As I knew there is a way to get access token via https://developers.facebook.com/tools/explorer.
Is there other way to get page_access_token by API?
I want to post request to add app to facebook page but it require a page_access_token as below:
https://graph.facebook.com/myPageId/tabs/?app_id=myAppId&access_token=myPageAccessToken
Thanks.
Yes you can. The current user must be an administrator of this page;
extended permission needed - manage_pages
refer url: https://developers.facebook.com/docs/reference/api/page/
Try this:
$config = array(
'appId' => FB_APP_ID,
'secret' => FB_SECRET_KEY,
'cookie' => true // enable optional cookie support
);
$facebook = new Facebook($config);
// See if there is a user from a cookie
$user = $facebook->getUser();
$params = array(
'scope' => 'manage_pages',
'redirect_uri' => FB_APP_URL,
);
$loginUrl = $facebook->getLoginUrl($params);
<script> window.top.location.href = '<?php echo $loginUrl ?>'; </script>
