Use this guide to get FoxSell Bundles Plus installed, create a first bundle, and locate the metafields and metaobjects that power partner-built storefront experiences.

​
Install the app

1

Install FoxSell Bundles Plus

Install FoxSell Bundles Plus from the Shopify App Store, approve the requested permissions, and open the app from the Shopify admin.
2

Create a bundle

Use the app to create the bundle type your storefront needs. For custom PDPs, Mix and Match, Volume, and Cross Sell bundles expose the most commonly used storefront data through Shopify metafields and metaobjects.
3

Publish and verify the bundle product

Save the bundle, make sure the generated bundle product is available to the sales channel you are building for, and confirm the selected products and variants are published.
4

Read the bundle data

In your theme or headless storefront, read the bundle product metafields from the FoxSell app namespace and use the matching data structure page for the bundle type.

​
Choose the right reference

Fixed Bundles

Predefined products sold together as one offer.

Mix and Match Bundles

Customer-selected products, quantity options, add-ons, and template metafields.

Volume Bundles

Quantity-based tiers and discount configuration.

Cross Sell Bundles

Related products shown alongside a main product.

​
Storefront setup checklist

  • Install the app on the merchant store and create the bundle in FoxSell.
  • Confirm the generated bundle product is published to the storefront channel.
  • Read bundle configuration from the bundle product metafields, not from hardcoded storefront data.
  • Use the data structure page for the bundle type to map metafield values to your UI.
  • When adding Mix and Match bundles to cart, send the FoxSell line item properties documented in the Storefront API examples.

​
App namespace

FoxSell stores partner-facing bundle data in the app-owned namespace used throughout these docs: 
{% liquid
  assign app_namespace = 'app--67872686081'
%}
For example, Mix and Match bundle data is available from the dynamic_add_ons_bundle metafield on the generated bundle product. 
{% liquid
  assign dynamic_add_ons_bundle_config = product.metafields[app_namespace].dynamic_add_ons_bundle.value
%}
Start with the bundle-specific data structure page before building a custom UI. Those pages include the metafield keys, nested field shapes, and cart properties expected by FoxSell.
