I'm using a facebook extension in TYPO3 to pull out the facebook posts of a page. Therefor I need the accesstoken.
I googled around and found that I need a facebook app and I need to be administrator of the page.
Then I heard that I need to connet the app with the site, but how can I do this?
I also tried to get accesstoken:
https://graph.facebook.com/oauth/access_token?client_id=APP_ID&client_secret=APP_SECRET&grant_type=client_credentials
And then performing:
https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token& client_id={app-id}&client_secret={app-secret}&fb_exchange_token={short-lived-token}
... with this token but it says No user access token specified
Can someone help me step by step how to get the long lived token?
As you just want to pull, you really don't need a page access token. Until and unless you have a demographic or other restriction over your page. All the pages are Public and data over them can be easily accessed by using the App Access Token which is simply put
Your_App_ID|Your_App_Secret
first u need to get an API key from facebook, so here are the steps--->
http://www.shoutmeloud.com/how-to-acquire-your-facebook-api-key.html
& then u can access facebook API, these are docs provided by the facebook to use that API--->
https://developers.facebook.com/docs/guides/web/
This was my implementation (PHP):
$newposts = json_decode(file_get_contents("https://graph.facebook.com/YOURFBPAGE/feed&access_token=YOURAPPID|YOURAPPSECRET"));
Since I was only using this to make simple pull request of my feed posts this is the best way to do it. You don't have to deal with expiring access tokens. Just create your facebook App and get the ID and secret.

I have a CMS application which needs a little component that allows an editor to select a facebook page post to display.
I've been going around facebook API and I don't fully understand what is the proper way of doing it.
This would be a server call, I would prefer not to have an access token because I am not making the request on behalf of any user.
I've tried using access_token=app_id|app_secret, but apparently that request requires an user session. So I went to the graph explorer and copied my access token. That worked fine initially but then I learned that they expire. I could get a long live token, but apparently those also expire eventually.
So, what is the best way of doing this? I think that using someones facebook access token for this is risky. The token could be revoked at any point breaking the feature in production. Can I achieve this without an user access_token? if I cant, how is this token normally managed?
Update:
Well actually the app_id|app_secret works, just not in every case. I created several pages for testing purposes and it doesnt work in any of them. Then I tried accessing a post from some brand pages (unrelated to my project) and they work ok. So my problem is configuring the page.
When I tried to access the post using app_id|app_secret I get:
(#100) Requires user session
Posts are public in all cases
I already tried to assign a vanity url to the page, no change
I think it's not possible to use just an App Access Token to get the Page Posts. Unfortunately the docs are not very clear on this IMHO:
https://developers.facebook.com/docs/graph-api/reference/v2.2/page/feed/#readperms
An access token is required to view publicly shared posts.
A user access token is required to retrieve posts visible to that person.
A page access token is required to retrieve any other posts.
I have a Node.js server running a social network site and I also have a facebook page for that site. For certain actions performed by users on my site, I want to post details on the facebook page of my app.
I referred to Thuzi facebook node sdk here on how to post to facebook wall. However, it requires app id, app secret and a temporary access token. App id and app secret are constant so I can put them somewhere in my config file and use from there. But how do I get the access token without any interaction from front-end ? All posts will be published by our app only and that too on our own page. I just want this to be triggered by the end user's actions. Any help ?
I am using Sails.js framework btw.
You would need to use an Extended Page Token for that, you only need to create it once and it will stay valid forever. And you will post "as Page" with a Page Token. How to get an Extended Page Token:
Create an App
Use the Graph API Explorer to generate a User Access Token (by authorizing the App with the manage_pages and publish_actions permission)
Extend the User Access Token (valid for 60 days)
Request an Extended Page Token by calling /me/accounts
Store that Extended Page Token on your server and use it for posting on the Page wall.
