I'm trying to support the ability to post to to a Facebook page as both the user and as the page itself.
As the user, I'm calling the following:
POST https://graph.facebook.com/<page_id>/feed
message=test&access_token=<user_access_token>&format=json
As the page, I'm invoking the same call, except the access_token is the token returned for that page by me/accounts.
In both cases, the post is made by the page.
Is there a way using the API to post as my user to a page I administer?
See 'Actor name will always match the access token' on the Facebook Roadmap - this is a migration to resolve the inconsistency you're encountering here.
Using the User access token of a Page admin can still cause the post to be made as the page depending on what that user has selected in the page management settings on facebook.com - there's an option to 'Always post as even when logged in as '
Enabling that migration causes the post to always be from the owner of the access token (i.e page access token posts as the page, user access token posts as the user)

I am pulling my hair out trying to understand what Facebook wants me to do to post to a FaceBook Page as a System User that has Admin and Page Privileges to and Owned by our business (We have Facebook Business Manager).
In a nut shell all I want to do is make this call:
https://graph.facebook.com/v2.5/${MyPageID}/feed
What I don't get is the access_token part.
I can generate access tokes for Apps, for Pages but all result in 403 returned from FaceBook. I have gone as far and checking every box available on the generate access token popup on the graph api and still I get 403 "Forbidden" so I am detailing the little I understand of the insanity that is FaceBook Auth in the hope that someone can explain where I am going wrong.
1) To Post as a System User to a Page I have to Create a FB App (I Would prefer just to post direct to the pages and skip the App part, My System User has Admin Access on All pages)
2) To Access the App I need an App Token.
3) To Create an App token I need a User Token.
4) To Create a user token I need to log in to Facebook and have all sorts of permissions on the App. (I can't log in as the System User! FB asks me to login as myself. I am not sure if this breaks the Auth Token generated?)
5) Then there are all sorts of swapping tokens to get a Permanent App token, Another point of potential failure!
6) IF the stars and moon align and you stand on your head the permanent App key can be passed to the above call as the access_token
I don't understand how to link the Pages I want to post to with the App created. Do I have to have 1 App for Each Page?
I have got one page to work, We initially used that App to Auth against the Instant Article Graph API:
https://graph.facebook.com/v2.5/${MyPageID}/instant_articles
I could not use the above token for the /feed url, I had to generate a new token with extra publish permissions and the page published with no problems, however when I change the ${MyPageID} to another page using the same access_token I get the 403.
I tried Creating a new App, I have no clue how they link to a specific page So the App to me seems sort of redundant.
Any help with what I am doing wrong or how I can go about simply posting to various FB Pages with a System User using the /feed api ?
The calls are made form a Spring Boot Java APP using HTTP Posts.
How to get a System User Auth and Page Auth:
1) Generate a User Token for an App (Button above the System User):
https://business.facebook.com/settings/system-users/${System User ID}?business_id=${your_business_manager_id}
System user has Page Admin on each page you need to post to.
App is just an FB app, not sure what it does other that it is a grouping I generate a token against.
I chose: (manage_pages, publish_pages, publish_actions, pages_manage_instant_articles, pages_show_list)
2) Check your access token:
https://developers.facebook.com/tools/debug/accesstoken/?access_token=${The access token you got from the step above}&version=v2.12
This will provide you with the App ID the Token is for and how long it lasts (we need a Permanent token)
3) Using Graph API Explorer gets the Accounts this token has access to:
https://developers.facebook.com/tools/explorer/${Your FB APP ID}/?method=GET&path=me%2Faccounts&version=v2.12
4) Using the output above find Page Auth for each page you wan to publish to
5) Post to each page in turn:
https://graph.facebook.com/v2.5/${MyPageID}/feed
I've been reading documentation and Stack Overflow link all morning, but I'm just not understanding the correct process to authorize a web server to post to a Facebook page wall.
What I'm not clear on is why I have to post to Facebook as a Facebook User, using an access_token, meaning that this user has to log into Facebook manually to authorize my app.
