Checkout Extensions Overview
Enhance your Shopify checkout with native extensions that boost conversion and trust
Last updated: 2025-01-16
Checkout Extensions are native Shopify checkout customizations that appear seamlessly within the checkout flow. Unlike third-party widgets or scripts, these extensions use Shopify's Checkout UI Extensions API to render directly in the checkout, ensuring fast performance and a native look and feel.
Shopify Plus Required
Full checkout extensions require Shopify Plus or Checkout Extensibility access. Some features may be limited on standard Shopify plans. Check requirements →
