  title: Scalable Press Billing Product API
  description: The Scalable Press API is a REST interface to a print-on-demand and fulfillment platform for custom apparel, accessories, and promotional products. It lets developers browse a wholesale blank-and-printed product catalog, generate price quotes (product, printing, and shipping costs), place and manage print-and-ship orders, track fulfillment through order and item events, create designs and product mockups, and retrieve billing invoices. Authentication uses HTTP Basic auth - your private API key is supplied as the password (the username is left blank). The API spans two versioned surfaces - v2 for product, quote, order, design, customization, and billing, and v3 for event and mockup - both served from https://api.scalablepress.com.
