Private data from API::ISteamUser::GetPlayerSummaries

[Senky]

Hello,
I try to pull my private steam data via provided REST API, but whatever I try, it won't show my private info. Here is what I do:

1) grab api key from https://steamcommunity.com/dev/apikey
2) find my steam id from https://steamid.io (steamID64)
3) access this url: http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=<api_key>&steamids=<my_steam_id>

It always shows only public info.

Could anyone, please, try the same with his/her account to see if they can get private info?

Thanks for any answer!

The only fields I am getting:

steamid
communityvisibilitystate
profilestate
personaname
lastlogoff
commentpermission
profileurl
avatar
avatarmedium
avatarfull
personastate
realname
primaryclanid
timecreated
personastateflags
loccountrycode

I was (kinda) using this URL:

https!!!api.steampowered.commm/ISteamUser/GetPlayerSummaries/v0002/?key=[STEAM_WEB_API_KEY_HERE]&steamids=......&format=vdf
