Question

i need to extend my facebook access token, I\'m calling this:

https://graph.facebook.com/oauth/access_token? 
client_id={MY PAGE ID}&
client_secret={THE          


        

Answer 1

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)

   http://facebook.com/add.php?api_key=*YOUR_APP_ID*&pages=1&page=*YOUR_PAGE_ID*
   

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

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

5. 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.

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

   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_
   

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

Scenario 5: Page Access Tokens

When a user grants an app the manage_pages permission, the app is able to obtain page access tokens for pages that the user administers by querying the [User ID]/accounts Graph API endpoint. With the migration enabled, when using a short-lived user access token to query this endpoint, the page access tokens obtained are short-lived as well.

Exchange the short-lived user access token for a long-lived access token using the endpoint and steps explained earlier. By using a long-lived user access token, querying the [User ID]/accounts endpoint will now provide page access tokens that do not expire for pages that a user manages. This will also apply when querying with a non-expiring user access token obtained through the deprecated offline_access permission.
