To invoke APIs, it is possible to specify an API key called 'authKey' (For example: c6fe9f2e-43ec-4fbe-b849-7ec361975d6c). If not specified, the user will be identified as 'Guest'. The authKey will be obtainable after a registration procedure directly from the website, currently not available.

You can specify this key either as a query string parameter or as an HTTP header in order to allow users or client applications to access information or services.
