Hi all-
> > Has anybody worked with PayPal's Instant Payment Notification?
> Not yet, but am about to.
we integrated paypal in phpauction. At paypal.com, one you register as
developer, you have access to their documentation.
That's enough to get it working.

In our implementation, phpauction set up a form with hidden fields containing
the data paypal expects to receive.
Once the user submit that form he goes to paypal and makes the payment.
In that form you pass to paypay a "Confirm" URL you want your users to be
redirected after they do the payment and a "Cancel" URL where you want your
users to be redirected if they press Cancel at peupal.
What you'll also have to do is to set up the IPN url, where paypal will POST
the transaction result in the format described in the documentation.
Once your IPN script receives the POST from paypal, it will be able to check
the transaction's result and act accordingly (tipically update some database
tables).
I cannot pass you the entire code since it belongs to the non-GPL version of
phpauction but will surelly post some pieces of code here if need it.
Cheers
Gianluca
