For further operations, we need session ID which is specified in the field eid. In our case it is d1cb60897768780f846df7ab2400eb5f.

To stop working with Wialon and logout from the system, deactivate the session making the following request:

https://hst-api.wialon.com/wialon/ajax.html?svc=core/logout&params={}&sid=d1cb60897768780f846df7ab2400eb5f

Response:

{
	"error":0
}

Such result tells us that the exit was successful.

Parameters of this request as well as the returned value are described in the chapter Logout.
