IPN Verification Postback to HTTPS Microsite
Merchants and partners use Instant Payment Notification (IPN) to receive notifications of events related to PayPal transactions. The IPN message service requires that you acknowledge receipt of these messages and validate them. This process includes posting the messages back to PayPal for verification. In the past, PayPal has allowed the use of HTTP for these postbacks. For increased security going forward, only HTTPS will be allowed.
The ipnpb.paypal.com and ipnpb.sandbox.paypal.com endpoints only accept HTTPS connections. If you currently use www.paypal.com, you should move to ipnpb.paypal.com when you update your code to use HTTPS.

When used for IPN postbacks, www.sandbox.paypal.com will only accept HTTPS connections.

To avoid any disruption of service, you must verify that your systems are ready for this change by September 30, 2016 |
NOTE: | In addition to requiring HTTPS, PayPal is also upgrading the security standards of all external endpoints. You should verify that your current systems support these requirements. More details can be found on the SSL and TLS microsites. |

- Why is PayPal making this change?
PayPal is upgrading all external endpoints used by merchants and partners to make programmatic connections. One of these changes is only allowing the use of HTTPS when connecting with PayPal systems to ensure that all information is securely transmitted. IPN messages contain sensitive information about your customers and their transactions that should only be passed securely.
- What are the upgraded security standards that PayPal is moving to for all external endpoints?
PayPal is upgrading all of its external endpoints to the latest industry standards:
HTTP 1.1 or newer
HTTPS only
TLS 1.2 or newer only
2048-bit, SHA-256 certificates signed with VeriSigns G5 root
For more information, please reference the SSL and TLS microsites.
