GetTrackingNumber Method

Generates a Delivery Confirmation Number or a Signature Confirmation Number that can be applied to user-generated labels..

Syntax

uspsship.getTrackingNumber([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

Unlike GetPackageLabel, this method does not actually return a label, but rather returns only a TrackingNumber. This is useful if you have your own Postnet barcode generating software.

Since only the TrackingNumber itself is requested, this method requires a much smaller subset of properties. Any property not listed below will be ignored for this method call.

Required Properties:

Optional Properties:

This method will return the TrackingNumber if it is successful.
