This page lists different measures we take to maintain security and service levels. Please read carefully and follow the instructions, especially where changes may happen any time. If you do not update your settings when a change occurs, you might risk your Barion implementation's ability to work properly or at all.
It makes sense to limit the range of IP addresses where the merchant's server accepts callback requests from, although you must be aware that the IP addresses can change.
The callback request currently originate from the following IP addresses:
Legacy IP addresses until 2022.09.26
IP address(es) - sandbox environment
- 126.96.36.199 from 2022.09.05.
IP address(es) - production environment
- 188.8.131.52 from 2022.09.26.
If the IP address changes, we publish the list of new IP addresses here and notify our developers and merchants in the Facebook group (See: Getting support) and in a newsletter, sent to the merchant's e-mail used at registration.
Barion API Calls
We recommend that you use Domain Name Service (DNS) results to determine the IP addresses of our API servers. We may change records we do not provide notification of changes.
All communication with the Barion system must be done using TLS v1.2 and above - former encryption standards (SSLv3, TLS1.0 etc.) are not supported.
