Shopify App Extensions and Theme App Blocks

App extensions and theme app blocks are the modern, tidy way for Shopify apps to integrate with a store. They replace the fragile code snippets that used to be pasted into themes by hand.

Theme app blocks

Theme app blocks let merchants drop an app's features into their theme from the editor with a click. There's no manual code editing, and the block can be moved or removed safely. Merchants like the simplicity, and it keeps the store safe through theme upgrades.

Other extension points

• Admin extensions surface app features inside the Shopify admin.
• Checkout extensions add functionality to checkout (on Plus).
• Functions power custom discount, shipping and validation logic.

Why it matters

Building on extensions rather than hacks keeps apps fast, secure and compatible with Shopify updates. That's better for merchants and for the long-term health of the app itself.
