Hi guys I am now currently trying to implement Paypal payment in the website. I used the form provided by Paypal and it worked. However, I wish to make the payment details more secured by checking the POST details against the database first before posting to Paypal. I have been reading the internet for the past few days about how to do it, but till now I am still very confused in doing it. The thing that I read about is IPN (Instant Payment Notification). Is there anyone able to guide me on how to do it? Or have I been reading the wrong thing for the past few days?
