FastEditor Developer Documentation

Build product-personalization experiences with FastEditor. These developer guides explain how to open the editor from a webshop or client portal, create secure SmartLinks, receive completed designs through sale notifications, and retrieve print-ready output files.

Editor integrators can explore authentication, catalogue discovery, product configurations, add-to-cart behavior, iframe overlays, and file delivery. Each API reference includes request parameters, response fields, authentication requirements, and copyable examples.

White-label platform operators can learn how to connect login and signup flows, manage users and projects, work with shopping carts and order items, import pricing, configure shop integrations, rotate API keys, apply branding, connect custom domains, and receive order-status webhooks.

Product suppliers can learn how to onboard catalogues and describe base SKUs, printable configurations, virtual SKUs, print methods, print positions, product images, masks, fill lines, print-proof data, and interactive 3D models.
