I have now a subscription service on my site that is allowing for user to subscribe through paypal for a small amount each month. When the transaction completes the user is sent back to subscribe.php?complete=1 so they account can be upgraded but what is to stop them from typing in the url without going through paypal?

Thank you

Paypal will report to your site through a callback script. You can then save the username, and password that you can validate on your own site.
