we want paypal integration for our website. Right now that's working but it's not resulting into Transaction Approval True/False as it goes to paypal first but we need real implementation so that we can keep our front-end and processes from paypal in backend and value is properly returned as True or False. If transaction is approved, our software should start downloading and since we are not allowing to create any user details as of now, the same link should not be repeated and user should not realize the path of FTP and if the same user tries the same link after a day or two, it should not work (it's working with our code, we created a session which works only til the browser is open so you can adopt that)
