Represents shipment tracking information. This object supports two mutually exclusive usage patterns:
Reference Mode: Pass the tracking ID which created via the Tracking API. This enables full tracking capabilities.
Inline Mode: Pass the tracking_number (and optional slug) directly. This is strictly for record-keeping purposes and does not create an active tracking task, and hence AfterShip system would not provide status updates to this tracking number.
The unique identifier of a tracking resource previously created via the Tracking API.
