# About product subscription app extensions

Deprecated

Product subscription app extensions won't be supported as of February 9, 2026. You should migrate existing product subscription app extensions to [purchase options extensions](https://shopify.dev/docs/apps/build/purchase-options/purchase-options-extensions).

Product subscription extensions enable you to add new UI and functionality to the Shopify admin. You build the extensions into your app using Shopify-provided extension points, APIs, and UI components.
