Answer 2

1. If you don't already have a developer account, go to https://developer.paypal.com/ to get a business account.

2. Sign in under the Business account

3. More>settings>my selling tools>instant payment notifications---update>choose IPN settings

Answer 3

Profile > My selling tools > Instant Payment Notification.
You can also set the IPN URL on a per-transaction basis, in which case you don't need to set it up in your profile, by setting <input type="hidden" name="notify_url" value="http://...."> in your PayPal Website Payments Standard button.

Answer 4

No this no longer exists, so i believe you have to use answer 1, and dynamically set the URL. Paypal needs to update their website documentation better.
