## Legacy POS Extensions

> Caution:
> On February 28, 2025, developers and merchants will no longer be able to view or access product recommendation, cart app, or POS link extensions in Shopify POS.

> We recommend building with [POS UI extensions](/docs/api/pos-ui-extensions) instead. Alternatively, you can [embed your app in POS](/docs/apps/build/pos/embed-app-in-pos).
