Do I need to change my IPN URL in PayPal because I applied my own domain name?

If you have set up IPN using the URL with your subdomain name, you do not need to change that information if you apply your own domain name.

On the other hand, if you set up IPN using the URL with your domain name and you unapply your domain name or your domain name expires then IPN will not work. Due to this, we recommend that you use your  Redframe name URL when setting up IPN.
