Amazon Pay Sdk InvalidsignatureError ⇐ Php

[Anonymous]

Я интегрирую Amazon Pay PHP SDK из документации, но получаю эту ошибку.

вот код реализации моего PHP:

$amazonpay_config = array(
'public_key_id' => 'XXXXXXXX',
'private_key' => 'my_private_key_path',
'region' => 'US',
'sandbox' => true
);
$payload = array(
'webCheckoutDetails' => array(
'checkoutReviewReturnUrl' => 'https://www.example.com/review',
'checkoutResultReturnUrl' => 'https://www.example.com/result'
),
'storeId' => 'amzn1.application-oa2-client.XXXXXXXXX'
);

$headers = array('x-amz-pay-Idempotency-Key' => uniqid());
$requestResult = [
'error' => 1,
'msg' => 'Error. Can not create checkout session.',
'checkoutSession' => null,
'payloadSign' => null
];

$client = new Client($amazonpay_config);
$resultCheckOut = $client->createCheckoutSession($payload, $headers);
$resultSignPayload = $client->generateButtonSignature($payload);

if($resultCheckOut['status'] !== 201) {
return json_encode($requestResult, true);
}
else {
$requestResult = [
'error' => 0,
'msg' => null,
'checkoutSession' => json_decode($resultCheckOut['response']),
'payloadSign' => $resultSignPayload
];
return $requestResult;
}
< /code>
Вот код реализации JS для генерации кнопки Amazon Pay. < /p>
amazon.Pay.renderButton('#amazon-pay-btn', {
// set checkout environment
merchantId: 'XXXXXXXX',
ledgerCurrency: 'USD',
sandbox: true,
checkoutLanguage: 'en_US',
productType: 'PayOnly',
placement: 'Cart',
buttonColor: 'Gold',
createCheckoutSessionConfig: {
payloadJSON: jsonResult['checkoutSession'],
signature: jsonResult['payloadSign'],
publicKeyId: 'XXXXXXXXXXX'
}
});
