As of August 13, 2024, Checkout Extensibility became the only available checkout option. This means that any customizations made in checkout.liquid, including app integrations, will become obsolete.
If you didn't prepare in time, your checkout could have affected the shopping experience, conversion, and sales.

What is Checkout Extensibility?
Checkout Extensibility is the evolution of checkout on Shopify Plus, designed to offer a more secure, scalable, and flexible customization.
Unlike the old checkout.liquid, which required direct code editing, this solution adopts an application-based architecture with a modular approach that enhances speed, security, and user experience.
Benefits of Checkout Extensibility
Migration is not only mandatory, but it also offers key advantages for your e-commerce:
-
Faster and higher conversion
Payment interactions up to 2 times faster and an average increase of +1% in conversions. -
Automatic updates
Immediate access to new features without the need to maintain manual code. -
Greater security
Everything runs in sandbox environments, protecting the shopping experience. -
Comprehensive shopping experience
Customize not only the checkout but also thank you pages, order status, and customer account.
Key Features of Checkout Extensibility
With this update, you will be able to:
- Use a drag-and-drop visual editor to customize colors, logos, fonts, and backgrounds.
- Add checkout apps with custom logic and post-purchase functions without touching code.
- Manage events and pixels from a single place.
- Integrate brand APIs to customize your checkout to match your store's style.
- Set up custom payment and delivery methods with Shopify Functions.
- Build custom applications with UI extensions and post-purchase.
Implementation challenges in LATAM
In Latin America, the biggest challenge is in address management.
Each country has its particularities:
- Chile → regions and communes.
- Colombia and Peru → departments, provinces, and districts.
- Argentina and Brazil → additional information such as floor or apartment number.
This requires specific adaptations to comply with local regulations and enhance the customer experience.
At Acid Labs, we help your business set up Checkout Extensibility with custom fields, data validation, and optimization for LATAM.
