I am working on a application where i am asking for appid, secret and page access token from user. I do not want to ask Page Id. so how can i get Page Id from page_access_token.?
I do not want to ask Page Id. so how can i get Page Id from page_access_token?
You can either debug the access token via an API call - but that would require that the token was issued for your app.
Or you simply make an API call for /me using the page access token - that will return the page id.

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:

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 am administrator of facebook page which DOES NOT have a classic facebook account assigned. So I am not able to create any facebook application as you can see in Picture 1. How can I obtain long lived (never expiring) page access token, which I need to use Graph API? I need to post messages to the facebook page from my server.
Thanks for advice
You do need a User account that is admin of the Facebook Page in order to get a Page Token. Without a User account, it is not possible.
Here´s what you need to do:
Authorize the User account in the App - which means, get a User Access Token
Extend the User Token
Get an Extended Page Token with /me/accounts or /[page-id]?fields=access_token
Some Links for more information:
https://developers.facebook.com/docs/facebook-login/access-tokens/
http://www.devils-heaven.com/facebook-access-tokens/
http://www.devils-heaven.com/extended-page-access-tokens-curl/
I use the following code:
$access_token = $object->getAccessToken();
This method sometimes generated an access token (118-char string)
and sometimes it's a 49-character string with a pipe symbol which does not work properly.
Can I use same access token to post feed with different user id?
Why do access tokens not work properly in safari with iframe & non iframe?
Is there any link do access token documentation?
Firs of all there are two type of tokens that are generated by Facebook
Application without User
When there is no user using the application the application uses what is known as "App Access Token". The app access token can be represented as
<APP ID>|<APP Secret>
This token can retrieve all the public domain information for different Objects in Facebook, like it can be used to retrieve basic information about a User with specific ID, likes on a Public Page, Public Posts on a Page.
Application with User
When User authorizes the application Facebook generates a "User Access Token" which is the access token with longer length. You can't use User Access Token of one user to do the actions on behalf of another User and if you try the action will be done as the User for whom the token was generated for(If you are not Using Extended Access Token it will also expire).
There is issue in setting the Cookies within an iframe in the safari due to which there is some issues in the application working.
For further clarification on Access Token check this documentation
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 have a Facebook application that users can add to their Facebook business Page(s) as a Page Tab app. It doesn't require any extended permissions for the user. I'm wondering if it's possible to use my app access_token and make calls against the Facebook Graph API to retrieve information about age-restricted Pages?
No, if a page is restricted demographically (e.g. for alcohol) you MUST use a user access token from a user who meets those restrictions, or a Page access token for the page itself.
An app access token will not work for such an API call
If the owner of that access token can view the data on facebook you can get any data using that access token not mater if its block for the others .
