I was wondering if there were anyways to use paypal's IPN to check if one user actually did pay another user on my website.
Basically, on my website, one user-the sender(User X) pays another user-the receiver(User Y) through paypal and then I want to know if User Y actually received the money from User X, is this possible through the IPN and whether it was a secure way to do this?
Im thinking that I send the user to the paypal link as normal with the amount in the url and receivers address and also the return url, after they pay or do not pay, then I check the receivers email from the IPN report againest the receivers email on my end and the amount also, and possibly the sender's email, then check if everything matches.
Is this a good way to do this? Is it a safe way to do this?
Any ideas on how to do this type of P2P Payment and Verification through your own website/php script?
Any help would be appreciated highly.
