Can I use another cart app with the cart drawer?

Two cart drawers clash. Turn off the other app's embed. Upsell and review apps can stay.

Updated November 13, 2026

Two cart drawers clash, so run one at a time. To use ours, turn off the other app's embed in your theme. To keep your other cart, such as UpCart, leave ours off. We close another cart that opens next to ours, but the clean fix is to keep one.

Turn off the other cart

  1. In Shopify admin, open Online Store → Themes.
  2. Click Customize on your live theme.
  3. Open App embeds.
  4. Turn off the other app's cart embed.
  5. Click Save.
  6. Add a product in a private window. One cart opens.

Keeping UpCart as your cart

You can keep UpCart, or another cart app, and use the rest of Section Store next to it. To use our drawer instead, turn off UpCart's embed under App embeds and click Save.

  1. Keep our cart off. On the Cart Drawer page, your cart's status should read Draft. A cart that's on can still give rewards at checkout, even with its embed off.
  2. Keep the Cart drawer app embed off in your theme.
  3. If you use the Upsell block, set its Cart app setting to Upcart Cart Drawer. UpCart then opens after Add. AMP Drawer and Kaching Cart work the same way. With any other cart app, turn on Open cart page.

Bundles work next to your cart app. The widget sits on the product page and leaves your cart app's own add-to-cart requests alone. Shopify applies the discount at checkout.

You do give up what lives inside our drawer, like the reward bar, cart upsells and order addons. They show only in our drawer.

The one-click Turn on cart drawer button stops while UpCart is on. That's expected. Skip it.

How we handle a clash

  • With both Open drawer… settings on, the drawer closes any other cart-like layer that opens around an add.
  • The one-click Turn on cart drawer button, on the store audit and after an AI Pages build, stops if it sees another app's cart drawer. It asks you to turn that app off first. Click I turned it off when you have.

Other apps

  • Apps that add to the cart through Shopify's standard cart address work. The drawer refreshes and opens.
  • Apps that add in other ways may update the cart without opening the drawer. A developer can call SectionStoreCart.open().
  • An app that blocks checkout through onBeforeCheckout hides the express checkout buttons.
