Authentication

HelioNote REST API uses API key–based authentication to secure access to all endpoints.

Overview

Authentication ensures that only authorized developers and applications can access the HelioNote API. Every request must include a valid API key.

Authentication Method

Developers receive an API key from the HelioNote Developer Portal. Each request must include the key in the HTTP authorization header.


GET /notes HTTP/1.1
Host: api.helionote.com
Authorization: Bearer YOUR_API_KEY

Security Considerations

  • Keep your API key private. Do not share or hardcode it in public repositories.
  • Rotate API keys regularly to minimize security risks.
  • Always use HTTPS when sending requests to the HelioNote API.
