How to fix err_access in LiqPay?

Question

Yii

Good day! I make a request for liqpay as shown in the documentation with my public and private keys, but the problem is that the result comes with an "err_access" error. Help. Thanks

$fake_params = [
            'action'         => 'pay',
            'version'        => 3,
            'public_key'     => 'i88077466459',
            'sandbox'        => '1',
            'phone'          => '[phone]',
            'amount'         => 1,
            'currency'       => 'USD',
            'description'    => 'description text',
            'order_id'       => 'order_id_1',
            'card'           => '4731195301524634',
            'card_exp_month' => '03',
            'card_exp_year'  => '22',
            'card_cvv'       => '111',
            'ip'             => Yii::$app->request->getUserIP()
        ];

        $liqpay = new \LiqPay('i88077466459', 'wR2rIjUhIQpZO5ro57eKimWX03LZwnhAJklYqndg');

        echo '<pre>';
        var_dump($liqpay->api('request', $fake_params));
        echo '<pre>';
        die;

and in the end

stdClass Object
(
    [result] => ok
    [status] => error
    [err_code] => err_access
    [err_description] => err access
)

Faced the same problem. As the liqpay support answered (by the way, I recommend writing to them in the dialogue on the site, because they didn’t answer me by mail) - in order to use this method, you must have a PCI DSS certificate. In short, this certificate confirms that you can safely store other people's bank card passwords on your server. And this certificate is not so easy to get.
Therefore, liqpay recommends using a different method. In this case, an iframe from liqpay will be loaded on your site and you will no longer have access to the client's card data.
