Google checkout is going to send you a POST to your CGI script. It has to be a name/value pair. One of those name value pairs is going to contain your XML document.

This should dump any data that you receive from a POST request. Use this as your script that Google Checkout will call; it will tell you what name/values you are receiving from them.

#!/usr/bin/perl

use CGI;

my $q = new CGI;

my @names = $q->param();

for my $name (@names) {
  warn "$name => " . $q->param($name) . "\n";
}

Note:This data will be sent to the Apache error_log file.

Your technique worked great! I guess there's a param called POSTDATA that contains what I need. I've written a client and a server that seem to be talking to each other.

Now I need to perform basic HTTP authentication. Any pointers there?

So you need to fetch a URL that uses a username & password? LWP::UserAgent and WWW::Mechanize can both handle this.

That depends, what is the source of the usernames/passwords? Some kind of local database you control, or do you authenticate them through google?

Addendum: for those monks (ie: me) who dont usually care to go looking for proprietary API docs, it would help to include a link to them :)

from the Google documentation:

Google sends you the new-order-notification to inform you that it has started processing an order. The new-order-notification includes the order's shopping cart, shipping method, tax, shipping address, and various other information. Google sends this and all other notifications as raw POST data, not as name/value pairs. You need to reply to the notification with a notification-acknowledgment message via HTTP response. See New Order Notifications for a complete description.

That's what's confusing me. How can I access the raw Post data?
