Cardinal Commerce Infrastructure Change

Please be aware of upcoming infrastructure changes being made by Cardinal Commerce that may require action on your part.

Cardinal Commerce are migrating their endpoints to new IP addresses. If your integration connects directly to Cardinal (sometimes referred to as a Songbird integration) and you use IP allow-listing in your firewall or network configuration, you will need to add Cardinal's new IP addresses before their cutover date to avoid disruption to your 3D Secure processing.

Cardinal have published full details of the new IP addresses and the change here: https://cardinalcommercecorporation.statuspage.io/incidents/6x4q77c2yg33

Planned testing schedule (all times approximate, starting ~10:00 AM ET / 15:00 UTC): • 11 March – Flash test (~15 minutes) • 18 March – Medium duration test (~30 minutes) • 25 March – Extended test (~60 minutes) • April – Permanent DNS cutover in production

If you do not connect directly to Cardinal, or do not use IP allow-listing, no action is needed.

If you're unsure whether this affects you, please share this email with your technical or network team.
