Reservations

Reserve a charging port for a specific user (identified by an RFID tag or other token) so that the connector is blocked for all other users until the reservation expires or is cancelled.

Reservations use the OCPP ReserveNow and CancelReservation messages under the hood. Both OCPP 1.6 and OCPP 2.0.1 chargers are supported. The charger must support the Reservation profile; if it doesn't, the request will be rejected.

POST /api/ocpp/reservations

Reserves a charging port. The reservation is active immediately and expires at expiryDate. Only the user with the matching idTag (or parentIdTag group) can start a session on the reserved connector.

Request body

{
  portId: number;        // Flipturn charging port ID
  expiryDate: string;    // ISO 8601 datetime when the reservation expires
  idTag: string;         // Identifier of the user (RFID UID, token, etc). Max 20 characters.
  reservationId: number; // Unique integer identifier for this reservation (caller-assigned)
  parentIdTag?: string;  // Optional parent identifier for group reservations (OCPP 1.6 only)
  idTokenType?: string;  // Optional. OCPP 2.0.1 only. See below for valid values. Defaults to 'Central'.
}

idTokenType values (OCPP 2.0.1 only):
