Comodo API examples using perl?

I’m trying to generate SSL Certificate expiration reports using perl, but the documentation doesn’t show any practical examples.
For example, I can’t figure out how to create the authData and use it to authenticate. Does anyone have any working examples
of perl code using SOAP::Lite that I can learn from?
This is as far as I’ve gotten:

#! /usr/local/bin/perl

use SOAP::Lite;
use strict;
use warnings;

my $service = SOAP::Lite → service(‘’);
