product key email

where is the users email collected to receive product key?

if it is not collected by paypal?

We're actually writing the the help article on this right now. In the meantime here's the short version. First, make sure the "$pp_checkscript" variable points to the the "pp-checker.php" file on your webserver. For example:

$pp_checkscript = 'http://example.com/buy/pp-checker.php';

Then, when your user has finished ordering through PayPal, PayPal then talks back to your "pp-checker.php" and gives it all the information (who ordered, the email, the amount, etc.) The "pp-checker.php" verifies the information, generates a product key using the LimeLM API, then sends the product key to the user.
