I'm writing a facebook web app with Graph API for publishing on a page wall automatically. I'm the page administrator and I've set up the app permissions for requiring manage_pages, offline_access, read_stream and publish_stream. My app will be like twitterfeed app with something different (I've no rss feed as a source).
For the first step I call:
https://graph.facebook.com/oauth/access_token?client_id=".$app_id."&client_secret=".$app_secret."&grant_type=client_credentials
When this call return an access_token I call:
https://graph.facebook.com/100344706779072?fields=access_token&access_token=". $access_token
Here I have problems: as facebook doc says (https://developers.facebook.com/docs/reference/api/page/#page_access_tokens) I must get page_access_token in this way, but this call return only the page id..
So what I'm doing wrong?
From the facebook docs here: https://developers.facebook.com/docs/howtos/login/login-as-page/
you need to use the access token you got in the first call and make a second call to https://graph.facebook.com/me/accounts?access_token=$access_token
and you'll get a reply that looks like this:
{
"data": [
{
"name": "PAGE_TITLE",
"access_token": "PAGE_ACCESS_TOKEN",
"category": "PAGE_CATEGORY",
"id": "PAGE_ID"
},
{
"name": "PAGE_TITLE",
"access_token": "PAGE_ACCESS_TOKEN",
"category": "PAGE_CATEGORY",
"id": "PAGE_ID"
},
...
]
}

I have an application that uses Facebook login module.
I tried to get manage_page and publish_page permissions but Facebook is not giving these permission without review. So, I tried to create test user and gave him above permissions.
Then logged into Facebook with test user. Facebook is not letting test user to create facebook page.
I need to access user's pages but cannot do because I cannot create at the first place.
I got the access_token of the test user and called facebook api with following json. And then I can see my test user had created page when I login to facebook.
/me/accounts
{
"name": "Your Page Name",
"category": 2211,
"about": "Description",
"picture": "your_page_picture_url",
"cover_photo": {
"url": "your_page_cover_photo_url"
},
"classic": 0,
"city_id": 2505639
}
My goal is to get a list of user facebook friends using Facebook Graph API. At least those, who have used social authentication on my website
I have read, that after v2.0 I can get only a list of friends, if the following conditions are met:
A user access token with user_friends permission is required to view
the current person's friends.
This will only return any friends who have used (via Facebook Login) the app making the request.
If a friend of the person declines the user_friends permission, that friend will not show up in the friend list for this person.
When I get a token and check
/v2.5/me/permissions
Result:
{
"data": [
{
"permission": "user_friends",
"status": "granted"
},
{
"permission": "public_profile",
"status": "granted"
}
]
}
I am testing 2 user accounts, who are friends. I have used both for login in my web application using Facebook Login.
But when I do
v2.5/me/friends
Result:
{
"data": [
],
"summary": {
"total_count": 1
}
}
What is the reason of empty friends set?
Make sure all those friends authorized your App with user_friends too. If they only authorized without user_friends, they will not show up. The response looks like it worked correctly.
Sidenote: It is not allowed to have 2 user accounts on Facebook, you can only have one account - with your real name.
I have setup realtime facebook update for both user and page. Whenever user updates his status, I get request on my server about the change. The data I get from facebook post call is like below.
{
"object":"user",
"entry":[
{
"uid":"10152689315982483",
"id":"10152689315982483",
"time":1427362347,
"changed_fields":[
"feed"
]
}
]
}
But I did not get any call from facebook when admin of a page update its status.
I followed the below steps to get the realtime facebook update.
Subscribe user/page to get updates with access token.
graph.facebook.com//subscriptions?object=user&fields=feed&verify_token=&method=post&callback_url=htps://serverurl/realtime.php
To get the list of subscription
graph.facebook.com//subscriptions
From this call I get both user and page data.
{
"data": [
{
"object": "user",
"callback_url": "https://serverurl/realtime.php",
"fields": [
"feed"
],
"active": true
},
{
"object": "page",
"callback_url": "https://serverurl/realtime.php",
"fields": [
"feed"
],
"active": true
}
]
}
I also added the app to page-tab but still not getting the updates for page. Could anyone tell me what I am missing?
