Merchants needing a list of IP addresses where Segpay postbacks originate (so the IPs can be whitelisted in your system) could always request the most current list using our SRS/web service system. Going forward, this is the only way to get the list. For instructions, search for “Get Postback IP List” in our SRS documentation.
If you’ve been getting the IP list from a link to a text file that we’ve provided in the past, please be aware that we no longer keep that file updated with the latest IPs. Access to the file will be removed very soon, so now is a good time to get familiar with the SRS/web service request mentioned above, if you aren’t already.
As always, please contact firstname.lastname@example.org if you have questions.
