Socialwall: Sending Requests to Facebook and Twitter

Hi, I'm building a SocialWall on my page that'll show recent FB posts, Tweets,...

I've created my FB app and my Twitter app(in order to get the tokens), but now how to send a GET Request to Facebook Graph API to get my Access Token...? I tried curl but: Call to undefined function App\curl_init(), I tried Buzz package - Illuminate error, some function is missing...

Is there a better way to interact with Social API's? Thanks! Best Regards, Nejc
