Tessen API

NOTE: Requests to the Tessen API require you to authenticate with a Sensu access token or API key. The code examples in this document use the environment variable $SENSU_API_KEY to represent a valid API key in API requests.

The Tessen API provides HTTP access to manage Tessen configuration. Access to the Tessen API is restricted to the default admin user.
