I am using facebook C# SDK 5.3.2 for desktop application. I created an application on the facebook to get AppId. I can get accsess token using this appid. And i can also post my facebook wall. But i also want to post my friends's wall. How can i do that without using AppId? My senerio is add all friends to app getting accsess token and post mesages to their walls using this tokens. Is that possible? How can do that?
You have to get authentication from users in order to retrieve an access token that will work for them. You have to use your APP_ID in order to authenticate your application with a user.

I want to play around with pynder but in order to do so, I need a facebook access token.
I've googled around, and made a facebook developer profile. I have an app Id and app secret. How can I go about getting what I need to create a session in pynder?
Facebook is using OAUTH2. Basicly you have to redirect the user to facebook. He authorizes your app. Facebook redirects back to your site with a &code= Parameter.
You call an facebook endpoint an exchange the code to an access_token.
https://developers.facebook.com/docs/facebook-login/access-tokens
You can grab an access token out of https://developers.facebook.com/tools/explorer/
You should be able to change to your app and generate a token.
I am trying to access a public FB community page and display the images on web page, example-http://www.codeofaninja.com/2011/06/display-facebook-photos-to-your-website.html
My site is being developed in java, so I am looking for a core java solution to do something like this.
My site does not prompt for the user to login via Facebook or authenticate. I am simply trying to display all the images from my own album on my website.
I have created an FB app, and then created a community page on which I have my pictures.
I am struggling to I authenticate from the backend code of my with my app or page. My app has user_photos permission and the App Type (Apps->Your APP->Advanced->App type) is Web.
Here are the things I tried using graph API:
1) Get access token
https://graph.facebook.com/oauth/access_token?client_id=ABC&client_secret=XYZ&grant_type=client_credentials
2) Then use access token to get access to the page and its albums, but the above gives me app access_token. As mentioned on Graph API documentation for Page it requires a page acess_token, but I am not understanding how do I get the page_access_token via an app access_token with a backend application.
After Page access token is retrieved I can use the following call to retrieve all photos.
https://graph.facebook.com/PAGE_ID/photos?access_token=<page_access_token>
You can make the following Graph API call To get the page access tokens for all the Pages a particular user admin.
https://graph.facebook.com/user_id/accounts?access_token=<user_acess_token>
the app access token that you're retrieving from
https://graph.facebook.com/oauth/access_token?client_id=ABC&client_secret=XYZ&grant_type=client_credentials
can be used to access the public data on a page - you don't need a specific 'page' access token.
this page https://developers.facebook.com/tools/explorer/ is handy for testing things out - plug in the app access token and the page url to try it out
but I am not understanding how do I get the page_access_token via an app access_token with a backend application.
Not at all …
To get a page access token, you have to have a user access token with manage_pages permission first.
(If you get a long-lived user access token, and use that to get the page access token, then the latter will not expire by default.)
I'm building a PHP application on a website to allow members of a secret Facebook group to retrieve all the YouTube links posted on the group wall. To do that I need to retrieve the feed of the group which I did using open graph. I generate an access_token thanks to graph API explorer and I managed to display the feed but it relies on the access_token which is eventually going to expire.
How can I do to be able to call the API's functions at any time with a valid access_token?
I was thinking about asking the visitors to connect with their Facebook account onto the application so that they can make a request with their own token.
Do you have leads on how I could do that?
Thanks i just created a dum app on facebook to allow oauth on my website and that did the trick.
I'm doing an IOS app with facebook SSO. Upon user granted facebook permission to the app, the app will receive an access token. The app will then make an API call to the backend with ONLY the access token.
So is the backend possible to retrieve basic user information with ONLY access token while the user's facebook id is unknown?
Looking forward to an answer. thank u=)
Yes, once you have a user access token /me can be used as a placeholder for the current user's user ID
so /me/friends returns the access token user's friends, etc
It's a bug that has been recorded and fixed by Facebook. Update your base_facebook.php to versions 3.2.2.

I am trying to understand, how facebook authentication works and how the flow should look like. I am working with Google App Engine and I have managed to obtain first the code and then access token. Using it I can for example retrieve user's friends list. This is all cool.
However, how can I store this access_token? I wan to allow my user to access different pages in my facebook app and I will need this access token on those pages. How can I store it and how can I retrieve it? Or maybe no matter which page user accesses I first need to get the code and then access token and only then can I perform some operations on his behalf?
I don't want to use javascript sdk for now. Is it possible to do it all from server side?

just store the access_token in the datastore.

It is from the facebook python sdk.

If you don't want to use javascript sdk, you need to see this document. It has all details for facebook Oauth.

While facebook redirect your user to your page assigned by redirect_uri. It will give your the code (A_CODE_GENERATED_BY_SERVER), then your server can get the user's access_token/facebook id with server side facebook api + code. Then you can login your user (set the session/cookie) and do whatever you want.
