Security Measures

Introduction

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.

Callback

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:

40.69.88.149
52.169.80.55
40.69.88.240
13.79.241.141
52.164.220.205
52.138.142.128
52.138.141.52
51.104.153.241
20.54.0.121
20.54.2.121
20.54.3.63
20.54.3.71
20.54.3.182
20.54.3.253
20.54.4.138
20.54.4.161
20.54.5.2
20.54.5.86
20.54.5.146
40.113.73.229 NEW (2022.09.26.)
20.223.214.216 NEW (2022.09.26.)

IMPORTANT

The IP address of the callback request may change any time for security reasons.

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.

Encryption

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.
