# Adds subscription metadata support to invoice previews

## What’s new

Adds the ability to pass [subscription_details.metadata](https://docs.stripe.com/api/invoices/create_preview.md?api-version=2026-07-29.dahlia#create_invoice-subscription_details-metadata) when creating [invoice previews](https://docs.stripe.com/api/invoices/create_preview.md?api-version=2026-07-29.dahlia). This lets you include subscription metadata as part of a preview request, whether you’re previewing a new subscription creation or an update to an existing subscription that sets or changes `metadata` on the subscription.

## Impact

If your integration previews invoices before creating or updating subscriptions that include [metadata](https://docs.stripe.com/api/metadata.md?api-version=2026-07-29.dahlia), you can now pass that `metadata` in the preview request to get an accurate preview of the resulting invoice.