Do an http GET on
https://graph.facebook.com/v2.3/{page-id}/subscribed_apps?access_token=PAGE_ACCESS_TOKEN
If your app is not listed, you need to "install it" (this is an alternative installing the app as a page tab app). Do this by issuing a post request to the same url. Eg with curl,
curl -X POST "https://graph.facebook.com/v2.3/{page-id}/subscribed_apps?access_token=PAGE_ACCESS_TOKEN"
You don't need to supply any parameters since the id of the app you wish to install is inferred from the access token.
If /subscribed_apps already includes your app id, you may be experiencing a bug and should report it at http://developers.facebook.com/bug
The Facebook posts in which you're tagged in - using #Name - appear in your wall feed.
A friend of mine posted a link and tagged me in it:
On the Graph API documentation, when I click on my wall feed link (Ctrl + F: Profile feed), I'm able to see this post:
...
{
"id": "XXX",
"from": {
"name": "XXX",
"id": "XXX"
},
"to": {
"data": [
{
"name": "XXX",
"id": "XXX"
},
{
"name": "Christophe Maillard",
"id": "XXX"
}
]
},
"message": "The startup Guide (cc XXX, Christophe Maillard)",
"link": "http://mashable.com/2012/06/27/startup-guide-1000-users/",
"name": "How to Get to Your First 1,000 Users",
"caption": "mashable.com",
"description": "With the help of some smart marketers and entrepreneurs, we're created a clear outline for attracting your startup's first 1,000 users.",
...
}
...
The URL of this feed is https://graph.facebook.com/me/feed?access_token=XXX.
When copy/pasting the given access token - the one replaced by XXX in the URL above - within the debugger, I get something like this:
As we can see, the access token is generated by the app Test_console which used quite a lot of scopes.
Then, I go to the Graph API Explorer, I generate an access token using the Get Access Token button, and I specify all the scopes the debugger gave me, i.e. the ones the Test_console app used to generate its working access token. Finally, I access the URL me/feed by submitting the GET request. The problem: I can't see the post in question in which I'm tagged in with the explorer.
I also have my own app, and it reacts exactly like the Graph API Explorer: I can't find that post in my wall feed using the Graph API as well.
Obviously, it's possible to get the posts in which you're tagged in using the Graph API, because the Test_console app is able to generate an appropriate access token. But how can I get such an access token for my own app?
You need to grant the appropriate permissions for your app. In the graph api explorer https://developers.facebook.com/tools/explorer?method=GET&path=me switch to your app in the applications field (top right) to see what permissions that currently grants your app (by clicking the "get access token" button again). Then make sure you add in the correct one (i think it's read_stream you're after ) https://developers.facebook.com/docs/authentication/permissions/
Using GET https://graph.facebook.com/288095787880494/likes/159222380758097 returns me
{
"data": [
{
"name": "Vote For Prophet Hazrat Muhmmad (PBUH) the best man of world",
"category": "Cause",
"id": "159222380758097"
}
],
"paging": {
"next": "https://graph.facebook.com/288095787880494/likes/159222380758097?format=json&limit=5000&offset=5000&__after_id=159222380758097"
}
}
Now i want to remove this like. How do I do that? When I use HTTP Delete I get the following error:
{
"error": {
"message": "(#3) App must be on whitelist",
"type": "OAuthException"
}
}
You are not allowed to remove likes for Facebook Pages. Only for post, comment and URL's owned by your application.
To be able to do this your application must be whitelisted by Facebook which can only be done by contacting Facebook directly (and will probably require some kind of agreement and cost you money as well...)
Sounds like maybe two issues. Maybe the same. But try what I suggest in #2. Maybe facebook is spitting out a false/misleading error message.
Your app and or page is currently on the facebook naughty list. "Error code: (#3) App must be on whitelist"
You need to use a PAGE access token and not a USER access token. "It says I need to switch back to my Username in order to do that though as I mentioned earlier this link has been liked by the Page"
