How to register a facebook achievement successfully without url/host errors
===

Iam trying to register a facebook game achievement using 

    https://graph.facebook.com/445683645462153/achievements?achievement=https://gameafrica.herokuapp.com/server/goldmedal.php&access_token=[accessToken]&display_order=1

I only get this 

    {
       "data": [
          
       ]
    }

I have also tried to do the same using 

    curl -F 'achievement=http://gameafrica.herokuapp.com/server/goldmedal.php'\
           -F 'display_order=1'\
           -F 'access_token=[accessToken]'\
           'https://graph.facebook.com/445683645462153/achievements'

of which I get the error 

    curl: (6) Couldn't resolve host 'achievement=https:'
Please help me register the achievement successfully
