The Button API is designed around REST. Request parameters must be given as JSON-encoded request body.

The only unusual request parameter is api_key which is sent as a basic authentication username. You can generate and manage API keys in your Button dashboard. API keys are secret and should be treated like passwords by storing them somewhere secure.
