General / Login to the system

Login, Digest Access Authentication (DAA)

Before a command can be called in the ITC appliance, a login is mandatory. The only exception is the request of system information.

Authorisation at the ITC appliances is carried out via Digest Access Authentication (DAA) according to RFC 2617, whereby session recognition runs outside the usual digest implementation. It is carried out by means of a cookie AUERSessionID (15-character value) from the web server of the ITC appliance, in the first successful login. If this cookie is not transferred by the application, the web server requests a new authorisation by means of Digest Access Authentication with each call. Please note that another session is then created. Currently, the web server supports a maximum of 100 sessions. If this value is exceeded, the oldest participant sessions in the Web server of the ITC appliance are deleted.


The following commands are called exclusively via https. The individual commands are appended to the URL, e.g.


All responses from the system are made with the content-type application/json (charset=utf-8). The individual data records of a type are separated by a comma. From version 2 of the API, the version of the API is displayed in the http header with the flag “X-AppVersion”.
