  title: Flipturn Access IDs Charging Sessions API
  version: '1.0'
  description: 'The Flipturn API provides read and write access to the Flipturn EV charging management platform: sites, chargers and ports, charging sessions, charger health and uptime, access IDs (RFID cards and vehicles), vehicles, alerts, charger errors, raw OCPP messages, reservations, site power limits, vehicle departure times, and maintenance windows. It is a JSON REST API secured with a bearer API key, designed for integrating Flipturn charging data with ticketing platforms, data warehouses, transportation management systems, and fleet operations tooling. Flipturn also supports OCPI for roaming-partner integration (contact support to enable).'
