Shopify’s New Checkout Extensibility

For years, customizing your checkout page on Shopify was complex and exclusively for Plus users. This would result in a sub-par customer service experience. But that’s all changed.  Shopify announced the release of Checkout Extensibility and it is breaking down barriers, giving all merchants the power to create a seamless checkout experience. In this guide, we will look at the benefits of checkout extensibility and show you how to leverage it for your store.

What is Checkout Extensibility?

Checkout extensibility is a suite of powerful platform features that make it easier to customize your checkout that’s app-based, upgrade-safe, higher-converting. Additionally, integrated with Shop Pay, which means for the first time ever, express checkout can be customized.

Coupled with this feature, you can make code-free customizations to your checkout using apps and branding tools, or use our collection of components and APIs to build more bespoke checkout experiences.

Key Features

Features include:

  • Checkout Editor
    A drag and drop interface to quickly and easily edit the look of your checkout (by adding your logo, changing the background color, updating the font etc.) and install checkout apps that add more functionality. This seamlessly integrates with Shop Pay.
  • Branding API
    Merchants can now utilize new branding tools to tailor their checkout experience.

With the branding API you can add a logo to your checkout header, change the background of your checkout form, change the background of your order summary and customize the font and colors of your checkout page.

  • Checkout UI extensions
    Customize checkout by inserting components at defined points in the checkout flow.

Consequently, whether it’s custom-made or installed from the official marketplace, Checkout Extensions offers a robust system that allows adapting checkout to merchants’ needs. Moreover, checkout extensions can adapt to style changes defined through Checkout Branding.

Some examples of extensions you can add with third-party apps are upsells, surveys, testimonials and social media links.

  • Pixels manager
    This is a new section in the Shopify admin which allows merchants to add and manage pixels that track customer events on multiple pages of your online store, such as the checkout and post-purchase pages. However, if there isn’t an app pixel available that meets your requirements, then you can use custom pixels on your store to track customer events without having to modify your theme code.
  • Components for custom apps
    Build bespoke customizations by developing custom apps with Shopify Functions, checkout UI extensions, web pixel app extensions, and post-purchase extensions.

What does this mean for Shopify Plus users?

If you are a Shopify Plus merchant, you might be using checkout.liquid to customize your store checkout. Moving forward, Shopify will be investing in checkout extensibility as the sole way to customize Shopify Checkout.

Therefore, shops that currently use checkout.liquid need to upgrade to checkout extensibility before 13 August 2024. After which the feature will be deprecated and removed. 

Upgrading requires replicating any required checkout.liquid customizations in Checkout Extensibility using the features and components available. This will likely require developer support, and potentially some custom app development.

What are the benefits of upgrading?

Upgrading to checkout extensibility comes with a laundry list of benefits including;

  • Increased conversion and speed
    Checkout extensibility is built on the latest Shopify platform technology, with 2X faster checkout interactions and page transitions that increase conversion over 1% on average.
  • Upgrade-safety
    Unlike using checkout.liquid, you never need to perform a checkout upgrade again, meaning you gain access to new checkout features as soon as they’re available.
  • Shop Pay integration
    Add any or all of your customizations to Shop Pay, creating a consistent experience for your customers while benefiting from Shop Pay’s 4X faster checkout experience.
  • Improved security
    Checkout extensibility is powered by a set of Shopify UI components and APIs that run in a sandboxed environment, allowing you to benefit from additional security.
  • New checkout functionality
    Gain access to the new features—like Shop Promise, pre-orders, and one-page checkout—when you upgrade to checkout extensibility.
