Authentication Server Restart

Incident Report for fiskaly Page

Resolved

Yesterday, 29.10.2025, at 22:48 CET (21:48 UTC), we experienced an unplanned restart of our authentication service.
As a result, refresh tokens were invalidated and can not be used for re-authenticating.
In this case, please authenticate using API Secret and API Secret instead.

Please make sure your implementation uses ApiKeyAuthentication if RefreshTokenAuthentication fails with a 401 HTTP status code response.

We apologize for the inconvenience.
