The RESTful Api Plugin for VASCO provides an application program interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data.

The Api documentation is created by Swagger UI[1] and can be accessed (after the successful start of the plugin) using http://localhost:4711/vasco/api-doc


The default port for the API service is 4711. An different port can be specified in the registry with a dword value RESTApiPort under HKEY_CURRENT_USER\Software\Fraunhofer\VASCO

Example: The following RegEdit export will set the port to 4719:

Windows Registry Editor Version 5.00


Since the plugin registers a service for a specified URL, the user needs to have the appropriate right to do this. The administrator can provide the VASCO user the necessary right using netsh http add urlacl.


netsh http add urlacl url=http://+:{port}/vasco user={DOMAIN\user}


Once the Plugin is configured, it can be used by accessing http://localhost:4711/vasco/v1/version in your web browser.
