Cachet is built on the belief that your service status is open and transparent, therefore all GET requests are public and require no authentication to access the information.
Authenticated requests (those that POST, PUT or DELETE) require an API Token.

​
API Token

API Tokens are the preferred method of authentication. Once you have your token you’ll need to add a new request header of Authorization: Bearer $TOKEN: 
curl -H "Content-Type: application/json;" -H "Authorization: Bear YOUR_KEY_HERE" -d '{"name":"API","description":"An example description","status":1}' https://v3.cachethq.io/api/components
