PayPal IPN回调仅允许在https域上使用？

Question

I am trying to make my first IPN listener to connect my site with PayPal for different actions on IPN's.

I see in the documents "PayPal no longer supports HTTP for post backs" (more details). Does it mean my site (with the ipn listener script have to be on https domain or does only mean i have to send my verify callback to paypal's "https://ipnpb.paypal.com/cgi-bin/webscr" adress and not to "https://ipnpb.paypal.com/cgi-bin/webscr"?

As I mentioned in the document, you should call the PayPal end points only with https. (Otherwise your request will be denied) Your site don't need an SSL certificate.
