I wanted to make a facebook API request that will post a message to page that I am admin of. Here i found out how can i do that but after trying it out in facebook graph api explorer with this scheme:
graph.facebook.com/page-id/feed
?message=Hello&access_token=your-access-token"
assuming I have a developer account linked to my page and publish_pages and manage_pages permissions are enabled and page-id and acces-token are replaced with my real ones. The problem is that I get a response of latest post on that website, the same as if I would write just graph.facebook.com/page-id/feed and there is no new post on my page.
I dont know if the recent facebook API update removed or modified that or if its just not possible.
trying it out in facebook graph api explorer with this scheme
graph.facebook.com/page-id/feed?message=Hello&access_token=your-access-token
You are making a GET request here - and GET is for reading data, not creating it.
Creating data requires a POST request. So you can either switch the request method from GET to POST via the dropdown there, and then click + Add parameter to add your parameters and values;
or you can add &method=post to the end of your GET request query string here - that is a way the API offers to explicitly overwrite the request method in environments, where you can only make GET requests.

I'm trying to create a test page on Facebook while developing an app. Per the instructions, I've created a test user, noted the user id and created an access token.
I'm now trying to make a POST request via curl to create a page
curl -i -X POST https://graph.facebook.com/v3.3/{user-id}/accounts?category_enum=MARKETING_AGENCY&name=Test%20Page&access_token={access-token}
However the response is an error
(#100) The parameter name is required
Seems I have supplied the name parameter though; any ideas?
EDIT
If I remove the category_enum param, the error becomes
(#283) Requires manage_pages permission to manage the object
However, I have verified the user has the manage_pages permission....
Beware of the facebook api documentation... On the surface it looks like only the name parameter is required, however after hours of experimentation with the Graph API Explorer I managed to create the test page with no less than 9 required parameters!
I am hitting a wall while developing seamless integration of a Facebook page with my bot.
Essentially I want to achieve same integration than Chatfuel or Manychat have, where being logged in with your Facebook account lets you to just choose what page you are connecting to them and you are good to go.
The problem I am facing is generating the proper token in order to bind the selected page to my app (bot). As per Facebook documentation:
When you create a subscribed_apps edge, the page-id you use in endpoint must match the page ID of the page access token used in the API call. The app that the access token is for is installed for the page.
Given the call has no other parameter than the access token, this access token has to be enough for Facebook to:
Authorize the action on the page.
Identify what app is being subscribed to the page.
This is confirmed while using the Facebook Graph API Explorer, where one selects the page and the app to bind and a proper access token is generated:
This token properly works using cURL in the terminal:
$ curl -X POST 'https://graph.facebook.com/v3.0/<MY_APP_ID_HERE>/subscribed_apps?access_token=<TOKEN_PASTED_FROM_GRAPH_API_EXPLORER>'
{"success":true}
With the Facebook Access token debugger (info icon on the left of the access token, then open in Access token tool), it is confirmed that the token knows about both the page and the app that have to be connected.
The question is, how are these page-app related token programmatically produced? I can't seem to find the proper API call in Facebook documentation and it is by all means possible, as Chatfuel and Manychat are doing this.
Thanks in advance for your support Lars Schwarz and community!
Adding some detail to Alex's answer, for it to be more complete.
When subscribing an app to a page, Facebook needs to:
Know what app you are talking about.
Know what page you are talking about.
Know that you have permissions on that page to subscribe an app.
How does Facebook know it all?
1 comes from the fact that Facebook login happens in the context of a page, actually, the Javascript code for Facebook contains your appId:
js.src = 'https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v3.0&appId=<YOUR_APP_ID_IS_HERE>&autoLogAppEvents=1';
2 Comes from the page_id in the URL used to subscribe apps to pages:
https://graph.facebook.com/v3.0/YOUR_APP_ID_HERE/subscribed_apps?access_token=YOUR_ACCESS_TOKEN_HERE
3 Comes from the access token, obtained in the context of an APP through Facebook login, that is passed as parameter in the URL used to subscribe apps to pages:
https://graph.facebook.com/v3.0/YOUR_APP_ID_HERE/subscribed_apps?access_token=YOUR_ACCESS_TOKEN_HERE
To do this, you need to put FB Login on your site/customer portal and request pages_messaging and manage_pages permissions. The person that logs in must be a Page Admin.
