ОШИБКА Adyen: [status] = & gt; 403 [errorCode] = & gt; 010 [сообщение] = & gt; Не допускается [errorType] = & gt; безопасность

Я пытаюсь использовать JSON API, чтобы сделать (тестовый) платеж через ADYEN.

Вот код (я получил этот пример от Github -> Adyen -> adyen-php-sample-code:

    <?php
/**
* Create Payment through the API (HTTP Post)
*
*
* Please note: using our API requires a web service user. Set up your Webservice
* user: Adyen Test CA >> Settings >> Users >> ws@Company. >> Generate Password >> Submit

*/

/**
* A payment can be submitted by sending a PaymentRequest
* to the authorise action of the web service, the request should
* contain the following variables:

Кто-нибудь сталкивался с этой проблемой раньше? Как я могу это исправить?
Я использовал почти любой пример в github, но есть только несколько ошибок, которые задокументированы, остальные …. ничего ..

Пожалуйста помоги мне с этим. Спасибо
