*** THIS IS ALPHA SOFTWARE ***

This module implements the Track & Confirm web service from the US Postal Service. It is a subclass of Business::US::USPS::WebTools.

track( KEY, VALUE, ... )

The "track" method takes the following keys, which come directly from the USPS web service interface:

        TrackID   The tracking number
    

It returns an anonymous hash with the data from the response. Although the USPS API allows one to make multiple queries in a single request, this method one queries one.

If you want to see if something went wrong, check:

        $tracker->is_error;
    

See the "is_error" documentation in Business::US::USPS::WebTools for more details on error information.

tracking_number_regex

Returns the regex that checks a tracking number. I have it in its own method so you can easily override it if I got it wrong.

The USPS shows the valid forms at

is_valid_tracking_number( ID )

Returns a normalized version of the tracking number if ID looks like a tracking number, based on the regex from "tracking_number_regex". Returns false otherwise.

Normalizing ID merely removes all whitespace. Sometimes the USPS shows the numbers with whitespace.

service_type( ID )

Returns the service type, based on the examples shown by the USPS and shown in "tracking_number_regex". I know this is wrong because I have tracking numbers that don't have the same leading characters for Priority Mail International.
