These APIs provide information on Charge Stations, Locations and charging events:

  • Location API
  • Session API
  • MeterValues API
  • ChargeStation Notification API

These APIs provide CPOs with information on their locations as well as a 'copy' of any activity that is ongoing on their charge stations.

Except for MeterValues, all other data can be Pushed in real-time to CPOs.

Below is an example when updates to objects take place and abilities to push real-time data.



  • At the start of a charging session, a PUT session request is sent
  • Once an updated MeterValue from the chargestation is received, a PATCH update request is sent
  • Once completed, a final PATCH request is sent.


  • When a new location is created, a PUT request is sent.
  • Upon starting a charging session, the EVSE status is changed from AVAILABLE to CHARGING
    (or unrelated to Charging is could go to a faulted state)
  • Once completed, the EVSE is updated as AVAILABLE again


  • When the CDR is calculated, it is sent as POST

ChargeStation Status Notifications

  • Upon every status update, a PUT update is sent.


  • For completeness, MeterValues are not pushed or available via Webhook. A history of MeterValues can be retrieved via PULL requests.
