It seems that IPN is the best choice for an online merchant system with PayPal. In order to test the system I have taken the advice to set up a sandbox first. I seem to be having some problems with doing this. First of all, there is a list of types to pick: arguemax.com/sandbox/sandbox%20001.jpg From this list, I picked "Web Accept". This page asks for the "IPN handler URL". I assume this is supposed to be the URL of the page that we set up that to be used as the location where PAYPAL sends confirmation to and the page has PHP and MYSQL script to put a confirmation in the database. Anyway, I got an error message: arguemax.com/sandbox/sandbox%20002.jpg Did I do something wrong or is it the fault of the sandbox?
Re: IPN While I am unable to debug IPN for you, you should use a well working shopping cart that has a working module such as ZenCart.
