Journey Events API 1.0.0 documentation

AsyncAPI documentation for the Journey Events stream. The Journey Events stream publishes lifecycle events for vehicle trips in near real time. A journey emits events as it starts, updates while in progress, and ends when completed. What this stream provides

Journey lifecycle state (start, update, end)
Vehicle, customer, and driver identifiers for correlation
Start/end location and address context
Distance, duration, speed, and fuel/energy metrics
Driver behaviour counters and operational indicators
Place and input enrichments (spl, epl, ins)

Typical usage

Monitor journey progress in operational dashboards
Trigger downstream workflows on start/update/end transitions
Build analytics for utilisation, efficiency, and safety

Operation ID: receiveJourneyEvent

Channel for journey events (start, update, end) Receives journey events when a journey starts, updates, or ends. The ‘state’ field indicates the journey lifecycle stage:

‘start’: Journey has started
‘update’: Journey data has been updated
‘end’: Journey has completed

Message Journey Event `JourneyEvent`
