How to Configure Automated 100% Off Gifts with Purchase Using Shopify Functions

A step-by-step tutorial on setting up automated free gift discounts at checkout with zero liquid theme code and sub-5ms WebAssembly calculation speed.

The problem with manual free gift coupon codes

Expecting shoppers to manually find and paste a promo code to receive a free gift leads to friction, cart abandonment, and customer support tickets when codes fail to combine with existing store offers.

Configuring GiftLift in three simple steps

  1. Define spend tiers in GiftLift:
    • Tier 1: Spend $50 → 100% discount on Sample Product A.
    • Tier 2: Spend $100 → 100% discount on Premium Gift B.
  2. Add Theme App Block to your Cart: Open Shopify Theme Customizer, select your Cart Drawer or Cart Page, add the GiftLift Progress Bar block, and customize colors to match your brand palette.
  3. Save and Publish: The rule compiles to Shopify Functions Wasm and executes natively during checkout in under 5ms.

Full compliance with Shopify GDPR webhooks

GiftLift includes verified endpoints for customer data request, data redaction, and store uninstallation handlers. No personal customer data is stored on external servers.
