Start a charging session

When a session starts we want to receive a StartTransaction event.

Associated cards

Charging cards offered at the charger can be viewed in the Stekker app. Users can assign them to a charging profile for automatic smart charging. Every time a charging session is started with the same card, the same parameters will be used to create a charging schedule (or: planning), such as the desired departure time and associated charging percentages.

For the Stekker API, it is sufficient to send an authentication_identifier of a charging card with the "session start" event. After a session is detected by Stekker, a push notification is sent to the app so you know which conditions are being used for smart charging.
