Retrieves tracking data for any package shipped with Delivery or Signature confirmation.
Syntax
nsoftware.InShip.Uspstrack
Remarks
This component is used to check the delivery status of any package without having to go to the USPS web site to make any queries about the status of your shipment. This component can retrieve tracking information for any Express Mail package, any package sent to a US address utilizing the Delivery or Signature confirmation option, as well as all International shipments.
To retrieve tracking information, simply provide your tracking number as a parameter into the TrackShipment method. The RequestType property determines which of the two types of requests are sent. They are listed below.
| Detail | Returns a detailed account of the package status at every step along the way. |
| Summary | Returns an overview of the current package's status in the Status field. |
For the Detail request type, information will be provided for each time the barcode on the label was scanned. There may be many such tracking events as a package travels to its destination, and information on each hop is contained in the TrackEvents property. Information is returned in the following fields:
| Date | The date this tracking event occurred. |
| Time | The time at which this tracking event occurred. |
| City | The city where the tracking event occurred. |
| State | The state (or province) where the tracking event occurred. |
| ZipCode | The zip code where the tracking event occurred. |
| CountryCode | The country where the tracking event occurred. |
| Status | Description of the tracking event (enroute, delivered, etc) |
| Company | Name of the firm the package was delivered to. |
| PackageSignedBy | Name of the person who signed for the package. |
The following example will return sample data from a special USPS test server:
USPSTrack.USPSAccount.UserId = "YOURIDHERE"
USPSTrack.USPSAccount.Server = "http://testing.shippingapis.com/ShippingAPITest.dll"
USPSTrack.TrackShipment("EJ958083578US") ' Only works with above URL
