I have an application "Tipsters Corner" and a page ,also called Tipsters Corner.
I want to post on that page.I managed to do this using the token obtained from the graph explorer.
But I do not understand the difference between all the tokens.
I have a dropdown ,with the following options :
Graph Explorer
Tipsters Corner Application
I click Get Token.I get a token,a different one depending on what I selected in the dropdown.
I can post to my facebook application using any of the tokens.What is the difference between them.
Also,if I enter me/accounts I see my page/pages and another access token over there.What is that ?
Is that the token for the user?
The tokens that you retrieve from the Graph Explorer are short duration User Access Tokens which are generated different for different applications and different permissions.
The Access tokens that you retrieve when navigating to /me/accounts end point are the Page Access tokens for various Pages you administer or are associated with. These access tokens do expire, but if retrieved from the /me/accounts end point using long lived access token these do not expire (documented here) and can impersonate things done by application as the Page itself.
You may further like to give the documentation about access token a read.

As the title suggests im wondering how i could obtain a never expiring facebook user access token. Which i would need to create a page access token at a later date. I tried using their graph explorer tool but i could only make it go up to 2 months of expiry date and for my use case that wouldnt be ideal.
To shortly explain my use case, on our website im trying to implement a facebook sharing system where each user could share what they wanted i.e posts on their facebook page (we are not using facebook login and the user would just give acces from their own dev tool panel if thats the correct approach). I got this to work BUT only with a acces token that would expire in 2-3months. So a user having to re-authenicate with our service every 2-3 months isnt ideal and wouldnt really work for us. So is there a way i can refresh that token programtically or does the user have to give a new user access token every couple of months.
I have tried following this answer but with no luck Long Lived access token Facebook Page and many similar answers to this. There is also a suggestion that you should contact facebook if you want a never expiring access token which this user suggested Generate permanent access token Facebook API.
Now im wondering if it even is possible do that in 2021 and if there is anything i missed in regards how to generate said tokens or refresh them.
EDIT:
I used the following requests to get the extended access token.
https://graph.facebook.com/oauth/access_token?client_id=<your FB App ID >&client_secret=<your FB App secret>&grant_type=fb_exchange_token&fb_exchange_token=<your short-lived access token>
After i got the token i used
https://graph.facebook.com/me/accounts?access_token=<your long-lived access token>
to get the extended access token.
To get page access token that never expires, take the following steps:
Get user token
Make this token long-lived, e.g. by clicking "Extend access token" at the bottom of the page: https://developers.facebook.com/tools/debug/accesstoken/
Then, use this token to get page access token.
In Access Token Debugger the token will be marked as "Expires: never"
I have built a platform for my local young professionals organization with a PHP backend using Laravel. One of the newest initiatives I am wanting to take on is the integration of our marketing insights and for the board to take a quick look at our marketing efforts without needing to be directly in the software, such as our Piwik setup and FB page insights.
I have pulled the Open Graph/FB SDK and have configured some basic APIs to use in the software. I am wanting to make it so board members without admin access on the FB page can still see the insights. Is it possible to use an app access token to grab the insights? Do all of the board members viewing the PHP page need to be logged into FB with admin access to the page?
This is possible if you use a long-lived (eternal) Page Access Token.First, you'd have to get a User Access Token, for example via the Graph Explorer (https://developers.facebook.com/tools/explorer), with manage_pages and read_insights permissions.
Then, you need to exchange the returned short-lived User Access Token with a long-lived one. Next, request /me/accounts with the long-lived User Access Token and fetch the eternal Page Access Token from the result. Store it your application for further use.
You can check the Access Token with

I'm building an application for an event so they can directly post their news messages on facebook. I'm trying to use de php SDK V4 for this but there are some parts of the login process I don't understand (still couldn't find a solution after searching for several hours).
My Problem is in the login process. First you have to specify which applicaton you are and give your application secret. Than you have to login to facebook with an account.
But which account should I use for that? The one of their event? Mine?
(I'm an admin of the events page) (this means that all messages will
be posted from mine account while i'm not the poster...sounds pretty
weird..)
Which method should I use to login into facebook? There is a veriaty of methonds like the FacebookRedirectLoginHelper(), the FacebookCanvasLoginHelper() or the Javascript one. However as far is I understand all these helpers for your users to login to their facebook accounts and that's not what I want.
During my search I found some an example of someone who is making a similar system (Facebook Graph API PHP SDK v4 - Post on Page). He/She uses the folowing piece of code for getting a facebook session:
FacebookSession::setDefaultApplication('{APP ID}','{APP SECRET}');
$session = new FacebookSession('{Page Access Token}');
This suggests that you don't need to login into facebook by user but only need a Page Acces Token. However if I understand it correctly (correct me if I'm wrong), to get a Page Acces Token, you first need an User Acces Token (https://developers.facebook.com/docs/facebook-login/access-tokens/#pagetokens). To get an User Acces Token you should be logged in, and than we're back to question 1 and 2 in the beginning of my story.
