  title: Monta Public Authentication Charges API
  description: 'The Monta Public API lets developers connect to the Monta EV-charging platform to read charge points, start and stop charges (charging sessions), inspect EVSE availability and pricing, and read wallet transactions. Authentication uses OAuth2 client-credentials: exchange a clientId and clientSecret for a short-lived bearer access token (and a longer-lived refresh token) and send it as a Bearer token on each request.'
