Checkout Extensibilitycapabilities are available for developers to start building apps for checkout customizations. We’re gradually rolling out checkout extensibility to Shopify Plus merchants so they can install and use your apps in production. Merchants will be able to discover apps with checkout UI extensions via the new checkout editor.
Checkout extensibility is uniquely designed to be secure, fast, and upgrade-safe, while working with Shop Pay, the highest converting one-click checkout on the internet. View and join apps built with checkout extensibility in the Shopify App Store - Customize Checkout collection.
Add new functionality
App developers can leverage Checkout UI extensions to add new functionality in various places in checkout and Shop Pay. Use these extensions to add in unique elements like product offers, custom fields, custom banners, and more that are adaptable to various flows, creating a unified experience for buyers wherever they choose to checkout.
Use the new Web Pixel extension to provide events list that merchants can subscribe to. Apps will be able to hook into the events in the Pixels API, including checkout, to allow merchants access privacy-compliant customer behavior analytics.
Merchants are now able to use the new Checkout Branding API to customize the styling, to truly make checkout feel like their own, adapting the visual appearance such as the logo, font, and colors. Checkout UI extensions will inherit the brand settings from this API, so your app automatically reflects a brand’s style.
If you are just getting started in building apps for checkout, you can start by reading our developer documentation on how checkout can be customized. We have provided a few resources to help developers build with these features:
