When I use the API to send notification requests, they arrive as expected. However after the user follows the link and accepts the App permissions, the notification persists.
Is there some additional call I need to make to clear the notification? I know it auto expires after some time, but that doesn't seem entirely satisfying.
Am I missing something, or is this really not doable?
This is how you delete app request when users accept an app invitation.
When user accepts an invitation i.e. comes to your application canvas page by clicking on app request notification, Facebook sends comma separated ids in "request_ids" parameter. You can get this requests and delete it using graph api like this :
Here I am deleting the last request id :
$ids = $_GET['request_ids'];
$id_arr = explode(",",$ids);
$count = count($id_arr);
$delete_url="https://graph.facebook.com/".$id_arr[$count-1]. "?access_token=" . $token . "&method=delete";
$result = file_get_contents($delete_url);
echo("Requests deleted (true or false) ?" . $result);
Note request_ids field may contain multiple request id if he has been invited multiple times. I am not sure but you may need to delete all.

So I'm trying to setup a bot for the new Facebook Messenger API.
I'm following the quickstart.
I setup the webhook ok, and see it in my webhooks,
I called this:
https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=%3Ctoken%3E
and it did not throw any errors,
But when I go to the Page that I generated the access token on, and send a message, it does not call my webhook.
I check the httpaccess, and it does not call it.
Any way to debug this or any ideas?
Also, one thing I'm still puzzled over is how to support managing multiple pages from one Facebook app? Anyone know the answer to this, or do you need to create anew app and get permission for every page?
I have recently worked with the new chat bot API and there's a lot that can go wrong. So, here are some Ideas.
Make sure you've verified your webhook under the product settings tab.
subscribe your app to the page using your page access token. It returns {"success" : "true"} if everything goes right.
Important
Make sure the Facebook user from which you're sending the message is listed as the Admin or Developer or Tester in your app roles (https://developers.facebook.com/apps/YOUR_APP_ID/roles/). Messages from other users won't work unless your app is approved and publicly released.
Have you received any call back from the facebook api ? or is it just the messages? Take a look at the logs of your web server and check if you're getting any hits on the webhook. Also check the error logs.
Try hitting your webhook manually and see if it responds. You can use
curl to generate a manual request. This is what the request from
Facebook looks like:
Command:
curl -i -X POST -H 'Content-Type: application/json' -d '{"object":"page","entry":[{"id":43674671559,"time":1460620433256,"messaging":[{"sender":{"id":123456789},"recipient":{"id":987654321},"timestamp":1460620433123,"message":{"mid":"mid.1460620432888:f8e3412003d2d1cd93","seq":12604,"text":"Testing Chat Bot .."}}]}]}' https://www.YOUR_WEBHOOK_URL_HERE
So my issue was I was calling GET when trying to subscribe instead of POST
https://graph.facebook.com/v2.6/:pageid/subscribed_apps?access_token=:token
GET will return the current subscriptions (empty {[]}), POST returns {"success" : "true"}
Some other gotchas I hit were,
the examples use https://graph.facebook.com/v2.6/me/.. but I seemed to need to use, https://graph.facebook.com/v2.6/:pageid
the access token is the messenger access token, not your API access token
if your webhook throws a error, Facebook will stop sending you messages for a while
One thing I'm still puzzled over is how to support managing multiple pages from one Facebook app? Anyone know the answer to this, or do you need to create anew app and get permission for every page?
Another thing which can prevent some responses from being sent to your webhook is when a message type gets blocked in a queue.
If a particular message type is delivered to your webhook but doesn't receive it's 200 response within 20 seconds it will keep trying to send you that message again for hours.
What's more facebook messenger will stop sending you any more of that message type until the first one has been acknowledged. It essentially puts them into a queue.
In the meantime, other message types will continue to send fine.
This happened to me when I accidentally introduced an undeclared variable inside my code which handled standard messages. It meant that postback messages all worked fine, but quick replies and normal messages would never get sent to my webhook. As soon as you fix the error, they all come piling through at once.
As mentioned by others, using a service such as POSTMAN to send messages to your webhook is a great way to find this kind of errors, otherwise, messenger just fails silently.
