CLONE — YOU CAN REBUILD THE FEATURE
You pay Zipify for pre-built conversion-optimized templates, split-testing machinery, and zero-code Shopify Admin setup. The underlying technical function relies entirely on Shopify's native Checkout Post-Purchase Extension APIs, which allow apps to inject an intermediate step before the thank-you page. Building a custom post-purchase offer using Shopify's UI components and Remix framework is straightforward with AI assistance. You lose out-of-the-box A/B testing statistical modeling and pre-designed visual UI editors, but eliminate scaling SaaS tax on high-volume stores.

Why this verdict
Zipify OCU leverages Shopify's native Post-Purchase Extension and GraphQL Order Editing APIs to add items to an existing transaction. A custom Shopify App using Cursor can implement identical offer logic without paying percentage-based or tiered monthly fees.

The one-shot build prompt
Paste it into your agent of choice. Nothing else needed.
Build a custom Shopify Post-Purchase Upsell app using the Shopify Remix App Template and Checkout UI Extensions.
1. DATA MODEL & BACKEND (Prisma / PostgreSQL)
- Store `UpsellRule` with fields: `id`, `triggerVariantIds` (array), `offerVariantId` (string), `discountPercentage` (number), `title` (string), `description` (string), `priority` (integer), `active` (boolean).
- Store `AnalyticsEvent` with fields: `id`, `orderId`, `offerVariantId`, `status` ('OFFERED', 'ACCEPTED', 'DECLINED'), `upsellRevenue` (decimal), `createdAt`.
2. EXTENSION FRONTEND (Shopify Post-Purchase UI Extension)
- Create a Checkout Post-Purchase Extension using `@shopify/post-purchase-ui-extensions-react`.
- Upon load, call backend endpoint `/api/offer` passing `initialPurchase` token and order details.
- If a matching rule exists based on `triggerVariantIds`, display product image, title, custom discount message, 'Add to Order' button, and 'Decline' button.
- Ensure render executes under 2 seconds.
3. PAYMENT & ORDER MUTATION LOGIC
- When 'Add to Order' is clicked, send request to `/api/accept-offer` with payment token and initial order ID.
- Backend calls Shopify Admin GraphQL API using `orderEditBegin`, adds the `offerVariantId` line item with applied discount using `orderEditAddVariant`, and commits changes using `orderEditCommit`.
- Handle payment token processing using Shopify's native post-purchase payment call (`calculateChanges` and `submitChanges`).
- Record 'ACCEPTED' analytics event and store upsell revenue generated.
- If accepted or declined, redirect customer to standard Thank You page.
4. FAILURE MODES & EDGE CASES
- If payment fails, render an explicit error message and allow retry or skip to thank-you page.
- If item is out of stock at time of upsell submit, fail gracefully and pass through to thank-you page.
- Respect customer currency and localized pricing.
5. OUT OF SCOPE
- No drag-and-drop visual page builder.
- No dynamic multi-arm bandit A/B testing.
- No pre-purchase or cart drawer widgets.$ each button prefixes agent-specific run instructions · build your own product, never copy proprietary code, trademarks or designs
