Est. Budget: $50.00
I sell digital products off my website,
Someone tricked my current Paypal IPN delivering system to send them the product they bought, which is meant to be $54.99, but they changed the checkout price to $0,01 and they received the product because my website has an automated delivery system.
I need the IPN code to be amended so it checks for fraud like this, so it checks that the purchase amount is the same as it is ...