Here are some additional resources, explaining everything in detail:
https://developers.facebook.com/docs/facebook-login/access-tokens/
https://developers.facebook.com/docs/graph-api/reference/v2.1/page/feed
http://www.devils-heaven.com/facebook-access-tokens/
http://www.devils-heaven.com/extended-page-access-tokens-curl/
I am also digging more in to this nowdays As I am working on a node module for this.
Till now I got to know that we can create a temporary access_token and we can than extend that token upto max 60 days.
For this after getting temporary token you need to make a call to this url to get a access token with 60 days validity.

I'm fairly new to facebook development and I still get confused about the oAuth thing.
A client of mine asked me to show the latest posts, links and statuses of his facebook page to his website.
On the a php page on his website I'm creating a url
"https://graph.facebook.com/".$clientFacebookPage."/posts?limit=1&access_token= xxx
In order to json decode it and display the info I want, but I don't know how to get an access token. I generated an access token with the graph explorer that is tied to my name as a facebook developer but that expires in 2 hours.
There are many thing that confuse me already and I hope you can point me towards a solution
I've read the documentation but everything revolves around users getting logged on your app and you app posting. So my questions are:
Do I need to create an app to do a curl (requiring special permissions) using the http://graph.facebook/xxxx url?
If so, does the adming of the facebook page need to authorize with the app?
What do I need to do next? I can create a web page using the app id and secret. Does that mean that I can retrieve the info of the facebook page? How?
I know that the page needs an auth token to curl the http://graph.facebook/xxxx page and retrieve the data needed. Where can I generate it? Does the webpage need to generate it, or do I have (as the app developer) acquire the token and write it to my php code?
If I log out of the facebook, will the program/webpage stop functioning?
I hope I didn't confuse you.
Thank you.
The basic process for obtaining an access token for a Page is as follows:
1. Get a user access token for a User who is an admin of the Page
2. Using this User token, request graph.facebook.com/me/accounts and look for the correct Page ID in the list returned.
3. Grab the associated Page token from that ID
4. Use it to do Page stuff.
There is a newly launched Facebook docs guide which shows you how to obtain one of these access tokens in a step-by-step fashion:
https://developers.facebook.com/docs/howtos/login/login-as-page/
Hopefully that guide should help you.
I will also answer your questions in order:
Yes, you will need an app in order to generate access tokens to make API queries
Yes
This is in the guide linked above (start at the Getting Started if you need to create a way to get a User Access Token also)
Again, see the guide above
Yes, but you should follow the steps in this guide to generate a long-lived access token. Once you do that, any Page token you retrieve will last forever.
I'd like to show my facebook wall posts on my website.
So i don't want to authenticate users with a dialog, to grant them some rights, i just want to show him my wall with comments (no ability to add comment just read only access).
As i know there isn't unexpired tokens now so is it possible to access just my data without requesting token every time it expires?
I'm using asp.net mvc but i think this sultion doesn't depend at platform at all.
You should:
Make your Facebook Posts public
Call the API endpoint: https://graph.facebook.com/{your_id}/feed?access_token={app_access_token} with your user_id and valid application access_token
Show the results on your website.
The App Access Token doesn't expire so you won't have a problem. As long as the posts are public, the API will be able to pick them up. In theory, your posts should be public anyway so anonymous users can see this.
This also gives you the ability to share stuff privately and not have it show up on your website.
I am trying to get the post of a Facebook Page throw iOS API and I can't do it without login before (without access token). Is there any kind of solution to make this? Does anyone know it?
The App report me the follow error:
An access token is required to request this resource.
UPDATE
I generate one access token with this structure: APPID|APPSECRET and give it an expiration date. With this, I can access to the public data of my Page :)
Thanks,
David
Graph API Documentation seys:
posts [..] any valid access_token or user access_token
More informations you can find there http://developers.facebook.com/docs/reference/api/page/
Here is live example http://developers.facebook.com/tools/explorer/?method=GET&path=19292868552%2Fposts
+1 well... facebook data is all about "user", therefore you always need valid access_token
there are few exceptions though,
for example, you can display user profile picture without token,
see example;
https://graph.facebook.com/100001789213579/picture?type=large
