Field level Description

Field	Type	Optional/Required	Description
eventSubscriptionId	String (UUID)	Required	A unique identifier representing the subscription through which this event was delivered. It ensures traceability between the event and the organization's registered RMS subscription.
eventType	String	Required	Specifies the nature of the event being reported. For this payload, status.trailer indicates that the event provides operational status details related to the trailer.
eventVersion	Number	Required	eventVersion indicates the schema version of the event, allowing producers and consumers to interpret the event consistently as the schema evolves.
eventId	String (UUID)	Required	A globally unique identifier assigned to this specific event instance. Useful for event deduplication, tracking, and audit logging.
assetId	String (UUID)	Required	Identifies the physical asset (e.g., vehicle, trailer, equipment) associated with this event. Used to correlate telemetry with a specific asset in fleet management systems.
unitId	String	Required	A unique identifier of the telematics device generating the event. It often includes a namespace (e.g., traxee:) followed by the device's serial or IMEI-like identifier.
registeredOn	DateTime (ISO 8601 timestamp, UTC)	Required	The timestamp representing when the event was detected and recorded by the device.
eventData	Object	Required	The eventData section contains all trailer-specific operational metrics recorded at the time of the event.
axleLoad	Number (kilograms)	Optional	Represents the measured load applied across the trailer's axles at the moment the event was generated. This value helps monitor vehicle loading conditions for safety, compliance, and performance optimization.
mileage	Number (kilometers)	Optional	Indicates the total cumulative distance traveled by the trailer up to the event timestamp. Mileage values support maintenance scheduling, lifecycle tracking, and operational reporting.
speed	Number (km/h)	Optional	Shows the instantaneous speed of the trailer at the time of measurement. This metric assists in understanding movement patterns and verifying operational conditions during transport.
