Twitter API (OAuth) and openframeworks / c++

Hello, I’ve been searching and trying out for a week now, do you know any addons or working solutions to connect to the Twitter API? (which means oauth2)
In my case (app-only authentication) I only need to sign two HTTP messages in the right way (following, so I have been trying out ofxHTTP or even Poco::Net (with OAuth20Credentials), but didnt get it working (and ofxOAuth doesnt support oauth2)

Do you maybe have any suggestions, example code etc.? doesnt have to be a ready-made addon, maybe a Poco Example. Or do I underestimate how complicated that ist?
Thank you very much, I’m very desperate :frowning:

Ok! I’ve got a solution for “app-only authentication” here :sweat_smile:
