?tax-calculation=tax-rates#adding-tax-rates-to-checkout) on line items based on the shipping address entered.

Dynamic updates aren’t supported for hosted pages. You can use this feature with [Elements with the Checkout Sessions API](https://docs.stripe.com/payments/advanced/dynamically-update-line-items.md).
