Support » Plugin: WordPress Simple PayPal Shopping Cart » PayPal IPN Reminders

  • Resolved evildoer


    I realize you have addressed the IPN issue in the first forum post – but it is 4 years old now and my client keeps receiving alerts (see below) from PayPal and is fretting over them. Is there any new IPN concerns here ? I installed PP Cart in 2009 and has been working fine. Can I tell my client she has nothing to worry about ? Can you explain in layman’s terms why the IPN alerts don’t apply to the Simple PayPal Cart plugin ?



    Reminder: Important information about Instant Payments Notification (IPN)

    As a reminder, communicated through email in the first week of December 2020, PayPal is expanding the Instant Payments Notification (IPN) infrastructure used to notify merchants about events related to the status of PayPal transactions. This change has added seven new IP addresses from which IPNs are being sent since January 18, 2021.

    Below are all of the IP addresses that are being used for IPN. (New) (New) (New) (New) (New) (New) (New)

    Call to Action

    If you are implementing any Access Control List (ACL) or filters on IP addresses for the IPNs received from PayPal, we request that you add all the aforementioned IP addresses before May 3, 2021.

    Doing so will help avoid missing IPNs from PayPal. If you have any further questions about this migration activity, please feel free to reach out to Merchant Technical Support (`

    Hi, thank you for reaching out to us. I have submitted a message to the developers to investigate further your request/suggestion.

    Kind regards

    Our plugin doesn’t use the IP address for IPN. So this won’t have any impact on this plugin. You can ignore this.

    If you want to, you can check with your hosting provider to make sure they don’t have any firewall that will bock IPN notification coming from those new IP addresses.
