Facebook Graph API (#190) This method must be called with a Page Access Token

Question

I get data from the Facebook insights via Facebook Graph API more than year. And recently started all my requests (like {id}/insights) to return with an error:

Answer 1

manage_pages,read_insights

This will give a user access_token , that u can use to manage pages & check insights,

But a page token became required for any /insights endpoint since 5th feb 2018

Use your manage_pages scope & user_token to get a Page access token

Send a get request to this endpoint

GET /{page-id}?fields=access_token 

Output

{
  "access_token": "{your-page-access-token}",
  "id": "{page-id}"
}

You can use the returned access token to call /insights endpoint now.

Answer 2

As I cant add comment I'll write it here.

Field name is access_token which you can check here with your page id.

https://developers.facebook.com/tools/explorer/?method=GET&path=page-id%3Ffields%3Daccess_token&version=v2.12

For PHP

If you had your script in PHP, using Facebook SDK for PHP and now it brokes, you just need to retrieve token and pass it instead of access/refresh token you were using.

//Retrieve new 'page access token'.
$token = $fbApiClient -> get( "/{$pageId}?fields=access_token") -> getGraphNode()-> asArray();

//$q is your insights query which was working until now :(
//But with page acces token it will work again.
$response = $fbApiClient -> get( $q, $token['access_token']) -> getGraphEdge();

//(...) rest of script.

I think its easily adaptable to other languages too. Also you can (and propably should) store page access token and use it wherever you need, instead of retrieving it each time.
