facebook realtime subsciption API error

I'm using this link in order to add new subsciption entry:

https://graph.facebook.com/XXX/subscriptions?access_token=YYY&object=payments&callback_url=http://xxx/rlcallback.php&fields=actions,disputes&verify_token=ZZZ

For some reason, I get error:

{
   "error": {
      "message": "(#100) Invalid object. object should be url or open graph object id.",
      "type": "OAuthException",
      "code": 100
   }
}

But the object "payments" inside my link is clearly valid. What am I missing here?

Make sure you are using the correct parameters: object, callback_url, fields, verify_token...and of course the access_token.

Also (and that may be the problem in this case), you have to use POST, not GET. You can either use CURL with POST to subscribe to the Realtime API, or you just use one of the SDKs as explained in the Facebook docs: https://developers.facebook.com/docs/graph-api/reference/v2.1/app/subscriptions

Here is one example with CURL:

$appsecretProof = hash_hmac('sha256', FBAPPID . '|' . FBSECRET, FBSECRET);
$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'facebook-php');
$postData = 'object=page' .
    '&callback_url=' . urlencode('http://yourdomain.com/callback.php') .
    '&fields=feed' .
    '&verify_token=somethingfancy' .
    '&access_token=' . FBAPPID . '|' . FBSECRET .
    '&appsecret_proof=' . $appsecretProof;
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/' . FBAPPID . '/subscriptions');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
$curlResult = curl_exec($ch);

you need to specify object, callback_url, fields and verify_token parameters as your curl post parameters

example: curl -F 'object=user' \ -F 'callback_url=' \ -F 'fields=checkins' \ -F 'verify_token=' \ "https://graph.facebook.com//subscriptions?access_token=
