Answer 1

When I made my first paypal script one of the most useful things that I did was to log every piece of information that came through. I just dumped everything into a text file whenever Paypal called the confirmation page. It was incredibly helpfull to see what they were passing over and to debug. Paypal sends a POST of the transaction.

$dumpfile = "=== post fields\n";
foreach($_POST as $k=>$v)
    $dumpfile .= "[$k] => $v\n";

$dumpfile .= "=== http request headers\n";
foreach(apache_request_headers() as $k=>$v)
    $dumpfile .= "[$k] => $v\n";

file_put_contents('pathToAWritableFile', $dumpfile);

I hope this saves you some headache. As a side note, I still keep all the paypal request info in a database in case the purchase logic fails after I update the paypal confirmation script, that has saved me a couple of times.

Here's a tut on how to handle the callback from paypal.

https://developer.paypal.com/ is a great place to start.

They offer guides and code libraries and examples there.
