Build a custom Shopify Post-Purchase Extension and Thank You Page cross-sell component using Node.js, React, and Shopify CLI @shopify/checkout-ui-extensions-react. 1. DATA MODEL: Read product recommendations directly from target product metafields ('custom.post_purchase_upsell_id' and 'custom.upsell_discount_percent'). Store analytics events (impressions, accepts, rejects) in a simple SQLite database. 2. CORE FUNCTIONALITY: Implement a Post-Purchase Extension hook that triggers post-payment before the Thank You page. Evaluate purchased line items against product metafields. If an upsell product is defined and in stock, fetch variant details via GraphQL Admin API. Render a clean UI showing product image, variant selector, discounted price, and 'Add to Order with 1-Click' button. Upon user click, call Shopify's post-purchase calculate and accept-offer APIs to add the item to the order without re-entering payment info. If rejected, proceed to Thank You page. 3. THANK YOU PAGE EXTENSIONS: Create a Checkout UI extension targeted at 'purchase.thank-you.block.render' displaying a secondary cross-sell grid and a customer birthdate collection input saved to order metafields. 4. FAILURE MODES: If payment token capture fails or API times out (>2000ms), silently bypass post-purchase offer and route customer directly to final Thank You page without disrupting original purchase. Out of scope: Visual drag-and-drop page builder, multi-step branching funnels, third-party tracking app sync.
