IP Whitelist Announcement

Dear business partner,

Infrastructure changes will be made in order to further increase the quality of service we offer to you.

In order to avoid any problems after the work to be done, we kindly ask our member merchants, who apply the whitelist rule on their side of the IP addresses in the tables below, to whitelist our new IP addresses without removing the existing IP addresses currently used, until 20/09/2024 at the latest.

There is nothing to be done on their side by our member businesses that do not apply IP whitelist.

Until our work is completed, do not remove the IP addresses that are already used, only add the new IPs listed below. After our work is completed, we will provide you with information about the removal of old IPs.

NOTE: We kindly ask you to share this announcement with the infrastructure you currently use, 3rd Party companies and your technology teams.
