Build your cart in Sternify, then enable its theme connection. The drawer needs both saved app settings and the Sternify app embed. Requires Pro.
1. Design and enable the drawer
Open Cart Drawer. Choose a design if offered and customize the header, body, and footer.
Keep the product list, subtotal, and checkout action clear. Add optional upsells, rewards, notes, or discount entry.
Check the empty-cart preview, enable the drawer, and save.
Enable the cart and save your settings. The preview uses demonstration content.
2. Connect the theme
Open the theme customers use in Shopify’s theme editor.
Enable the Sternify app embed and save the theme.
Open the storefront and add a product.
For the exact theme steps, use Enable the Sternify app embed. If the drawer opens for some shoppers but not others, open Cart Drawer → General → Customer visibility and check Disable drawer for customer tags. A matching tag can intentionally show the native cart; compare the same product while logged out and as the affected customer.
Check the result
Add, remove, change quantity
Items and subtotal update correctly.
Reach a reward threshold
The configured discount or gift applies, not only its progress-bar label.
Mobile and empty cart
Content remains readable and checkout is accessible.
For progress rewards, configure the actual discount or gift, including whether a gift is automatic or customer-selected. Test the countries and currencies you serve.
If it does not open—or two carts open
Check enabled + saved in Sternify and the embed in the same theme. Customer-tag exclusions can intentionally show the native cart for certain logged-in shoppers, even when the editor shows Sternify. If two drawers open, disable the unintended drawer through its normal settings.
To stop the Sternify drawer, disable it and save. If you see an express-checkout integration warning while saving, send the warning to support.
