Question

I’ve been trying to post app specific actions to wall posts but nothing seems to help. What am I doing wrong?

  oauth = Koala::Facebook::OAuth.new(CLIENT_ID, CLIENT_SECRET, "http://myurl.com/fb_auth")
  token = oauth.get_access_token(params[:code])
  graph = Koala::Facebook::API.new token
  p graph.put_wall_post("explodingdog!", {
    :link => "http://youtube.com/", 
    :caption => "Youtube",
    :actions => [{:name => "Share", :link => "http://google.com"}]
  })

You must convert actions to JSON string, using json gem this is how you will do it:

gem install json

then use to_json to convert your array to json:

 oauth = Koala::Facebook::OAuth.new(CLIENT_ID, CLIENT_SECRET, "http://myurl.com/fb_auth")
  token = oauth.get_access_token(params[:code])
  graph = Koala::Facebook::API.new token
  p graph.put_wall_post("explodingdog!", {
    :link => "http://youtube.com/", 
    :caption => "Youtube",
    :actions => [{:name => "Share", :link => "http://google.com"}].to_json
  })  

You are done 🙂
