What is checkout.liquid

Shopify’s checkout.liquid is a customizable template file that allows Shopify Plus store owners to modify the appearance and functionality of their checkout page. This file enables advanced customization, giving store owners the flexibility to tailor the checkout experience to align with their brand and meet specific business needs. By leveraging checkout.liquid, Shopify Plus merchants can add custom scripts, adjust layout elements, and integrate third-party services directly into the checkout process. This level of customization is especially beneficial for creating a seamless and branded shopping experience, ultimately leading to increased customer satisfaction and higher conversion rates.

Why Shopify deprecated checkout.liquid

In the past, Shopify offered checkout.liquid as a solution for customizing the checkout page, but it had several limitations. Customizations made through checkout.liquid were difficult to test and maintain, often leading to issues with compatibility and stability. Additionally, it was incompatible with Shop Pay, which is a crucial feature for many merchants. The use of checkout.liquid required periodic and complicated upgrades to access new features, creating a maintenance burden for store owners. Furthermore, the way JavaScript was executed outside of a sandbox in the browser made these customizations inherently insecure, posing significant security risks.

Recognizing these challenges, Shopify announced the deprecation of checkout.liquid in February 2023, shifting to Checkout Extensibility. This new foundation for checkout customization is designed to be more secure, performant, and upgrade-safe, allowing merchants to use apps for tailored customizations. By moving away from the obsolete checkout.liquid code, Shopify aims to mitigate risks that could impact businesses. The required upgrade timeline mandates that store owners upgrade their Information, Shipping, and Payments pages by August 13, 2024, and their Thank You and Order Status pages by August 28, 2025. Failure to complete these upgrades by the deadlines may result in disruptions and potential risks to the business.

What is Shopify Checkout Extensibility

Shopify Checkout Extensibility offers a faster, more secure, and better-performing alternative to the traditional checkout.liquid method for customizing checkout pages. Seamlessly integrated with Shop Pay, Checkout Extensibility empowers Shopify Plus store owners to implement advanced customizations without compromising on speed or security. This innovative feature allows merchants to achieve code-free customization and develop custom apps tailored to their unique business needs. By leveraging Checkout Extensibility, Shopify Plus merchants can enhance their checkout experience, ensuring a smoother, more efficient, and highly personalized process for their customers.

Features included with Checkout Extensibility

Here is the main features of the Shopify Checkout Extensibility.

Checkout Editor

The Checkout Editor in Shopify’s Checkout Extensibility allows merchants to effortlessly customize their checkout pages with an intuitive drag-and-drop interface. Store owners can easily edit elements such as the logo, font, colors, and background to align with their brand identity. Additionally, the editor supports the installation of apps, enabling the addition of new functionalities without the need for complex coding. This user-friendly tool streamlines the customization process, making it accessible for merchants to enhance the checkout experience and create a seamless, visually appealing, and highly functional checkout page for their customers.

Checkout Apps

Through the Shopify Checkout Editor, merchants can easily access a variety of Shopify apps specifically designed for enhancing the checkout process. These apps enable the addition of new functionalities, including UI extensions, custom logic, post-purchase pages, and pixels, all without requiring any coding. This seamless integration allows store owners to enrich their checkout experience with advanced features, tailoring it to meet their unique business needs and improve customer satisfaction. By leveraging these checkout apps, merchants can create a more interactive and personalized checkout journey, ultimately driving higher conversion rates and customer loyalty.

Shopify Pixel Manager

The Shopify Pixel Manager provides a centralized, secure solution for managing pixel tracking across your online store and checkout process. Pixels, which are pieces of JavaScript code, run on your online store, including the checkout page, to track customer behavior. With the enhanced security of Checkout Extensibility, these pixels can now track customer behavior during the checkout process more effectively than ever before. By consolidating customer event tracking into a single location, the Pixel Manager simplifies the implementation and monitoring of tracking pixels. This ensures that all customer interactions, from browsing to purchasing, are accurately and securely captured, allowing merchants to gain valuable insights, optimize marketing strategies, and enhance the overall shopping experience.

Checkout Branding API

The Checkout Branding API, part of Shopify’s Checkout Extensibility, empowers store owners to implement custom styling on their checkout pages with ease. Shopify Plus merchants can now add additional styling to their checkout pages, ensuring a seamless and cohesive brand experience. With the Branding API, store owners can change colors, font styles, and logo styles, as well as add custom images. This allows the checkout page to match the look and feel of the rest of the website, providing a consistent and visually appealing shopping experience that enhances customer trust and satisfaction.

Custom Business Logic

Shopify Functions enable merchants to implement custom business logic to validate cart and checkout information and tailor payment and delivery methods to their specific needs. With Shopify Functions, store owners can create new discount types for users, customize payment options by hiding or showing methods based on parameters like a user’s special tag, and rename delivery options offered at checkout. Additionally, merchants can create product bundles by combining multiple products into one single product with a new SKU, and adjust fulfillment rules to streamline order processing. These capabilities allow for a highly personalized and efficient shopping experience, ensuring that each customer’s journey is uniquely tailored to their preferences and needs.

Post Purchase Checkout Extension

Shopify’s Checkout Extensibility includes powerful post-purchase extensions that allow merchants to build bespoke customizations by developing custom apps using Shopify Functions, checkout UI extensions, web pixel app extensions, and post-purchase extensions. These extensions enable store owners to enhance the post-purchase experience with tailored features such as upselling additional products to the order, requesting surveys or feedback from customers who have completed their shopping experience, offering discount codes for future purchases, and encouraging users to sign up for a loyalty program or create a user account. By leveraging these post-purchase extensions, merchants can boost customer engagement, gather valuable insights, and foster long-term loyalty, ultimately driving more sales and enhancing customer satisfaction.
