I need to authorize the user ingame to make real safe requests and sends to a PHP page. Most of my tries just give page errors though.
I already made an application in Web Services settings, I have the two IDs and a redirect page, but I don't know what to do with them.

This link tells the general needed stuff, but from it I still don't know how to use it. The parameter info is too brief.

The OAuth2 links seem to work in manialink browser, although I still keep getting parameter errors. Do I need to install the webservices PHP application when I only need things from basic scope and token? Are the OAuth2 links enough to be able to authorize the user?
Example of ingame auth is hugely appreciated.
