# Headless Shopify

LoyaltyLion has support for headless Shopify stores. Install LoyaltyLion via Shopify as normal, and follow the steps below to handle the frontend implementation of the SDK on your side.

In order for LoyaltyLion UI to show on the page, you need to:

1. [Install the SDK](/sdk/installation)
2. [Initialize the SDK](/sdk/initialize-sdk/)
   <Warning>
     The SDK should be loaded on every page on your store, otherwise your
     customers might not be able to view the loyalty program.
   </Warning>
3. [Handle customer authentication](/sdk/customer-authentication/)
