Your first rule,
from draft to checkout.

1. Open KartVantage in Shopify Admin

Once the app is available to install, use its official Shopify App Store listing and complete Shopify’s installation flow. Open KartVantage from your store’s Apps area.

2. Create a draft rule

Choose a starter template or build a custom rule. Select cart subtotal, total item count, or a selected-product quantity. Set the minimum or maximum and write a clear shopper message.

3. Test a passing and blocking cart

Use the app’s rule test before publishing. Check an amount or quantity below the limit, exactly at the limit, and above it. For product rules, include variants and mixed-product carts.

4. Publish and check synchronization

Publish the rule when the tests match your policy. Check Health & Activity for synchronization information so you can confirm the intended configuration reached Shopify.

5. Add storefront guidance

Open the Storefront area and follow the theme-editor link. Add Cart Progress, Cart Offer, or Cart Summary on a compatible cart template. Preview the presentation before saving your theme.

6. Confirm the full shopping journey

Try valid and invalid carts on desktop and mobile. Continue to checkout to confirm the published rule. Recheck cart drawers and other custom cart surfaces separately.
