thanks, some more questions, i wish to understand the technical aspects of it
with the 2) answer, i have a couple of questions
so when the paypal ipn sends the user back to the autosignup.php AFTER he has paid, does paypal send the user back to autosignup.php with a unique key? ie:
from there you can verify those details, and once they are, verified from paypal does your script then proceed to sign them up through the ispconfig soap calls?
how DOES your script verify correctly that your user has signed up?
