Question

Facebook documentation says offline_access is depreca ted.How do I extend the access token for 60 day?

I did enabled deprecated offline_access from advanced settings for app.

Answer 1

you can try to two ways: 1. enable the offline deprecation functionality, and grab the exchanged token value in available and then run cUrl functionality. After running the cUrl just pass the response value in var_dump().. you could see the access token and the expires date..

1. you will get different value for the opposite process of (1).

Answer 2

You can use https://developers.facebook.com/docs/howtos/login/extending-tokens/ for long lived access tokens, or https://developers.facebook.com/docs/howtos/login/login-as-app/ for non-expiring app access tokens. But you probably need the first.

 function fb_renew_access_token($args=array()){
     $token_url = "https://graph.facebook.com/oauth/access_token?client_id=".$args["app_id"]."&client_secret=".$args["app_secret"]."&grant_type=fb_exchange_token&fb_exchange_token=".$args["old_token"];

     $c = curl_init();
     curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
     curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false);
     curl_setopt($c, CURLOPT_URL, $token_url);
     $contents = curl_exec($c);
     $err  = curl_getinfo($c,CURLINFO_HTTP_CODE);
    curl_close($c);

    $paramsfb = null;
    parse_str($contents, $paramsfb);

    return $paramsfb;
 }
 //to get the extended access token
 $extended_access = fb_renew_access_token(array("app_id"=>"4545454544s45454545","app_secret"=>"sdfgds2fg4d2f54g5df4gdsdsfgdsfg54dfg","old_token"=>"54sdf54sd54f35asdgs4ghdsd5sh4d5trh4djhdfj45fdh"));
