Apps in checkout
Merchants use Shopify checkout to accept orders and receive payments wherever they sell online. You can augment Shopify checkout with new functionality by building an app.
How it works
Anchor link to section titled "How it works"After a customer adds products to a cart, they use Shopify checkout to enter their customer, shipping, and payment information before placing the order.
Developers can create apps that extend Shopify checkout to include functionality that isn't provided natively. For example, you can create an app that offers a customer free shipping or other discounts depending on what's in their cart.
Merchants install these apps on their store in the Shopify admin. In the Shopify admin, merchants can use the checkout editor to place a checkout UI extension in the checkout experience.
Customization options
Anchor link to section titled "Customization options"You can customize Shopify checkout using multiple technologies. All customization options are easy to install and upgrade-safe, which enables merchants to continue getting platform benefits when Shopify releases new products such as Shop Pay, or features such as One-page checkout.
For a detailed breakdown of the available technologies for customizing checkout, and ways that you can extend checkout, refer to the options for customizing Shopify checkout.
Getting started
Anchor link to section titled "Getting started"Learn how to customize and extend checkout by following one of our use case tutorials.
Checkout UI extensions tutorials
Anchor link to section titled "Checkout UI extensions tutorials"Shopify Functions tutorials
Anchor link to section titled "Shopify Functions tutorials"A report identifying your current checkout customizations is available in the Shopify admin. The report provides high-level guidance to map customizations to Checkout Extensibility. Use this report to simplify your review of your existing customizations and to help you upgrade to Checkout Extensibility faster. Learn more.
To upgrade a checkout.liquid
customization to Checkout Extensibility, take one or more of the following actions:
Use a public app that's built using extensions.
We're adding new checkout apps to the Shopify App Store on a regular basis. If there currently isn't a suitable public app for your customization, then consider simplifying your checkout temporarily and adding new apps to your store as they become available.
Build a custom app using extensions, or hire a service partner to build one for you.
In some cases, after you've upgraded you can revert to checkout.liquid
until its sunset dates.
If you're upgrading a store to Checkout Extensibility, we recommend planning your in-checkout, Thank you page, and Order status page upgrades together, when possible, for the following benefits:
- Avoid maintaining multiple tech stacks, like UI extensions and
checkout.liquid
. - Apply styling once to the entire experience.
- Manage one sunset date for
checkout.liquid
rather than one date for pre-purchase pages and another for Thank you and Order status pages.
If this isn't possible, then we recommend prioritizing the upgrade for in-checkout pages first and upgrading after-purchase pages after that.
Best practices
Anchor link to section titled "Best practices"To optimize your app development experience, Shopify has established a set of best practices that you can refer to when developing an app that extends checkout.
Product roadmap
Anchor link to section titled "Product roadmap"Some checkout customization features are in development and will be released later this year. The following are the features on our roadmap and our estimated launch dates:
UI extensions
Anchor link to section titled "UI extensions"Stores that subscribe to the Shopify Plus plan can add UI extensions to their Checkout, Thank you and Order Status pages. Stores on Basic, Shopify, and Advanced plans can only add UI extensions to their Thank you and Order Status pages. Merchants can install apps from the Shopify App Store or build custom apps that contain UI extensions.
Milestone | Target |
---|---|
Checkout UI extensions available on all eligible Plus stores | January 2023 (shipped) |
General availability of extensions on the Thank you and Order status page (Plus plan only) | November 2023 (shipped) |
General availability of extensions on the Thank you and Order status page (all plans above Starter) | May 2024 (shipped) |
We'll continue adding API capabilities to help you access the right functionality in extensions. We'll also continue adding UI components that offer performant patterns on our design best practices. We release new components and APIs into the unstable API version first, and promote to the next stable release based on Shopify's API version release schedule.
