Data sources

Vizion's API provides milestones that contain a source property indicating the data source of the event

Carrier

When the source property of an event shows "carrier," it means that the information was provided by the ocean carrier. This source is the most common as it directly comes from the carrier's systems.

AIS

AIS, or Automatic Identification System, is a tracking technology used for vessel tracking. If the source property of an event shows "ais," it means that the event was generated based on the vessel's AIS signal.

Ports and terminals

If the source property of an event shows "terminal," it means that the event was generated by the terminal. These will include milestones not commonly reported by steamship lines, such as 'Free time to expire' and 'Available for pickup,' which are sourced directly from terminal operators. This allows you to receive events like 'Discharged from Vessel,' 'Gate Out Full,' and 'Gate in Empty Return' without needing to rely solely on carriers.

Rail

When the source property of an event shows "rail," it means that the event was generated by the rail line. These will include milestones such as 'Container available for pickup,' 'Loaded on rail,' 'Rail arrival,' and 'Rail departure.
