I'm making a Facebook canvas application, and I want give some of the objects there "Facebook presence" - I want to allow users to comment on them and to like and share them via Facebook.
I understand I need to do it via OpenGraph. So I created an object type on my OpenGraph and named it item. I've tried to create an instance of item with the following POST request:
url:
https://graph.facebook.com/https://graph.facebook.com/me/objects/ilender_local-test:item
body:
method=POST&object=%7B%22type%22%3A%22%5C%22ilender_local-test%3Aitem%5C%22%22%2C%22title%22%3A%22My+First+Item%22%7D&access_token=...
The access_token, ofcourse, is the access token for my app.
Now, the result I get is a simple JSON false - no error message - but I assume I failed since when I succeed in creating an object on Facebook I usually get the id of the newly created object.
What am I doing wrong?
My stupidity knows no end. https://graph.facebook.com/https://graph.facebook.com? What was I thinking...

I'm creating a custom module in Drupal, that for part of its functionality must fetch posts from a business page. So for simplicity, I'm using fbapp module as a dependency (drupal.org/project/fbapp), so that I can use it's authentication and request functions (fbapp_app_authenticate() and fbapp_graph_request()) without having to worry about the constant facebook graph updates making my own code obsolete.
I've created a facebook app, so authentication should be app token, using appid and app secret. This seems fine and I'm getting back access_token. However, when I try to read posts from a publicly available page (the clients), I get the response:
"Unsupported get request. Please read the Graph API documentation at https:\/\/developers.facebook.com\/docs\/graph-api"
Here's the queries and responses my code produces:
graph.facebook.com/oauth/access_token?client_id=<redacted>&client_secret=<redacted>&grant_type=client_credentials
array(1) {
["access_token"]=>
string(43) "<redacted>|<redacted>"
}
graph.facebook.com/<page_id>/posts?access_token=<redacted>|<redacted>"
string(183) "{"error":{"message":"Unsupported get request. Please read the Graph API documentation at https:\/\/developers.facebook.com\/docs\/graph-api","type":"GraphMethodException","code":100}}"
Can anyone verify a correct way to query a Facebook page programmatically, perhaps there's a setting in the page I'm querying that I need to set (although I can't find anything)?
If page restrictions apply, the page's feed can only be retrieved with an user access token as far as I know (because FB needs to evaluate the visibility criteria, and setting your app to the same restrictions doesn't help here):
See
https://developers.facebook.com/docs/graph-api/reference/v2.4/page/feed#readperms
It looks like everything you have done is correct. The response you got can be (i am not sure) because you got your clients pageid wrong.
Given the URL of a public Facebook post, how can one find the post object in the FB Graph API? (secondarily, why are so many user feeds empty or nearly empty when accessed through the API?)
We would like to be able to comment on or like a post via the v2.x
Graph API, given the post's URL. Doing so requires the post's object
ID, which we can make some educated guesses about, but accessing
the actual object through the API has proven unreliable (works for some posts but
not others).
v2 of the API introduced app-scoped user IDs, and post IDs generally seem
to be of the form {app-scoped user id}_{unique post id}. Here are the
details of some attempts to find posts in the API with various combinations of
these IDs (global user id, app-scoped user id, and post id).
Starting with a simple example: https://www.facebook.com/evan.prodromou/posts/10153023417510505. Key characteristics are that it's public, it's not a share of another post, and most importantly it has no photo(s), which add extra ids and URLs for the individual photo(s) and photo set. Evan's profile is also public, i.e. https://www.facebook.com/evan.prodromou doesn't show the generic This content is currently unavailable
Trying the bare post id from that URL, /v1.0/10153023417510505 and /v2.2/10153023417510505 both give the Unsupported get request (code 100) error.
Evan's global user id is 525575504. Attaching that as a prefix, /v1.0/525575504_10153023417510505 and /v2.2/525575504_10153023417510505 still both give the same Unsupported get request error.
Same error using his app-scoped user id instead, /v2.2/10152350676805505_10153023417510505.
OK let's try the other direction. We'll page through the user's feed until we find the post in question. It feels like this is more the expected use case for the API...
Both the global /v2.2/525575504/posts and app-scoped /v2.2/10152350676805505/posts return nothing, but /v1.0/525575504/posts returns two recent posts, this like and this post. Not sure why only those two, even though has plenty of other recent public posts. The like is fetchable via its id field in both api versions, i.e. /v1.0/525575504_10153045879215505 and /v2.2/10152350676805505_10153045879215505, but both API versions return the Unsupported get request error when fetching the post via its id field, e.g. /v1.0/525575504_351575675029953 and /v2.2/10152350676805505_351575675029953
Trying another public post, this one with pictures: https://www.facebook.com/andigalpern/posts/678121182314631 . /v1.0/100003502653187_678121182314631, /v2.2/100003502653187_678121182314631, and /v2.2/499657186827699_678121182314631 all error.
