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.
As of 2017.11.23 the callback request will come from this IP Address: 184.108.40.206
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.
