Http notifications of QIWI wallet?

Question

PHP

Good day!
Tell me please. I accept payment on the kiwi website, after which http notifications should come to the server, but I can’t understand why the instruction doesn’t work, I used poison before, everything worked clearly there. Here is the Qiwi documentation: Bill payment notifications (there is also an example of an incoming request).
Here is my code:

<?php
  $secret_key = 'SECRETSECRETKEYKEY';

  $sha256_hash_header = $_SERVER['HTTP_X_API_SIGNATURE_SHA256']; // Получаю заголовок

  $entity_body = file_get_contents('php://input');	// Декодирую тело входящего запроса
  $array_body = json_decode($entity_body, 1);			// в обычный массив

  $amount_currency = $array_body['bill']['amount']['currency'];
  $amount_value = $array_body['bill']['amount']['value'];
  $billId = $array_body['bill']['billId'];
  $siteId = $array_body['bill']['siteId'];
  $status_value = $array_body['bill']['status']['value'];

  $invoice_parameters = $amount_currency . '|' . $amount_value . '|' . $billId . '|' . $siteId . '|' . $status_value;

  $sha256_hash = hash_hmac('sha256', $invoice_parameters, $secret_key);

  if ($sha256_hash_header == $sha256_hash && !empty($sha256_hash_header)) {
    // выполняю какой-то код, если все верно
  } else {
    http_response_code(404);
    die();
  }
?>

Why it doesn't work, help the teapot figure it out
