Unicorn’s Preview feature lets you test a draft cart on your theme without customers seeing it. You can check your offers, free gifts and free shipping all work before you go live.
🧠 Pro Tip: Preview scopes your offers to the cart you’re testing. Discounts and free gifts only apply in the Unicorn cart preview and not on your live site, so you can test freely.
🛠️ How to Set It Up
Option 1: Preview a draft cart on your live theme
This works once you’ve completed the onboarding steps to install Unicorn on your theme.
Go to Dashboard > Cart and open your draft cart. [Confirm path]
Click Preview at the top of the cart.
Your store opens in Preview mode. You’ll see a purple Preview bar at the top of the page. If you don’t see it, you’re not in Preview mode for that cart.
Add items to your cart to activate your offers. Check that free gifts are adding and free shipping discounts are applying as you expect.
When you’re happy, go back to your cart and change the Status to Live. The cart is now active on your store.
Option 2: Preview a cart on a draft (preview) theme
Preview works differently here, because a draft theme isn’t your live theme.
Follow onboarding steps one and two and edit the theme, so the app block and script tag are activated on your draft theme instead of your live theme.
Set your cart Status to Live. This is needed to preview a cart on a draft theme.
Go to Online Store > Themes and open the preview for your draft theme.
Your draft theme opens with your live cart inside it, so you can test it there.
When you’re happy, publish the theme. The cart is already live, so the theme and cart go live together.
