Does anybody implemented integrating questions in an application, with sending parameters variable through the php JWT library?
Found it! Download library files from https://github.com/firebase/php-jwt.
Here is an example of use(works after embedding is enabled and the question is published):
<?php
require_once('BeforeValidException.php');
require_once('ExpiredException.php');
require_once('SignatureInvalidException.php');
require_once('JWT.php');
use \Firebase\JWT\JWT;
$secretKey = "insert_your_secret_key";
$url = 'insert_your_url';
$payload = array("resource"=>array("question"=>31), 'params' => array("startDate"=>'2017-05-01', 'endDate'=>'2017-08-31'));
$token = JWT::encode($payload , $secretKey, 'HS256');
$iframeUrl = $url."/embed/question/".$token."#bordered=true&titled=true";
?>
