Oh, how sensitive you are!
As you don’t mention that you checked the section. It lacks of information to understand the case correctly; It is just like the generic word “not working” in another question. If you don’t see the related optional parameter, it may be simply that the feature is not available via our endpoint.

Regards.

I did but maybe its also just bad documented like the maximum of items to get. 😉 So maybe there is a filter, just missing in the API docu.
What kind of service is that here? On every Question you react totally annoyed!

It seems you didn’t check all optional parameters by scrolling the page down.

Regards
