These applications range from simple custom information and marketing content to more complex user interface customization, such as getting additional information from buyers, product up-selling, and loyalty points redemption.

UI extensions allow you to add new user interfaces (UI) and functions for checkout, and build them into applications using the extension points, APIs, and UI components provided by Shopify.

The first UI extension point released to developers is a post-purchase extension, which is available in a public beta. These extension points allow developers and merchants to present a quotation (such as up-sell) or content to buyers on the page after purchase.

Scripts allow you to add custom server-side logic to checkout, and safely change the behavior of payment method, freight, and check-out items.
