Long Lived access token Facebook Page [closed]

Answer 1

1. First of all, learn the basic concepts and the different kinds of the access tokens from here

2. To get the extended User token (validity: 2months) use the code you have mentioned in the question.

   You can get the app secret from the Apps page.

3. To get a never expiring token for your fan page. Follow the simple steps:

   • Using the user token you obtained through step 2, get the list of pages/apps-

     $facebook->api("/USER_ID/accounts"); 
     

   • Get the never expiring access token for any page-

     $facebook->api("/PAGE_ID?fields=access_token");
     

(You can use Facebook's Debug Tool to check the validity of the token.)

Answer 2

To get a long-lived access token you need to follow those steps:

1. Create an Application

2. Create a Page (your account need to be "administrator" of the page)

3. Associate the application to the Page (the same way you do it when you want to add a Page Tab to a Page)

4. Get a short-lived access token with the permission "manage_pages" associated to your Application.

5. https://graph.facebook.com/oauth/authorize?client_id=APP_ID&scope=manage_pages&redirect_uri=http://www.facebook.com/connect/login_success.html

6. then https://graph.facebook.com/oauth/access_token?client_id=APP_ID&redirect_uri=http://www.facebook.com/connect/login_success.html&client_secret=APP_SECRET&code=CODE_FROM_PREVIOUS_REQUEST

7. Using the Graph API Explorer with the request /me/accounts you can see the access tokens for each Pages that you are administrator. The problem is that those access token are short-lived.

8. Convert your short-lived access token to a long-lived (extending access token):

9. https://graph.facebook.com/oauth/access_token?client_id=_APP_ID_&client_secret=_APP_SECRET_&grant_type=fb_exchange_token&fb_exchange_token=_ACCESS_TOKEN_ON_STEP_4_

   You can now test your new access token with the Access Token Debugger.
