Type of tracking event.

values
DELAYEDINFOPICKED_UPPINGCOVEREDDISPATCHED
eventUtc
required
- Type: Format: date-time
  
  Event time as a UTC ISO 8601 timestamp with an offset (e.g. ending in Z, as in 2026-09-11T23:00:25Z). When isLocalTime is true, send a naive local timestamp with no offset instead (e.g. 2026-09-11T18:00:25).
city
Type: string

City closest to the event location.
country
Type: string

Country of the event location, as an ISO 3166-1 alpha-2 code. Used to disambiguate the postalCode lookup when isLocalTime is true; defaults to US when omitted. Only US, CA, and MX are currently supported for this lookup — any other value falls back to US.
dispatcher
Type:

Contact information for a person associated with a tracking event.

Properties: 5
driver
Type:

Contact information for a person associated with a tracking event.

Properties: 5
isLocalTime
Type: boolean

When true, eventUtc and nextEtaUtc (if present) are treated as naive local times and converted to UTC using the timezone resolved from latitude/longitude, postalCode, or city/stateOrProvince (in that priority order); country (defaults to US) helps disambiguate the postalCode lookup. One of latitude/longitude, postalCode, or city/stateOrProvince must be present when isLocalTime is true.
latitude
Type: number
longitude
Type: number
nextEtaUtc
- Type: Format: date-time
  
  Next estimated arrival time as a UTC ISO 8601 timestamp with an offset (e.g. ending in Z, as in 2026-09-12T08:01:05Z). When isLocalTime is true, send a naive local timestamp with no offset instead (e.g. 2026-09-12T03:01:05).
nextSequence
Type: integer

Sequence number of the stop nextEtaUtc applies to, matching LoadRouteStop.sequence.
notes
Type: string

Free-text context from the carrier communication.
postalCode
Type: string
stateOrProvince
Type: string

State or province closest to the event location.
temperatureF
Type: number

Temperature in Fahrenheit, if reported by the source.