Or can I just get a Page Acces Token using the following api request (according to https://developers.facebook.com/docs/facebook-login/access-tokens/#pagetokens)
GET /{user-id}/accounts
Using a random user-id as long as the page admin gave this user permission to generate such a token (so the user related to "user-id" shouldn't be logged in while retrieving the Page Acces Token?) .
Sounds like you'll need to use the following flow:
Have the page admin log in with their Facebook account. Make sure to request the manage_pages extended permission. This will give you access to the pages they admin.
Once they grant access to your app, you'll get a short lived user access token. Exchange it for a long lived user access token.
Get the list of the user's pages with /me/accounts. Each page will have an access_token field returned with it. These are all page access tokens. We want to use a long lived user access token to get this list so that all the page access tokens returned will not have an expiration date. They live forever! :)
Use the page access token to post to the wall of the page if you want to post as that page. Use the user access token to post to the wall of the page if you want to post as that user.
And the Facebook Query Builder might make this whole process a lot easier. :)
Hope that helps!
Firstly I am aware that there are a million questions similar to this, but they are all either out of date (Facebook has changed and the instructions no longer work) or don't explain how to do specifically what I am asking.
I'm trying to register an app on Facebook so that I can autopost to the company Facebook page, of which I am an admin.
I'm trying to do this via PHP, with which I have considerable experience (PHP, not Facebook API.)
So far I have registered as a Facebook developer, made a Facebook app, got the appID and secret word, and downloaded the facebook-php-sdk from Github. I have attempted to follow a couple of tutorials but the Facebook developer/app pages have all changed and so the intructions are now invalid.
All I want to do is to be able to post automatically to my page's wall from the server via PHP, as if I posted the status update myself as the page admin. I don't understand how or why this is so difficult.
The Facebook app page has a million settings that I've never heard of and don't seem to be related, then there is no information that gives any direction to do what I want to do.
This is about as far as I've got and I've hit a wall. No idea what to do next. Facebook keeps asking me "Select how your app integrates with Facebook" but their options don't appear to include what I want, which is just to post on my own page. I don't appear to actually be able to use the app yet, as there are various settings its insisting on, like "Canvas URL", which I do not understand, etc. and then I obviously need to set permissions, yet I see no way to do this either.
What do I do?
Setting up an app
You are going to need to authenticate the user who has at least content creator rights on your page. So you need to choose 'Website with Facebook Login' and enter your website url.
You'll also have to enter the domain (website url without protocol)
Keep it in sandbox mode while you test it you can edit that later.
You don't really have to worry about other settings as the permissions to ask can be added directly in your php code.
"Online" Access
To logging and post directly to facebook you'll need to retreive an access token
Getting an access token
Here is a basic run down:
Get user to login and allow app with appropriate permissions (manage_pages, publish_stream) if he hasn't
Retreive user access token
Query /me/accounts with user access token to get the page id & access token
Then all you have to do is make your API call with id & access token to post on facebook
"Offline" Access
In order to post without having to logging (usefull if you aren't the only one posting) you need a permanent extended token. So you basically should have a separate script that you'll run once to retrieve that extended token and store it.
Getting an extended access token
To be able to post without the user being logged in you need a permanent access token for your page.
Here is a basic run down:
Get user to allow app with appropriate permissions (manage_pages, publish_stream)
Retreive user access token
Change user access token for extended user access token
Here is how I do this step (you could also use curl)
$token_url = "https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUT_APP_SECRET&grant_type=fb_exchange_token&fb_exchange_token=OLD_TOKEN";
$accessToken = #file_get_contents($token_url);
Then
Query /me/accounts with user extended access token to get the page
Change page access token for extended access token (same code as
above)
(The last step shouldn't be necessary according to the doc as you should get an extended page token when you query /me/accounts with an extended user token but in my case it didn't work)
And you get a permanent access token that only expires if the user changes password or disallows the app. All you have to do is store it with the page's id and retreive it wherever you need an API call to post to facebook.
The php sdk is pretty well documented so you shouldn't run into any problem a google search can't fix. Look for post september 2012 threads the flow hasn't changed since neither did the php sdk much.
I'm using the PHP SDK of Facebook to retrieve all sorts of information.
If you don't know, facebook keeps a temporary link for every video hosted on it and that link becomes inactive after a few days.
Therefor, I query FB using PHP with a vid to get it's url.
The problem is that I have to do that action even if a current user that's viewing my page isn't connected to my app.
Do you have any creative solution for me to query FB with a vid (video ID) even if the current user that's browsing my website isn't connected to my app?
(I could use an existing user token but now I have to control which tokens are alive and so on...)
Thanks!
If you're only going to query publicly accessible videos use your App Access token. Unlike an access token you obtain from a user, your app access token will not expire unless you reset your secret key. Take a look at this: https://developers.facebook.com/docs/opengraph/howtos/publishing-with-app-token/
