PayPal payments to update database
I'm trying to do this with recurring payments, seeing if anyone has a tutorial cause I could not find one that doesn't confuse the heck out of me.
I want to update the database every month, anyone done this before? do you just send the
<input type="hidden" name="notify_url" value="www.sample.com/notify.php">
and it comes back to that whenever the payment is meet?
