I’m building a POD Shopify store for 2 products from Printify. The Key Requirements: Metaobjects Architecture: All designs must be stored as Shopify Metaobjects to allow automated uploads in the future. Dynamic Customizer: Integrate Teeinblue (or similar) so it pulls the artwork assets and Design IDs directly from the Metaobjects. Duo-Preview: Real-time live preview of the designs. Markets: Setup subfolders (/de, /uk) with Geo-IP and Hreflang tags.
