Overview
While Upcart includes a built-in preview feature that lets you view the cart on your live theme without publishing it (found in the top-left corner next to Cart Status), there are cases where you may need to test it directly within the theme editor.
Follow the steps below to do this safely.
Disclaimer:
You will need to briefly enable Upcart on your live theme, but this process takes less than a minute if done correctly.
Steps to Follow
In the Upcart app interface, click the Cart Status dropdown and select Active.
In Shopify, go to Online Store > Themes > Live Theme > Customize.
In the top-left corner, select App Embeds, then enable Upcart Bridge.
Note: Upcart is not live on your store yet.
Repeat the same step for your Draft Theme in the theme library.
Return to the Upcart interface and click Next to proceed to Step 2.
Test compatibility as needed, or set all options to Yes, then click Next.
In Step 3, click Activate Upcart.
Note: Upcart is now temporarily live on your store.
Return to your Live Theme settings (repeat Steps 2 and 3) and disable Upcart Bridge.
✅ Success! Upcart is now active only on your Draft Theme.
Important Note
As outlined in the Quickstart Guide to Upcart, activation requires two parts:
Enabling the app in the Upcart interface.
Enabling it in your theme’s app embeds.
Upcart will not activate in the back end unless it is also enabled in your live theme’s app embeds (as described in Step 1 of the onboarding process).
You will need to temporarily enable Upcart in both your live and draft themes before activation. Once activated, you can safely disable the Upcart Bridge on your live theme.
