Hello, I'm a developer and new for PayPal technology and this community. I need some help, please. My question: About IPN listeners Endpoint In this official document, endpoint URL for IPN lisners is following: https://ipnpb.paypal.com/cgi-bin/webscr (for Live IPN) BTW, The URL of the PayPal client library we're using points to https://www.paypal.com/cgi-bin/webscr, not the one above. According to the PayPal's API endpoint list page, it seems we can use both "ipnpb.paypal.com/cgi-bin/webscr" and "www.paypal.com/cgi-bin/webscr". I would like to know how long this URL (www.paypal.com based endpoint) will be available. I could not find the information when the URL will be obsoleted and closed.
