Need UPS session cookies inside PHP script (willing to $pay$ for solution)

Im trying to write a Script to automate printing of UPS shipping labels from my shopping cart (zen-cart).
I am using Curl to Post the information to UPS shipping page. Problem is, in order to post, i need to have the UPS session cookies:
session_ups_com and com.ups.com_ups_uis.sData

I can retrieve them manually by using "Live HTTP Headers" software. But I cant figure out a way to get them in the script.
If i copy and paste these cookies in the script - it works well.

<?php

//this part does the posting

$url = "https://www.ups.com/uis/create?loc=en_US&WT.svl=PNRO_L1";
$post = "Country=&Company=&.."; //this string needs to be created. for the sake of this test, i used "Live HTTP Headers" plugin for Firefox to track a post string (i did not include it here for security reasons).

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

//if i login to ups.com and paste the session cookies into this line, the script works. but it kind of makes it pointless. does anyone know a way to extract these cookies in some way?
curl_setopt($ch, CURLOPT_COOKIE, "{current session cookies");


curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

$result = curl_exec($ch);

curl_close($ch);

header("Location: https://www.ups.com/uis/create?ActionOriginPair=RESUME___CreateAShipment&loc=en_US");

?>

PHP:

 

Have you looked at the UPS shipping API? It will generate shipping labels for you to print.

 

yes, i applied on the UPS website to get access to their API, but have not heard back from them. I read somewhere on ups.com that they only give access to accounts who ship over 50 packages per day (or week). Any ideas?

 

I guess i have to figure out a way to login to UPS with CURL. Something like this for Amazon:

but it just doesnt seem to work for UPS.
