Parameter Description
api-version

Version number for compatibility reasons. The default value is 2.0!
jsonCompact

jsonCompact. The default value is 0. If you set the parameter to 1, the JSON will be returned in a compressed format (output on one line), not "human readable", but slightly less network traffic.

Example with the version 2.0

As of the version 2.0 of the REST Reporting API (available with WinCC OA 3.19-P002) the standard format of the response has been changed to structured JSON objects instead of flat JSON array.
