Create pass for passbook in php

I am trying to create dynamic coupons for my application. I have a PHP server that creates them. But I do not know why they do not work in a savings book.

If I create a passage from the terminal, it works fine. But in PHP with PHP-PKPass.

I left the PHP code below, it appears on my computer, but it is not added to the savings book (also if I send it by email)

Im 100% sure passTypeIdentifier, teamIdentifier, Certificate and WWDR are 100% correct

Note: all images exist

<?php
include ("conexion.php");
require('passpk/PKPass.php');

if (isset($_GET['cupon']) and $_GET['cupon'] != '' and $_GET['cupon'] > 0) {

    $cuponID = $_GET['cupon'];


    $pass = new PKPass\PKPass();

    $pass->setCertificate('./Certificate.p12');  // 2. Set the path to your Pass Certificate (.p12 file)
    $pass->setCertificatePassword('*******');     // 2. Set password for certificate
    $pass->setWWDRcertPath('./WWDR.pem'); // 3. Set the path to your WWDR Intermediate certificate (.pem file)
