# Build an Announcement Bar Extension for the Thank You page or Customer Account Pages

We are excited to announce the release of support for building announcement bar extensions on the Thank You page and Customer Account pages, including the Order Status page, Order Index page, and Profile page. The announcement bar is a new UI-extension form factor that uses prominent placement, animation, and colors to capture buyers' attention. With this feature, you can create extensions that highlight a merchant's most important tasks on the page, such as surveys, reviews, and upsells.

You can start building an announcement bar extension now using the 2025-07 version of the Checkout and Customer Accounts UI extension APIs.

For more information on building an announcement bar extension, visit the [Shopify developer documentation](https://shopify.dev/docs/apps/build/checkout/thank-you-order-status/ux-for-announcement-bar).
