Overview

The Cardinal API uses an API key passed via the x-api-key header for all requests.
Every request must include your API key or it will be rejected.

​
Obtaining an API Key

  1. Log into the Cardinal Home Page
  2. Create a new API key or copy an existing one
Important: Keep your API keys secure. Do not share them publicly, and rotate them regularly. If a key is compromised, revoke it immediately from the dashboard.