Once your app has been granted that permission for the page, you can generate a page access token as described here:
https://developers.facebook.com/docs/pages/access-tokens
I'm trying to download every comment on a public facebook post (it's one of those "can you do this basic algebra problem" posts - I want to see what percent of the comments get it right).
The Graph API Reference shows that I should be able to just GET graph.facebook.com/v2.5/{object-id}/comments.
I believe the object-id of this post is {user-id}_{post-id}, where post-id is the id in the url. So given this url:
https://www.facebook.com/beth.mansfield.9/posts/10207885721596563
The user-id of facebook.com/beth.mansfield.9 is 1101752663 (from findmyfbid.com), and the post-id is 10207885721596563 (from the url), which makes the object-id="1101752663_10207885721596563".
When I try graph.facebook.com/v2.5/1101752663_10207885721596563/comments in the Graph API Explorer, though, I get:
{
"data": [
]
}
What am I doing wrong? Is there another way to get the comments? There are close to a million so loading them all in the browser and scraping with javascript would be unfeasible.
That is a user profile. You can only get data of a user profile if that specific user authorized your App. In that case, you would need to authorize with the user_posts permission. Just because it is public, does not mean you can get the data - that would only work for Pages.
I'm using Facebook Graph API v2.5 to publish and delete posts from user's profiles.
I'm using Postman (Chrome extension) to test my REST calls.
Case 1) When all actually works:
- I do a POST request to "https://graph.facebook.com/v2.5/MY_USER_ID/feed", with params "access_token" and "message"
- The API returns me the created post ID, let's say "108373569531356_138530589848987"
- Then I do a DELETE request to "https://graph.facebook.com/v2.5/108373569531356_138530589848987", with params "access_token".
- My message I successfully removed from user's profile
Case 2) My issue, it does not work as expected
- I do the same POST request as previous, but I add an extra "link" parameter.
- The API returns me the created post ID.
- Then when I try to delete this post using DELETE request, the Facebook API throws me an error: "message": "(#100) This post could not be loaded"
One thing I noticed, is that first request seems to create me a Facebook "post", but the second one seems to create a "link".
I used the v2.3 API get/post_id to compare both posts, they are pretty much different.
So, why can't I delete a "link" element, the Facebook documentation does not tell anything about it.
Many thanks !
Maybe you were suffering a bug (https://developers.facebook.com/bugs/1671530079772375/) which is fixed now.
If you published a post with a link through an app being in development mode, this post wasn't credited to your app [bug] so, if you tried to delete it, you couldn't because Facebook only allows to delete posts published by your app.
This is confusing. So just to clarify:
REQ #1: To fetch basic stats for a URL, you send GET request to:
http://graph.facebook.com/?ids=http://some.com
(alternatively, FQL can be used to fetch stats for a URL, but that doesn't return the OpenGraph Object)
REQ #2: To fetch comments for a URL, you do a GET:
http://graph.facebook.com/comments/?ids=http://some.com
REQ #3: To fetch likes for a URL, you GET:
http://graph.facebook.com/likes/?ids=http://some.com
But how do you comment on / like a URL programmatically?
I guess, likes can be created using Open Graph API, right?
https://graph.facebook.com/me/og.likes?object=1234
where 1234 is the OpenGraph Object ID of an article (as returned by REQ #1).
But this requires an approval process, the like action has to be approved by Facebook.
Is there a better way to do this? Can I use for example the Graph API for all these things?
My goal:
Currently I'm using the Facebook like button and comments plugin to create likes and comments. But these use the JS SDK, which is huge, and they generate a lot of external requests. I wanna get rid of them and just send an AJAX request to my server, which would then asynchronously talk to Facebook, and it would post the Like / Comment.
Is this possible?
Thanks in advance!
I read through the Facebook docs briefly and I don't believe you can do this other than the way you indicated with authenticating.
You should also take a look at this thread: 'Like' a page using Facebook Graph API
You would need to authorize every single user before he would be able to like something, and you would need to go through a review process on Facebook. And i am pretty sure you would not get the required permissions approved just because you want to get rid of the JavaScript SDK overhead, to be honest.
The Social Plugins are asynchronously, so the overhead for downloading the SDK is irrelevant as it happens in the background and it is non-blocking.
I have an idea, to do this. You can use long term access token, Once you login you receive short term token. After receiving short term token you need to request your long term access token. Save that token in DB or file.
Then you can use Graph Api, to make requests. This will eliminate the need for access requirement every time you request api.
Just use access token you saved before.
Refer this documentation from Facebook for further clarity.

Happy Coding!
