The SI-TSA (Slovenian Time Stamping Authority), an issuing authority for time stamps, is part of the infrastructure of the Certification Authority at the Slovenian Ministry of Public Administration. The SI-TSA issues trusted time stamps intended for use by public administration institutions. In the future, they will also be available to businesses and other end users.
The SI-TSA Timestamp API can be accessed using SOAP calls issued in XML format. The SI-TSA website and the API documentation are provided in both Slovenian and English.
