Getting Started with PrintOS Site Flow


The PrintOS Site Flow API is a RESTful HTTP-based API that allows you to validate and submit production orders as well as querying and cancelling existing orders.

Getting Started:

  1. Visit the Authentication page.
    • Request a PrintOS account (if needed), provide as much information as possible to the request form.
    • Follow the directions for generating a Key/Secret within PrintOS.
    • Look over the documentation regarding the HMAC authentication headers.
  2. Head to the Documentation page for information about each API endpoint.
  3. Go to the HP Inc. GitHub repository for code samples for the Authentication headers and API calls.


Certain HTTP headers are required to authenticate the API calls. These headers are generated using a current timestamp following the ISO 8601 format and a Key/Secret combination. Without the headers, you will receive an authentication required error. The Key/Secret is generated from within your PrintOS account. For more in-depth information on generating these headers see the Authentication page.
