So basically, I want to be able to accept paypal payments for my web site, I used to use PayPal IPN with PHP. Well that was a few years ago and it seems things have changed. Does the IPN system not exist anymore? Do I really have to buy an SSL and use the new SOAP api? I basically just want people to be able to sign up for a recurring service and have paypal send the information about the transaction id like they used to.
