There are two easy ways to test your UFE widget without showing it to the public:
1. Test on an Unpublished Theme by enabling the UFE app extension
You can create a duplicate of your current live theme and test UFE there privately:
- Go to your Shopify admin and create a copy of your live theme (do not publish it).
- In the copied theme, enable the UFE app extension from the App Embeds section as given below. How to enable the UFE app extension?
- Now, preview your funnels directly on the preview version of that unpublished theme.
This method ensures your customers won’t see the widget until you're ready!
2. Test on the Live Theme Without Publishing the Funnel
UFE is designed to make testing super simple — even on your live theme!
You can test an unpublished funnel by simply appending the following to your trigger product URL:
?ufe_preview=true 💡 Example:
https://yourstore.com/products/sample-product?ufe_preview=trueThis works even when the funnel is turned off — as long as it's connected to the product.
Let's see this in action.
As you can see the funnel is not turned on.
Add the ufe add
?ufe_preview=true to your trigger product url and hit enter.
That's it. Keep exploring UFE for more exciting features.
