Acquiring TWPG, who dealt with?

Question

PHP

Good afternoon. Who has experience in integrating the site and TWPG Acquiring.
The technology itself is described here: https://drive.google.com/file/d/1wNnLV7zq6t_d__y3u...
At the request of the bank, you need to generate a certificate according to the following instructions and send it to the bank, in response I received two files with the following message from the bank:
" the bank's root certificate is banktestca.crt and your merchant's root certificate is 2059055.crt, these must be used when creating a TLS connection between your site and the test TWPG."
With this, I already have an SSL certificate on the site for visitors. And this certificate is needed to communicate with TWPG
at the bottom of the document there is an example ....

function PostQW($hostname,$port,$data){

$fp = fsockopen($hostname, $port, $errno, $errstr, 30);

// Заголовок HTTPS-запроса
$headers = 'POST '.$path.' HTTP/1.0\r\n';
$headers .= 'Host: '.$hostname.'\r\n';
$headers .= 'Content-type: application/x-www-form-urlencoded\r\n';
$headers .= 'Content-Length: '.strlen($data).'\r\n\r\n';

and here the question is what HTTP header should be written to indicate the paths to these crt certificates?

Understood...

// корневой сертификат банка
  $caFile = dirname(__FILE__) . '/bank.crt';

  // сертификат торговца
  $certFile =  dirname(__FILE__) .  '/user.crt';

  // ключ сертификата
  $keyFile =  dirname(__FILE__) .  '/user.key';

  // пароль ключа (если есть)
  $privateCertPass = 'password';

  $serverURI = 'https://192.168.0.0:5555/Exec';

  $xml = '<?xml version="1.0" encoding="UTF-8"?>';
