Facebook graph api like an external url, statistics - facebook

Question

I am using a Facebook graph api to like an external url:
Method: POST
URL:
https://graph.facebook.com/v2.1/{userId}/og.likes
Header:
application/x-www-form-urlencoded
Body:
access_token={appId}|{appSecrect}&object={"url":"{myUrl}", "title":"{myTitle}"}
It is publishing successfully, returning an Action Id.
I have 2 problems:
I can keep liking with the same user Id and it will always succeed.
I can find my url in object_url table, but link_stat and url_like do not contain any information about this url.
Another strange thing, is if I publish my url like this:
access_token={appId}|{appSecrect}&object={myUrl}
The first request throws an error "title is missing".
The second time the same request returns success.
After that for the same requests it is able to distinguish that a user already liked the url. And I have information in link_stat table.

Answer 1

I finally found the solution.
1. Create an object
This request creates an object "link" and returns an Object Id.
URL: /app/objects/website
Header: Content-Type: application/x-www-form-urlencoded
Body: UrlEncode object's json!
access_token={appId}|{appSecret}&object={
"title":"Happy event",
"image":"{img_url}",
"url":"{custom_url}",
"description":"{description}",
"data": {} }
You can read more here:
https://developers.facebook.com/docs/opengraph/using-objects
2. Like an object
This request will "like" your link on behalf of the user.
It will show in the user's timeline as "User likes a link on you Application site..".
Make sure:
1. User has granted "publish_actions" permission;
2. Your application is apprved for submission of the likes. Otherwise only administrators, developers and testers of you Application can make "likes".
For more information read this :
https://developers.facebook.com/docs/opengraph/submission-process
URL: /v2.1/{user_id}/og.likes
Header: Content-Type:application/x-www-form-urlencoded
Body: object={object_id}&access_token={appId}|{appSecret}
3. Get likes for an object
URL: /v2.1/{object_id}/likes?access_token={appId}|{appSecret}
