Resolved
Internal system

Between 13:52 and 15:05 CET today (2026-09-03), we experienced a system disturbance affecting the following API endpoints:

  • api.smsteknik.se/send/v1
  • api1.smsteknik.se/send/v1
  • api2.smsteknik.se/send/v1

During this period, some users may have experienced authentication errors or unexpected user settings when making API calls.

The issue was fully resolved at 15:05 CET, and all services are now operating normally.

We apologize for any inconvenience caused and appreciate your patience.

Disturbance
Disturbance – inbound traffic +45

2026-07-31 – Update: The Reply Module “Svarsmodul” is now functioning as expected, similar to how it worked previously.
The service has been restored and incoming messages should now be received and processed normally.

Thank you for your patience and understanding while we worked to resolve the issue.


2026-07-20 12.05 – Update: An update was made Friday July 13 to introduce new +45 numbers into the Reply Module “Svarsmodul”.
There is a process started to migrate the old +45 numbers to a new carrier in Denmark but due to vacations there and at the old carrier we have currently no updates on when this might be finalized.

We do know that no incoming SMS to our old +45 numbers are saved or possible to restore due to the termination of those numbers at the old carrier.

2026-06-30 11:00 – Update: We have identified the issue causing the service disruption in connection with the affected operator.

Our teams are continuing to work on finding and implementing a solution as quickly as possible. Inbound traffic and related services may still be affected while this work is ongoing.

We apologize for the inconvenience and appreciate your continued patience. Further updates will be provided as soon as more information is available.
