Facebook Marketing API. Geographic search

问题

I am trying to get list of all cities of a country from Facebook.

I started from FB documentation of v2.9 here: Facebook Marketing API

And tried of getting list of cities as described using curl:

curl -G \
  -d 'location_types=["city"]' \
  -d 'type=adgeolocation' \
  -d 'q=dub' \
  -d 'access_token=<MY_TOKEN>' \
  https://graph.facebook.com/v2.9/search

But it returns empty json. If i remove q=dub parameter it still returns empty data. But if i put country as a type of location, then it nicely returns country list. What am i doing wrong?

It would be also appriciated if you could point how to make it return cities for certain country. There is country_code parameter, but it also doesn't work.

Little weird but I was trying this for last few hours and it turns out the search for city is not available when you are using access token that is of a Sandbox account.

I tried the same api endpoints with real facebook advert account's access token and it works.

as of how this works, here is a bit of code that might help future readers :

//Include Facebook SDK classes
//use FacebookAds\Api;
//use FacebookAds\ApiRequest;
//use FacebookAds\Object\TargetingSearch;
//use FacebookAds\Object\Search\TargetingSearchTypes;

function searcher() {
    $fbutils = new FacebookUtils(16);
    $account_id = $fbutils->getAccountID();
    $accessToken = $fbutils->getAccessToken($account_id);
    Api::init(fb_app_id, fb_app_secret, $accessToken);
        $result = TargetingSearch::search(
            TargetingSearchTypes::GEOLOCATION, null, 'dub', array(
            'location_types' => array('city'),
    ));
    $fb = new Facebook([
        'app_id' => fb_app_id,
        'app_secret' => fb_app_secret,
        'default_graph_version' => 'v2.10',
        'default_access_token' => $accessToken
    ]);
    $fb = $result;
        $objects = $result->getArrayCopy();
        $objects_arr = array();
    do {
        foreach ($objects as $object) {
            $objects_arr[] = $object->getData();
        }
    } while ($objects = $fb->next($objects));

    echo "<pre>";
    print_r($objects_arr);
    exit;
}

Note : replace constants and variables with your data and this should work for searching cities and use pagination and print result as a pretty array.
