This page gets a standard Shopify Liquid storefront live. For Tapcart see Tapcart. For Hydrogen or a custom cart see the Headless Bundles API.

​
Prerequisites

  • A Shopify store
  • Permission to install apps

​
Install

  1. Install Knit Bundles from the Shopify App Store.
  2. Open the app from Apps in Shopify admin. Opening it once provisions the Storefront access token that headless endpoints need.
  3. Create a bundle: add products or collections, set quantity tiers and discounts, then set the bundle to Active and save. See Create a bundle.
Headless endpoints return APP_NOT_INSTALLED until the app has been opened at least once in Shopify admin.

​
Confirm the automatic discount

  1. In Shopify admin go to Discounts.
  2. Find the Knit automatic discount and confirm it is Active.
Without this, the widget can still add items to the cart, but checkout will not apply the bundle price. See How discounts apply.

​
Confirm the product page

  1. Open an online store product that belongs to the active bundle.
  2. The Knit widget should render on the product page (theme app extension).
  3. Add the bundle to cart and start checkout. The bundle discount should appear.
If the widget is missing or the discount is not on the order, see Troubleshooting.