/v1.0/100003502653187/posts only includes one post, a like, and /v2.2/100003502653187/posts is empty.
For reference, here is the GitHub issue where we have been tracking this problem.
Basically you would need read_stream for this (which your app will not get granted). And yes, even though the post is public, you still need read_stream to be able to get read access to all kinds of posts.
You can easily play around with this in Graph API Explorer. First give your app read_stream permission to get ids of items in your feed – that will give you ids of the “form app-scoped user id underscore post id”. Then remove read_stream (by clicking “Get Access Token” again and using the “Clear” button), and try several of the user_* permissions – and you will see that for most of your posts, even the public ones, you will still only get “Unsupported get request”, which just means you are not allowed to read that object.
F.e., I have a public post where shared a video post from another page on my timeline, the type is video and status_type is shared_story, but neither user_status nor user_videos allow me to read this post – only when I grant read_stream again, my app can read that post. Same with another public post of type status and status_type mobile_status_update – readable with read_stream, not with any of the user_* permissions.
In short: What you want to achieve is not possible any more with API v2 and the restriction that read_stream will only be granted to apps on platforms where no official FB client exists.
A one proposition is to make api calls to write facebook posts since those return valid post_id that you could use
Second,
When you try https://developers.facebook.com/tools/explorer/256884317673197/?method=GET&path=525575504%2Fposts&version=v2.0&
You can see that his posts ID's are not starting with his public id as you wrote 525575504_*
but they still put unsupported get request
https://developers.facebook.com/tools/explorer/256884317673197/?method=GET&path=10152853212485505_351575675029953&version=v2.0
Third since above doesnt work are those posts public for sure?
I'm trying to post custom story with applink. I have defined action type complete and an object step - so user can "complete a step" inside app. Then I defined one step using Object Browser. How can I add applink via Object Browser?
There is a field al:android, which I assume needs to be filled with data. There is a hint stating that I should put there JSON object or array. So I did.
Tried with:
{"package":"com.example.myapp","class":"com.example.myapp.MainActivity","app_name":"My Example App"}
I've got error:
Is there a way to make this work?
You can use Facebook Mobile Hosting API to create App Link objects. Here is documentation: https://developers.facebook.com/docs/applinks/hosting-api
Should get in return something like this: {"id":"643402985734299"}, this is the ID of hosted applink - try with it.
I'm building a website for a franchise organization that has many franchisees. Each franchisee claims it's own part of the site represented within the path - for example the main site url is bigcompany.com and the the Atlanta store url will be bigcompany.com/atlanta. When trying to place the like button on the page it works when given the main organization's app id, but shows nothing when given the franchise app id.
I've tried using the url debugger on facebook (https://developers.facebook.com/tools/debug/) and the error that I receive is
Object Invalid Value: Object at URL 'http://bigcompany.com/atlanta' of `type 'website' is invalid because the given value '12345678901' for property 'fb:admins' could not be parsed as type 'fbid'.`
I'm not sure what that means and haven't found a suitable answer so far.
Why is the like button not showing? Thanks
tl;dr: No, there isn't a way.
Calling publish_action using the JS SDK is actually pretty straightforward. However (from the little info I gleaned from reading the documentation), there's no way for me to query facebook to have it return the action instance ID for an object that I have already published... is there?
Example:
User A loads the page, and the page sends an FB.api call to /me/news.reads, which returns an action instance ID.
User A reloads the page, and the page again sends an FB.api call to /me/news.reads, but this time, the Graph API returns:
{
error: {
code: 3501,
message: 'blahblahblah... already associated... blah blah'
type: 'OAuthException'
}
}
Pretty standard stuff, and expected, since I turned off the ability to publish the same URL multiple times.
Now then, is there any way for me to retrieve a previously published action instance ID from the Graph API by passing in the URL, or is it up to me to handle the returned action instance ID (from the original publication attempt) and save it to a database? I was hoping I wouldn't have to do that...
No, there is no way to retrieve instances of published actions other than:
Accessing action by id:
http://graph.facebook.com/ACTION_ID
Accessing all instances published by specific user:
http://graph.facebook.com/USER_ID/NAMESPACE:ACTION (NAMESPACE:ACTION may be replaces by the name of one of built-in actions like news.reads, music.listend, etc.
If you want to access details of published actions connected/referencing specific object you'll need to save that data on your end for later usage.
