Shopify's New Checkout Extensibility: Your Questions Answered

Shopify's spirited community is never short of questions, and if you've ever thought over inquiries regarding the new Checkout Extensibility, you're in the right place. In this article, I've collected the top 10 frequently asked questions from Shopify merchants and developers and provided answers to clarify the secrets surrounding its exciting features.

1. Are the new Checkout Extensibility tools available for non Shopify Plus users?

The answer, for the time being, is that only Shopify Plus merchants have access to the full range of features offered by the new Checkout Extensibility. However, non-Shopify Plus users can dip their toes into basic checkout customization and post-purchase page modifications. Moreover, there's an option to test these features in developer mode. I'll show you how to do this later.

2. How to activate Checkout Extensibility for Shopify Plus merchants?

For those fortunate enough to be Shopify Plus merchants, the process of activating Checkout Extensibility is straightforward. To make use of this feature, your store must be on the Shopify Plus plan. However, some features are incompatible with Checkout Extensibility, such as Advanced Cash on Delivery, In Flight API Mutations or Unsupported Hosted Payment SDK Gateways.

Shopify questions

2.1. What if you're not a Shopify Plus merchant, but eager to test the features?

If you're not on the Shopify Plus plan but are eager to experiment with Checkout Extensibility, here's the solution: create a new development store in your partner's account.

When setting up a new development store in your Shopify partner's account, you might need an affiliate panel or expert support. At Hatimeria, our experienced team is ready to assist. Contact us for expert assistance.

During this process, select Developer Preview and Checkout Extensibility, and consider starting with sample data. It's highly recommended. Following this, you'll see a note in the bottom left corner confirming that your Checkout Extensibility is now active.

3. Do I need a Shopify Partner account to activate Checkout Extensibility?

5. Extending your checkout with custom designed React components

shopify questions and answer

Is it possible to add custom components to your checkout? In short, no, you're not allowed to include custom components. However, you can extend your checkout with preset components available in the Checkout UI Extensions library. This library is extensive and versatile, catering to various business needs. And the great news is that Shopify is still working on extending it.

6. Adding custom CSS with the new approach

shopify questions and answers

With this evolving approach, adding custom CSS directly to your checkout is no longer allowed. You can make basic visual changes through the Settings panel, adjusting elements like logo position, background color or fonts. For more extensive customization, it's recommended to consult with a developer to explore styling possibilities using the new Branding API.

7. Adding Custom HTML Elements

shopify questions and answers

Adding custom HTML elements is similarly restricted. Just like custom CSS, it's not allowed. However, the Checkout UI Extensions components library provides a wealth of options to execute most ideas using preset components. For specific cases, we recommend reaching out to a developer to discuss your options.

8. Modifying default checkout elements

shopify questions and answers

Changing or customizing default elements in your checkout can usually be achieved through a straightforward setup in the admin panel. Combine this with the Branding API and components from the Checkout UI Extensions library for versatility. Generally, you cannot remove, hide or modify default elements directly.

9. Compatibility of Checkout.liquid and Checkout Extensibility

Checkout Extensibility is not compatible with Checkout.liquid. It serves as a replacement for Checkout.liquid customizations, introducing new and upcoming features.
