Yes, PrintNow has an Online Editor API for 3rd party integration into any Storefront. We also have Magento, WordPress (Woo-Commerce) and Shopify plug-ins we developed ourself using that Online Edtior API. Most integrations add a “Customize Now” button on the product detail pages to load the HTML5 Editor. The API provides methods to link products and user accounts, provides a way to save projects and thumbnails generated by PrintNow as well as optional PDF proof downloads. Once a order is placed within 3rd party shopping cart the order is merged and you will receive the print-ready PDFs for production.
