Shopify Integration

The @domos/shopify package integrates DomOS directly with Shopify themes. It features native cart synchronization, product catalogs querying via the Storefront API, and checkout redirection.

1. Installation

CDN Script Injection (Theme assets)

1. Upload the bundled domos-shopify.min.js file into your theme's assets/ directory.
2. Edit your layout file layout/theme.liquid and paste the script setup right before the closing </body> tag:

<script src="{{ 'domos-shopify.min.js' | asset_url }}" defer></script>
<script>
  document.addEventListener('DOMContentLoaded', function () {
    DomOSShopify.init({
      apiKey: '{{ shop.metafields.domos.api_key }}',
      storefrontToken: '{{ shop.metafields.domos.storefront_token }}',
      shopDomain: '{{ shop.permanent_domain }}',
      widget: {
        agentName: 'Léa',
        agentTitle: 'Shop Assistant'
      }
    });
  });
</script>

App Embed Block (Theme Editor — Shopify 2.0)

If you prefer not editing theme liquid files directly:

1. Save embed/blocks/domos-widget.liquid into your theme's blocks/ directory.
2. Open your Shopify Theme Customizer > App Embeds and enable DomOS Chat Widget.
3. Fill in your API Credentials directly within the sidebar inputs.

2. Configuration Settings

Initialize settings with storefront access tokens to unlock database catalog searches:

import { DomOSShopify } from '@domos/shopify';

DomOSShopify.init({
  apiKey: 'dk_live_xxxx',
  
  // Credentials required for search_products, get_product
  storefrontToken: 'shpat_xxxxxx',
  shopDomain: 'mystore.myshopify.com',
  storefrontApiVersion: '2026-01',
  
  features: {
    orderTracking: true,
    productRecommendations: true
  }
});

3. Pre-configured Shop Tools

Once initialized, the Shopify SDK automatically registers three groups of tools:

Shopping Cart Tools

• add_to_cart (risk: 'low'): Adds variants to the active cart using Ajax APIs.
• update_cart (risk: 'low'): Updates variant quantities.
• remove_from_cart (risk: 'low'): Removes an item.
• get_cart (risk: 'none'): Queries the active cart items and calculations.

Catalog Exploration Tools

• search_products (risk: 'none'): Queries variants by collection, price range, type, or tags.
• get_product (risk: 'none'): Returns details, images, description, and available variant options.
• select_variant (risk: 'none'): Selects or focuses variants in the DOM on active detail pages.
• navigate_to_product (risk: 'none'): Redirects viewport.

Checkout & Accounts

• initiate_checkout (risk: 'high'): Shows a HITL security confirmation, then redirects the customer to /checkout.
• apply_discount (risk: 'none'): Appends a coupon query string before checkout redirection.
• get_order_status (risk: 'none'): Returns recent customer purchase status.

4. Enabling Customer Order Tracking

To allow the get_order_status tool to fetch real order logs, inject the customer access token inside theme.liquid:

{% if customer %}
  <script>
    window.__domos_customer_token = {{ customer.access_token | json }};
  </script>
{% endif %}

5. Variant Selection Theme Compatibility

Theme DOM architectures vary across Shopify. The select_variant tool matches multiple layouts:

Layout Pattern	Targeted Themes	Description
Select Dropdowns	Debut, older liquid templates	Finds select[name="id"] element and updates value.
Radio Option buttons	Dawn, Prestige, Impulse	Scans option labels matching variants and dispatches click events.
Custom Dispatch	Hydrogen, headless storefronts	Dispatches custom Javascript event: variant:selected.

For headless templates, hook into the event dispatcher to update selection states:

document.addEventListener('variant:selected', (e) => {
  const { variantId, options } = e.detail;
  // Update state
});
