Getting a fatal Error call to unidentified method Pass::_createpass() - php

Question

Can someone please help. I am getting a fatal error on the following PHP script.
I am getting an error "unidentified method Pass::_createpass()" whick relates to the second last line of the code below.
<?php
$engine = Pass::start('xxxxxxxxxxxxxxxx');
$pass = $engine->createPassFromTemplate(xxxxxxxxxxxxxx);
$engine->redirectToPass($pass);
if (!function_exists('curl_init')) {
throw new Exception('Pass needs the CURL PHP extension.');
}
if (!function_exists('json_decode')) {
throw new Exception('Pass needs the JSON PHP extension.');
}
$engine = Pass::start($appKey);
$values = array(
'first' => 'John',
'last' => 'Platinum',
);
$images = array(
'thumbnail' => 'image1.jpg'
);
$pass = $engine->createPassFromTemplate(5688667418918912, $values, $images);
$passData = $engine->downloadPass($pass);
$engine->redirectToPass($pass);
class Pass
{
private $_appKey = null;
private $_endpoint = 'https://pass.center/api/v1';
private $_debug = false;
private static $_instance = null;
private static $_imageTypes = array('icon', 'logo', 'strip', 'thumbnail', 'background', 'footer');
const VERSION = '0.5';
const USER_AGENT = 'PassSDK-PHP/0.5';
public function __construct($appKey = null, $endpoint = null, $debug = false)
{
if (is_null($appKey)) {
throw new Exception('App Key required');
}
$this->_appKey = $appKey;
if ($endpoint !== null) {
$this->_endpoint = $endpoint;
}
$this->_debug = $debug;
}
public static function start($appKey = null, $endpoint = null, $debug = false)
{
if (self::$_instance == null) {
self::$_instance = new self($appKey, $endpoint, $debug);
}
return self::$_instance;
}
public function createPassFromTemplate($templateId, $values = array(), $images = array())
{
$resource = sprintf("https://xxxxxxx/api/v1/templates/names/Test/pass", $templateId);
return $this->_createPass($resource, $values, $images);
}
}
I hope someone can help me as I am not familiar with Functions PHP.
Thanks All

The function createPass is missing.
You need something like this:
/**
* Prepares the values and image for the pass and creates it
*
* #param string $resource Resource URL for the pass creation
* #param array $values Values
* #param array $images Images
* #return object Pass
*/
private function _createPass($resource, $values, $images)
{
$multipart = count($images) > 0;
if ($multipart) {
$content = array();
foreach ($images as $imageType => $image) {
$this->_addImage($image, $imageType, $content, $imageType);
}
var_dump($content);
// Write json to file for curl
$jsonPath = array_search('uri', #array_flip(stream_get_meta_data(tmpfile())));
file_put_contents($jsonPath, json_encode($values));
$content['values'] = sprintf('#%s;type=application/json', $jsonPath);
} else {
$content = $values;
}
return $this->_restCall('POST', $resource, $content, $multipart);
}
