The only connections from Maksekeskus to merchant systems are the asynchronous notifications sent to the Notifications URL (defined in the Merchant Portal under API Settings).
The origin IP addresses of such notification requests may change in time without prior notification. Therefore it is not recommended to apply IP restrictions on incoming requests to the Notifications URL.
However, if needed, the current IP addresses are the following:
- LIVE environment: 126.96.36.199
- TEST environment: 188.8.131.52
