Hidden field / header in redirect?

The redirect after successful purchase is working great. I am getting the key information from PayPal but it's all on the query string (GET). This will allow a user to save the URL and trick my site into producing more product for the user. I would like to set a specific header or set a "POST" variable to validate that the customer indeed came from PayPal. I am using PHP on the other end and I'm able to print out the various arrays and I don't see anything useful. Referrer returns empty. I have set custom fields but none are passed along. 

 

Any ideas are welcome. Thanks in advance.
