Shopify Checkout Extensibility: A Comprehensive Guide for Merchants

What is Shopify Checkout Extensibility?

Shopify Checkout Extensibility is a modern, more efficient alternative to the outdated checkout.liquid for customizing your checkout process. Announced in February 2023, Shopify has deprecated checkout.liquid in favor of Checkout Extensibility, which offers enhanced security, performance, and ease of updates through app-based customizations. Sticking with the old checkout.liquid code past the set deadlines poses significant risks to your business.

 By upgrading to Checkout Extensibility, you can leverage several new features:

 -Checkout Customizations: Customize your checkout, thank you, and order status pages with apps. After installing an app in your Shopify admin, you can add it to your pages using the checkout and accounts editor.

- Checkout and Accounts Editor: A tool to customize and edit the functionality and appearance of your checkout and customer accounts pages, separate from your theme editor.

- Shopify Pixels: Manage your tracking pixels with the Shopify pixels manager, which centralizes your scripts and runs them in a sandbox environment for better quality control.

- Branding API: Updates the checkout branding settings for a checkout profile.

 Checkout Extensibility allows you to create customizations built into apps that are easy to install and safe to upgrade. This framework is continuously evolving, adding new features and apps to meet your needs.


Who Can Upgrade to Shopify Checkout Extensibility?

Stores on the Shopify Plus plan can use Checkout Extensibility to add apps and advanced branding customizations that are upgrade-safe and compatible with Shop Pay.