Exluding of your bot rout from CSRF verification can help if you use framework. This helps for me (Laravel 5.4, app/Http/Middleware/VerifyCsrfToken.php):
protected $except = [
'/your_bot_route'
];
I too had the same issue when I was working on a bot couple of days ago. Followed this gist and modified the code as below, and everything is working fine.
public function index()
{
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
// Set this Verify Token Value on your Facebook App
if ($verify_token === 'MyVerifyToken!') {
echo $challenge;
}
$input = json_decode(file_get_contents('php://input'), true);
// Get the Senders Graph ID
$sender = $input['entry'][0]['messaging'][0]['sender']['id'];
// Get the returned message
$message = $input['entry'][0]['messaging'][0]['message']['text'];
//$senderName = $input['entry'][0]['messaging'][0]['sender']['name'];
$reply="Sorry, I don't understand you";
switch($message)
{
case 'hello':
$reply = "Hello, Greetings from MyApp.";
break;
case 'pricing':
$reply = "Sample reply for pricing";
break;
case 'contact':
$reply = "Sample reply for contact query";
break;
case 'webinar':
$reply = "Sample reply for webinar";
break;
case 'support':
$reply = "sample reply for support";
break;
default:
$reply="Sorry, I don't understand you";
}
//API Url and Access Token, generate this token value on your Facebook App Page
$url = 'https://graph.facebook.com/v2.6/me/messages?access_token=MYACCESSTOKEN';
//Initiate cURL.
$ch = curl_init($url);
//The JSON data.
$jsonData = '{
"recipient":{
"id":"' . $sender . '"
},
"message":{
"text":"'.$reply.'"
}
}';
//Tell cURL that we want to send a POST request.
curl_setopt($ch, CURLOPT_POST, 1);
//Attach our encoded JSON string to the POST fields.
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
//Set the content type to application/json
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
//Execute the request but first check if the message is not empty.
if (!empty($input['entry'][0]['messaging'][0]['message'])) {
$result = curl_exec($ch);
}
}
Note : Ensure the user roles within the application page to get the responses from the web hook. I have set Administrator, and Tester user. Only there were able to get the responses. Other users will get once this is published. Also, change verify token, and page token accordingly.
There is an option that is asked while publishing the app about the number of business this bot going to be used by. But I have no idea how to use it. Still searching that though.
If you still can not solve your problem, try to check and update your Privacy policy link.
I updated worry link to Privacy policy, and Facebook show 404 error even the webhoob is verified...
You can link multiple pages to your app, under Add or Remove Pages tab in your Messenger Settings
I need to keep a track of users referring other users to my website. So i want whenever a user invites his friends from facebook, the invitation link to contain his userid. Is it possible to send invites with random urls.
For eg : Right now the user gets the invitation link for http://example.com because that's what i have specified in my app site url.
I want the invitation link to be http://example.com?referrer=joe
I want the invitation link to be http://example.com?referrer=joe
And “joe” would be who or what here? If it’s the user sending the request – you have his id already, it’s in the request object details under from.
If you want to pass any other referential data – the Requests dialog has the data parameter for that. You can put any text data in there, up to 255 characters long. And when the user follows the request, you will get the request id[s] they are acting upon – and then you can read the request details from the API, and you will get that value you put into data back from there as well.
See docs: https://developers.facebook.com/docs/reference/dialogs/requests/ and https://developers.facebook.com/docs/requests/
Imagine, that you have JS function:
function invite(){
//number from 0 to 9
var i = Math.floor((Math.random()*10));
//get random param
var param = arrayOfDefinedParams[i];
//define request URL
var requestUrl = "https://www.facebook.com/dialog/apprequests?app_id=<APP_ID>&message=<YOUR_MESSAGE>&redirect_uri=<URL_SET_IN_APP_DASHBOARD>/?param="+param;
//show modal window with request URL and random param
myWindow=window.open(requestUrl,'','width=400,height=300');
myWindow.focus();
}
All you have to do now, is binding invite() to onclick event on any element ;)
When a request is sent using the new fbjs requests 2.0 on Facebook:
1 - a notification is shown under the globe icon in the header
2 - a incremental number is shown next to the app name on the left menu
If the user clicks the notification, request_ids=123... is appended to the url. This can be used to clear out the request. If they navigate to the app another way such as the left menu, the requests are passed. So if the user skips over the notifications, they accumulate a lot of outstanding requests.
Is there a way to get all outstanding requests for a user without relying on them clicking the notifications?
To retrieve all the users outstanding requests you can make a call as follows :
$facebook->api('/me/apprequests/');
You can retrieve all the data for all the requests (for your application) into an array and remove them from facebook.
// Retrieve ALL request-2.0's for user
$res = $facebook->api('/me/apprequests/');
$requests = $res['data'];
foreach ($requests AS $request){
echo 'Deleting '.$request['id'] . '<br/>';
$facebook->api('/'.$request['id'].'/','DELETE');
}
Now you have all the users outstanding requests in $requests and you can act accordingly.
Facebook's real-time updates docs now say that you can get the feed for a page:
You can subscribe to the page's feed in the same way you subscribe to
a user's feed - the subscription topic should be 'user' and the
subscription field should be 'feed'
My understanding of this is that I need to post to the graph API to subscribe as such:
curl -d \
"object=user&fields=feed&callback_url=$CALLBACKURL&verify_token=$SECRET" \
"https://graph.facebook.com/$PAGEID/subscriptions?access_token=$OAUTHTOKEN"
(This is a bash script.) Here $CALLBACKURL is set up correctly following their example code. (At least I think it's correct -- I can successfully add subscriptions with it.)
The $OAUTHTOKEN is the one for my Facebook App.
And the $PAGEID is the facebook object id of the page I'd like to get realtime updates for.
When I do this, the call appears to work -- no error message. My callback gets called. But I certainly don't get notified when something happens on the page's feed.
So what's missing? Does the page need to install the app whose oauth token I'm using? Or do I somehow need to get an oauth token for the page itself by logging in as the page?
I do not know if this can help you but I'll tell you where I am for real-time update page feed:
(permissions : manage_page,offline_access,read_stream)
your application must be linked to the page (then install the application but not required to have a tab ex. create tab https://graph.facebook.com/PAGE_ID/tabs?app_id=APP_ID&method=POST&access_token=PAGE_ACCESS_TOKEN and delete tab
TAB_ID=PAGE_ID.'/tabs/app_'.APP_ID;
https://graph.facebook.com/TAB_ID?method=DELETE&access_token=PAGE_ACCESS_TOKEN)
function page_access_token($page_id,$access_token){
$page_token_url="https://graph.facebook.com/" .
$page_id . "?fields=access_token&" . $access_token;
$response = file_get_contents($page_token_url);
$resp_obj = json_decode($response,true);
$page_access_token = $resp_obj['access_token'];
return $page_access_token;
}
function page_tabs_create($page_id,$app_id,$page_access_token){
$page_settings_url = "https://graph.facebook.com/" .
$page_id . "/tabs?app_id=".$app_id."&method=POST&access_token=" . $page_access_token;
$response = file_get_contents($page_settings_url);
$resp_obj = json_decode($response,true);
return $resp_obj;
}
function page_tabs_delete($tab_id,$page_access_token){
$page_settings_url = "https://graph.facebook.com/".$tab_id."?method=DELETE&access_token=" . $page_access_token;
$response = file_get_contents($page_settings_url);
$resp_obj = json_decode($response,true);
return $resp_obj;
}
Subscription: to subscribe must be like a "user" and therefore object = user fields = feed but you have to add new fields because otherwise it receives the comments and likes the wall so you must add "status" in order to receive the articles posted (my problem is to get other content such as links I have managed to add "link" as fields but I am not receiving notifications when a link is posted)
$param = array ('access_token' => $ access_token,
'object' => 'user',
'fields' => 'feed, status, link'
'callback_url' => 'http:// ******** fbcallback.php'
'verify_token' =>'***********',
'include_values' => 'true');
POST
https://graph.facebook.com/APP_ID/subscriptions
my English is not very good but I hope it will help you, on my side I'm still looking for really all updates to the wall (links, video ...)
I have been researching on this and i am getting the pushes for pages too.
while subscribing make sure that object = user and fields = feed, status is present.
Make sure that application is added to your page, then only you will receive the update.
Response received from facebook is as below :-
{"entry":[{"id":"*******","uid":"*****","time":1332940650,"changed_fields":["status"]}],"object":"user"}
where **** is my pageId.
The above push is received on adding a new post , as you can see the changed_feild is status , but when we post on wall the changed_fields comes as feed. Below link helped me in receiving pushes for the page.
http://bugs.developers.facebook.net/show_bug.cgi?id=18048
Firstly, subscription to real-time update for page/feed doesn't work.
See: http://bugs.developers.facebook.net/show_bug.cgi?id=18048
Does the page need to install the app whose oauth token I'm using?
Yes
Or do I somehow need to get an oauth token for the page itself by logging in as the page?
If i correctly understand you, you need only app access_token
https://graph.facebook.com/oauth/access_token?client_id=your_app_id&client_secret=your_secret&grant_type=client_credentials
I first started reading the docs about real-time updates thinking that it could delivery the actual data. But, as I realized, that's not the purpose.
Real-time updates are just to tell you that something has changed, and once it happens, you can call the api with the conventional method.
Also, seems like there's an error on this part the subscription topic should be 'user' and the subscription field should be 'feed'. The subscription topic, actually, should be 'page'. (Have you thought the same?)
And by subscribe on page feed as the same as user feed, means that you can get update notifications, not the data itself.
Not sure if this is a common mistake, but I'm posting it just in case.
--
Currently I'm working on a data mining tool that will need real-time updates. But first, I'm focused on the data itself, so I can't post any examples yet. (I'll edit this answer when implementing this part)
What I can say about your issue is:
1) Look that your $PAGEID isn't correct. Actually it's your APPID instead.
2) After subscribing, have your subscription appeared on the list when calling https://graph.facebook.com/<app-id>/subscriptions?access_token=... ?
3) With user subscription, does it work? Or is it just with pages?
For this you need to set up an endpoint URL that receives both HTTP GET (for subscription verification) and POST (for actual change data) requests from Facebook.
Then you should make a POST to the graph API url https://graph.facebook.com/<app-id>/subscriptions?access_token=<access_token> to subscribe, and be ready to handle the verification request.
Then to list subscriptions, just perform a GET request on the same url, https://graph.facebook.com/<app-id>/subscriptions?access_token=<access_token>, which returns a JSON-encoded content that lists your subscriptions, up to one per object type.
Before you start waiting for the notifications you should check if the URL is actually being hit or not by FB
Check The Output of Following:
"https://graph.facebook.com/".FACEBOOK_APP_ID."/subscriptions?".$appToken."&client_secret=".FACEBOOK_SECRET;
This shall return the callback_url if set correctly !
I'm developing a website with the following requirement:
Users may invite their facebook friends to visit the website
Invited friends receive a personalized URL that points back to the website (either a message, notification, request...doesn't matter)
Example flow:
1. John visits http://www.mysite.com
2. John clicks the Facebook connect button and logs in with his facebook credentials
3. John clicks 'invite friends' button. The friend selector dialog appears
4. John selects Mary and submits the invitation/request/message
5. Mary receives a link like: http://www.mysite.com?name=Mary
6. Mary clicks the link from within facebook and is redirected to the URL above
7. My site displays: "Hello Mary!", taking the name from the URL parameter
I already managed to make steps 1-4.
I'm asking about step 5. Is that possible at all? I know I can get the facebook IDs of the people selected in the multi-friend selector, and that I can make a FBQL query to retrieve the names of the people selected, but how to customize the URL sent?
Cheers,
Nacho
Well, if the user will be sending invitations for a bulk of friends then these invitations won't be "invitee unique" (As mentioned by #Jimmy). BUT you can still capture the unique "friend id" and (I suppose) name from the request itself!
What you need to do is the following:
When a friend clicks on the invitation, he/she will get redirected to the canvas page (or the bookmark page if it has been sit).
Along with the redirection you'll receive the invitation number (request id) here you can read this request and extract the "To" field from it and then redirect the friend to your website.
Something like:
<?php
if( isset($_REQUEST['request_ids']) ) {
// Requesting an application token
$APPLICATION_ID = "APP_D";
$APPLICATION_SECRET = "APP_SECRET";
$token_url = "https://graph.facebook.com/oauth/access_token?" .
"client_id=" . $APPLICATION_ID .
"&client_secret=" . $APPLICATION_SECRET .
"&grant_type=client_credentials";
$app_token = file_get_contents($token_url);
// You may have more than one request, so it's better to loop
$requests = explode(',',$_REQUEST['request_ids']);
foreach($requests as $request_id) {
// Get the request details using Graph API
$request_content = json_decode(file_get_contents("https://graph.facebook.com/$request_id?$app_token"), TRUE);
// An example of how to get info from the previous call
$to_name = $request_content['to']['name'];
// When all is done, delete the requests because Facebook will not do it for you!
$deleted = file_get_contents("https://graph.facebook.com/$request_id?$app_token&method=delete"); // Should return true on success
echo "<script>top.location.href='http://www.mysite.com?name=" . urlencode($to_name) . "'</script>";
}
}
?>

Facebook Documentation
How To: Handle Application Requests Using The Facebook Graph API
When the referred user lands on your site, you either need to know their Facebook User ID or all the information you plan to show them. It's going to be easier and more extensible to use the User ID, and to get that you'll need to get that user to install your app before you can identify them, look up their name, and say "Hello Mary!"
What I'd do here is let the referring user share a link customized for him. So if I'm A, and I'm sharing with my friends, my link would look like http://www.somedomain.com/?ref=A. I share this, my friend B clicks the link. When B gets to the install screen, he installs, and now we know B's name, and since we have the ref parameter, we know he clicked my link. (This is how Groupon and Dropbox handle referral links.)
And to answer your question more clearly, no, invite links need to be the same for each invitation you send using the multi-friend selector, so per-invitee links are not an option.
