MasterTrackingNumber Property
Tracking number assigned to the whole MPS shipment.
Syntax
[VB.NET] Public ReadOnlyProperty MasterTrackingNumber As String
[C#] public string MasterTrackingNumber {get;}
Remarks
This is applicable to MPS shipment requests only and identifies the whole shipment.
This value is used as parameter when a cancel shipment request is sent (i.e., when the CancelShipment method is called). It can also be used when tracking a MPS.
MPS shipments are not currently supported in USPS, and thus this property does not return anything for USPS shipments.
For Canada Post, this property will be set to the unique identifier for the shipment.
This property is read-only.
Default Value
""
