# Overview

> Interact with the Lantern Storefront REST API

# Storefront REST API

The Lantern REST API allows you to build custom storefront experiences or integrate with other services.

All API endpoints are accessed through Shopify's App Proxy. The base path for all endpoints is `/a/lantern`.

## Authentication

All requests to the REST API will be authenticated using the standard Shopify App Proxy signature validation. Shopify performs this validation on your behalf when the request is made from your storefront domain.

Requests without a valid signature will result in a `401 Unauthorized` error.
