# Adds support for metadata in confirmation tokens

## What’s new

Adds a [metadata](https://docs.stripe.com/api/confirmation_tokens/object.md?api-version=2026-08-26.dahlia#confirmation_token_object-metadata) property to the [Confirmation Token](https://docs.stripe.com/api/confirmation_tokens/object.md?api-version=2026-08-26.dahlia) object. You can attach up to 50 key-value pairs of metadata when creating a ConfirmationToken through Stripe.js using [stripe.createConfirmationToken](https://docs.stripe.com/js/confirmation_tokens/create_confirmation_token). When you [retrieve a Confirmation Token](https://docs.stripe.com/api/confirmation_tokens/retrieve.md?api-version=2026-08-26.dahlia) with your secret key, it includes the [metadata](https://docs.stripe.com/api/confirmation_tokens/object.md?api-version=2026-08-26.dahlia#confirmation_token_object-metadata).

## Impact

If your integration retrieves confirmation tokens on the server side, you can now pass metadata key-values along with the payment details, and the retrieved ConfirmationToken returns them in the [metadata](https://docs.stripe.com/api/confirmation_tokens/object.md?api-version=2026-08-26.dahlia#confirmation_token_object-metadata) property. See [metadata](https://docs.stripe.com/api/metadata.md?api-version=2026-08-26.dahlia) for more information.
