I found it how to get all times with the following code:

{ "version": "2.0", "method": "cmdb.objects.read", "params": { "filter": { "type_title": "LC__OBJTYPE__OPERATING_SYSTEM" }, "apikey": "2i30sgvmvl", "sort": "ASC" }, "id": "1" }

Thanks it works.! I was struggeling with cmdb.object.update, but this was not working ofc.

Many thanks.

One more question is there are English documentation in pdf?
