Introduction

Documentation for AutoCart — the Shopify app that automatically manages cart items based on configurable rules.

Welcome to AutoCart Docs

AutoCart is a Shopify app that automatically adds, removes, and manages cart items based on configurable business rules. It operates across two main surfaces:

  • Storefront — via a theme app extension that intercepts cart actions and displays gift picker modals
  • Checkout — via checkout UI extensions that evaluate rules at the checkout stage

Extensions Overview

AutoCart is composed of several Shopify app extensions, each serving a specific purpose:
