I have created an app to post a photo in Facebook. I want to delete those photos posted by my app. I have read the documentation and found that Facebook allows Apps to delete the photos posted by them. Click Here This link gives the answer for my question.
You can delete photos for a user posted from your app by issuing an HTTP DELETE request to PROFILE_ID/photos with the user access token or app access_token.
But how to issue a HTTP delete request. Don't we need the photo id for deleting the photo?
I have tried to send a HTTP DELETE REQUEST as mentioned above using PHP SDK. But I got an error like this
Fatal error: Uncaught GraphMethodException: Unsupported delete request.
This is how I send the request
$response = $facebook->api('/me/photos/','delete',array("photoid" => "$photoid"));
Please help
In order to delete a photo that was created by the application, you have to make a DELETE request to a url like this:
https://graph.facebook.com/PHOTO_ID
I'm not sure why the documentation states otherwise (might be worth a bug report).
So in the PHP SDK, it would look something like this:
$facebook->setAccessToken( YOUR_APP_TOKEN );
$response = $facebook->api( '/PHOTO_ID', 'delete' );

I am currently developing an app with which visitors of an event can take pictures using a webcam and upload them to Facebook using an AS3-application. I know I can connect to Facebook, because I can log the user out using the API and I can get all the information. The problem is that I can't post to their wall for some reason. I keep getting the following error:
error #2032: stream error. url: https://graph.facebook.com/********/feed
I use the following code to post to Facebook:
private function postFB(e:Event=null):void {
var _params:Object = new Object();
_params.uid = Facebook.getAuthResponse().uid;
_params.access_token = Facebook.getAuthResponse().accessToken;
_params.message = "I was at the Thanksgiving Day Event.";
//_params.picture = _bitmap;
Facebook.api("/me/feed", postComplete, _params, "POST");
}
As I've said before, I know I am connected to facebook because if I change "POST" to "GET" in my api-call, I get all the information of my account. I have the correct permissions as far as I know (read_stream, publish_stream, user_photos). I use GraphAPI_Web_1_8_1.swc as an api.
The documentation on the entire api is very poor, so I am trying to figure out the problem. It's been a few years since I've tried any of this, so my code has probably aged too far by now. So, any ideas what I'm doing wrong?
publish_stream is deprecated (since years?), you need to use publish_actions.
If that does not work, make sure the Access Token includes all the permissions, you can test this in the Debugger: https://developers.facebook.com/tools/debug/
Side note: AS3 is not getting used very often anymore, the last version of the the AS3 SDK is from 2011. It may be a good idea to switch to the JavaScript SDK.
I created and APP on the Facebook.
Now I am trying to post a comment on the user's timeline using the Graph API but I cannot undestand what I need to do.
I already authorized the Application (I authorized this permissions: 'user_status,publish_stream,user_photos,email').
If I look on my profile -> privacy I can see that the APP can:
This app can: Post on your behalf
This app may post on your behalf, including status updates, photos and more.
Last data access:
Basic InformationToday
See details · Learn more
Posts on your behalf:
Who can see posts this app makes for you on your Facebook timeline?
Public
Notifications:
When to notify you?
The app sends you a notification
So this part seems OK.
On my application I do the following to try to post somenthing on my timeline (I need to post it when I am off line).
1) GET : https://graph.facebook.com/oauth/access_token?client_id=APPID&client_secret=*APP_SECRET*&grant_type=client_credentials
RESPONSE:
access_token = 422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk
2) GET: https://graph.facebook.com/search?q=myemail&type=user
RESPONSE:
_"error":_{
______"message":_"A_user_access_token_is_required_to_request_this_resource_",
______"type":_"OAuthException",
______"code":_102
___}
But reading the documentation (https://developers.facebook.com/docs/reference/api/#searching) it seems that this request does not need any kind of access token.
I also tried to add the access token, but the result is still the same.
3) I know my facebookid so I tried to use it directly:
POST: https://graph.facebook.com/100001139132403/feed
ARGUMENT:
access_token=422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk,
message=Hello
RESPONSE:
"error": {
"message": "(#200) This API call requires a valid app_id.",
"type": "OAuthException",
"code": 200
}
}
So I tried to add client_id=APPID and app_id=APPID, I tried to put one, the other and also both arguments as GET or POST but nothing changed.
I checked the APPId ad it is correct.
Do someone have any idea?
Thank you!
You cant simply generate a user access_token by querying to a URL. What you did gives the App access token and as the error say, you are trying to do something, that needs user access_token.
Refer and implement this : https://developers.facebook.com/docs/howtos/login/server-side-login/
And use that access_token for the rest of the processes.
I have setup the facebook javascript sdk to initialize a friend invite dialog to send requests to friends. Clicking on the invite in Facebook, brings the user back to the site.
The query string has any and all request_ids that have not been handled (deleted).
I am following the documenation listed at the FB developers site here which states:
JavaScript SDK:
FB.api(requestId, 'delete', function(response) {
When they are returned to my site, the querystring has a request_ids parameter:
example: www.mysite.com/somepage?request_ids=0493834050
my Javascript code looks like this:
FB.api(requestIds[i], 'delete', function (response) {
console.log(response);
});
But the error I get is:
ERROR
code: 104
message: "An access token is required to request this resource."
type: "OAuthException"
All I want to do is delete the request ID. before I was even running the above code, the querystring was building up with every submitted request. It does appear they have been removed, because the querystring is reduced down to a single request id. But I am still uncertain it has been handled properly.
NOTE I am not using the Graph version - as I have not setup Graph on the app settings in Facebook.
I have the Facebook C# sdk - if someone has an easy way to do this here. I have tried the following with the same results.
var fbClient = new FacebookClient(accessToken)
fbClient.Delete(requestId);
I don’t see what’s possibly unclear about the error message – you need a valid access token to be able to delete requests, but by the looks of it you don’t have one.
So you’ll either have to have the user connect to your app in order to get an active access token for him; or you have to do it using your own app access token (but that’d have to be done server-side then, because you don’t want to transfer your app access token to the client side).
I'm making a simple Facebook app that posts updates to the user's timeline using node.js and Facebook's Open Graph API. Even though I can see the posts I make using the OG API on my timeline (and it has the globe icon identifying that it's a public post, see pic below), none in my FB friend network can see it.
Here's a screenie of a public post I made via OG API showing up on my timeline, along with a post from a 3rd party app (Pool practice) for comparison:
Now here's the screenie of my friend's timeline showing only the Pool Practice post, the post from my app is nowhere to be seen...
I've checked the app settings and permissions as well as the OG API options, but haven't seen anything that points to how I can solve this problem. Here's the node.js code I'm using to post the updates:
// app permissions set to 'publish_actions' and 'publish_stream'
// I do the auth dance here to get the access_token and store it in session as fb_token
var request = require( 'superagent' ); // module from TJ Holowaychuk similar to "request"
request
.post( 'https://graph.facebook.com/me/feed?access_token=' + req.session.fb_token )
.send( { message: 'posting via node.js' } )
.set( 'Content-Type', 'application/x-www-form-urlencoded' )
.end( function( response ) {
log( response );
});
The code above works and the post shows up on my timeline, but no one else is able to see it.
Anyone know a way out of this?
you need to submit each action for Facebook validation before your friends can view it. Only users defined as developpers for the app are allowed to view those timeline messages.
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 !