I'm not trying to authorize a User, nor any of my visitors to do anything with their accounts, so I don't need any permissions from them. Instead, I'm trying to authorize my Web Server to post updates to its wall as a specific Page.
Why do I have to use a user access_token to do this? I'm not attempting to impersonate the user, I'm trying to post to the page as the page...
Is it possible to authorize a user and get their access token without having to create a login page on the Web Server? I don't want to have to require the user to login to make this work, I thought that was the point of having an app ID and Secret?
I guess my question is this: Is it not possible to allow a web server to post to a Facebook page wall as that page, without having to present a login dialog to a specific user? If it is possible, what is the correct workflow to set this up?
In order to post to a Page as a Page, you have to use a Page Access Token. You get that with a User Access Token, and you can extend it so it will stay valid forever.
Steps:
Request a User Access Token with the manage_pages permission (valid for up to 2 hours)
Extend the User Access Token (valid for up to 60 days)
Get the Extended Page Access Token for your Page with the User Session
Store and User The Page Access Token in the publish call
It may sound a bit complicated, but there are many tutorials for this and you don´t actually need to program it, you can just use the Graph API Explorer.
Here are some Links about the Access Tokens:
https://developers.facebook.com/docs/facebook-login/access-tokens/
http://www.devils-heaven.com/facebook-access-tokens/ (see "Extended Page Access Token" for a step by step tutorial)
Let's say I've create a facebook page named MyPage.
When I am using a web interface of FB, I can either post on that wall as the user I am logged in as (personal user) or as a page instance, MyPage user.
Is it possible, via any of the available API's, to post on a facebook page as that page's user programmtically from my desktop application code?
To post on facebook page as that page, you need an page access token of that page.
To get the page access token, you need-
permission: manage_pages.
API call: /{page-id}?fields=access token
(If you are not aware, you can test the graph api calls from: Graph API Explorer)
In the posting code, just add a parameter: access_token and give it the page access token. That's it.
PS if you wish to extend this token, that'll never expire, you can get the login from here: What are the Steps to getting a Long Lasting Token For Posting To a Facebook Fan Page from a Server
I have tried just about everything at this point, but I cannot get a like or a comment to show up as my user, if I am logged in as the admin of a page. My app allows people to manage their pages, but even if I pass my user's access token back instead of my page's access token, it still performs the action as though it were the page. This is also true of the Graph API explorer. I've logged into Facebook, flipped over to posting as user, then ran the graph API on the post in question, generating a fresh access token from there and the post STILL showed up as the page! Is this broken? Should I submit this bug to FB?
Yes I have all the required permissions, yes I'm verifying that I'm using the user access token and not the page access token... the Facebook API returns true every time, however, even through the Graph API explorer and not through my app.
http://developers.facebook.com/bugs/408406055876958
This is a known facebook bug, opened in July, with no timetable for fixing it.
Is it possible to somehow get an access token to use the facebook api like a user that clicked "use facebook as "?
What I'm trying to do is to allow my website to post messages to the facebook page's wall. I already have an app which I use to allow my users to login with their FB account. However, I'd prefer not to require a page admin to authorize full manage_pages to my app. I already added the app to my FB page, but there are no options to give that app some permissions for my page.
Of course it's possible.
In the official documentation page about Permissions it's written:
Page access_token
An access_token used to manage a page. This is used
when you want to perform an operation acting as a Page. This access
token is retrieved by issuing an HTTP GET to /USER_ID/accounts or to
/PAGE_ID?fields=access_token with the manage_pages permission. Getting
/USER_ID/accounts will return a list of Pages (including app profile
pages) to which the user has administrative access in addition to an
access_token for each Page. Alternatively, you can get a page access
token for a single, specific, page by issuing an HTTP GET to
/PAGE_ID?fields=access_token with the manage_pages permission (you
must ask for the access_token field specifically via the fields=
parameter). See the documentation for the Page object for more
information. NOTE: After November 1, 2011, manage_pages permission
will be required for all access to a user's pages via this connection,
i.e. for both reading the user's pages and also retrieving
access_tokens for those pages. See the documentation for the User
object for more information.
