https://developers.facebook.com/docs/apps/review/opengraph

Answer 1

the error message "You, or this app's Open Graph Test User, must have published this action at least once" means: before you require this permission, you must call the api at least once.

I have occur this kind error before. when I require publish_actions permission, the facebook tell me this:

then I used my app call /me/feed api post a feed, then the error disappeared.

if you are the owner, developers or test users of the app, you can use these api before review approval. you can add roles for app in dashboard.

On FB javascript sdk,

-* fb dashboard -> Open Graph

1. Create a story
2. List item make sure you enable the 'capabilities' features such as -tags, -user messages, -place, etc. in your action type.

-* in your js

1. call the js sdk

    window.fbAsyncInit = function() {
    FB.init({
      appId      : {YOUR_APP_ID} , // App ID
      version: 'v2.0',
      status     : true, // check login status
      cookie     : true, // enable cookies to allow the server to access the session
      oauth      : true, // enable OAuth 2.0
      xfbml      : true  // parse XFBML
    });
  };



    // Load the SDK Asynchronously
      (function(d){
         var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
         js = d.createElement('script'); js.id = id; js.async = true;
         js.src = "//connect.facebook.net/en_US/sdk.js";
         d.getElementsByTagName('head')[0].appendChild(js);
       }(document));
    }

3. Login into FB asking with these scopes

function Login()
    {

        FB.login(function(response) {
           if (response.authResponse) 
           {
                console.log(response.authResponse); // Get User Information.

            } else
            {
             console.log('Authorization failed.');
            }
         },{scope: 'user_friends, publish_actions, status_update, read_stream, manage_friendlists'});// ' user_interests, user_likes, etc.. '

    }

4. Get the logged user taggable_friends with a function such as:

var  var friendsIDarray = [];
var user_friend_list;
    function meTaggableFriends(){
        FB.api(
            "/me/taggable_friends",
            function (response) {
              if (response && !response.error) {
                /* handle the result */
                console.log(response)

                    for(var i=0; i<response.data.length; i++){

                        var data = response.data;
                        friendsIDarray.push(data[i].id);    
                    }
                    user_friend_list = friendsIDarray.join();

              }
            }
        );

5. Now, we have stored the token ids in user_friend_list for those friends we want to tag in our post and we can use an Open Graph action like this in order to tag friends:

FB.api(
                      'me/{namespace}:{action}',
                      'post',
                      {
                         {object-type}:'http://example.com/object/', // make sure to have the apropiate og:type meta set
                         place:'https://example.com/place/', // open graph page with metas for location, id for a location page etc
                         tags: user_friend_list, // the tokens ids for those friens you wanna tag and you got on previous step
                         title: 'whatever',
                         message: 'like this, you tag friends @['+ONE_TOKEN_ID_FROM_TAGGABLE_FRIENDS+'] , @['+ONE_TOKEN_ID_FROM_TAGGABLE_FRIENDS+'] etc'
                      }, 
                      function(response) {
                        console.log(response)
                      }
                );
