Facebook Graph API - Adding tab - facebook

Question

I am trying to add a tab trought the facebook js api, and it fails:
Login with permissions:
FB.login(function(response) {
console.log(response);
}, {
scope: 'publish_actions, manage_pages'
});
FB.login(function(response) {console.log(response);
}, {perms:'read_stream,publish_stream,offline_access'});
reading pages to get token:
FB.api(
"/me/accounts",
function (response) {
if (response && !response.error) {
console.log(response)
}
}
);
adding a tab, for example, these two methods:
a.
FB.api(
"/{page_id}/tabs/",
"POST",
{
"app_id": "{app_id}",
access_token: "{token}"
},
function (response) {
console.log(response)
}
);
I get response:
Object {success: true}
b. tried directly:
jimdoGen002.getJSON('https://graph.facebook.com/{page_id}/tabs?app_id={app_id}&access_token=token&callback=?', function(r){console.log(r)})
I get response, array with the tabs the user page has, but without my new tab.
going to the user page - no new tab.
My questions:
what am I missing? why do I get sucess but cant get the tab?
if its because the review of "manage_pages" by facebook is not complete yet - why do I get success?
if the above - how can I test manage pages BEFORE I post it to facebook review?
Can I add a tab WITHOUT an app inside? just an iframe url?
Thanks in advance,
Lior.
(to make it all simple:)
FB.api(
"/me/accounts",
function (response) {
var token = response.data[0].access_token;
var id = response.data[0].id;
console.log(response.data[0].name);
FB.api(
id + '/tabs',
"POST",
{
"app_id": {app_id},
"access_token": token
},
function (response) {
console.log(response);
FB.api(
id + '/tabs/{app_id}',
function (response) {
console.log(response)
},
{
access_token: token
},
function(response) {
console.log(response)
}
);
}
);
}
);
result:
my page
Object {success: true}
Object {data: Array[2]} - none is my app.
