djp1988 Posted October 30, 2009 Share Posted October 30, 2009 Hi all, I am trying to change the price of an article for a friend on his online shop, he uses paypal to accept payments, but I searched his database and his scripts, and I can't find the info concerning the price, is this stored on his paypal account?I would like to know if i have to ask him for these details or if I've missed something...I've never used paypal before as a payment solution on website, so, I don't really know how it works.I think the amount is passed as a hidden input value from the form, but in that case I can just change this amount and put 0, what stops me doing this ?

justsomeguy Posted October 30, 2009 Share Posted October 30, 2009 It's usually sent to PayPal in the form like you mentioned. PayPal will usually send a request back to the server to validate the data that came through, to make sure the server actually sent everything. There should be another page that PayPal uses to verify that information. If you had access to the PayPal merchant account you should be able to see the URLs that are set up for that.
