BIDDER MUST BE ABLE TO COMPLETE THE WORK TODAY.
You're to fully integrate Paypal IPN in this website: [url removed, login to view]
1.) Currently, it's just handling normal payments and users are redirected to Paypal and that is all. Sometimes, payment is going through but not the data - and these are causing problems for our users. We want to fully integrate Paypal in our system.
2.) You also need to encrypt Paypal button/form: so far, it is not, we can see that in the HTML source of the code and that means a user could modify that data.
3.) To use Paypal IPN (via notify_url) so that the payment results (amount, success/failure etc) cannot be tampered with.

Hello, If you choose me now I can finish today. Paypal IPN is there to prevent tampering. If the user changes the paypal button, the IPN will show it and then we can see that the user tried to change it.
