use ReceiptValidator\AppleAppStore\ReceiptUtility;
use ReceiptValidator\AppleAppStore\Validator as AppleValidator;
use ReceiptValidator\Environment;

// Credentials
$signingKey = file_get_contents($root . '/examples/SubscriptionKey_RA9DAYVX3X.p8');
$keyId = 'RA9DAYVX3X';
$issuerId = 'xxxxxx-xxxx-xxxx-xxxx-xxxxxxx';
$bundleId = 'com.myapp';

$receiptBase64Data = '...'; // your app receipt here
$transactionId = ReceiptUtility::extractTransactionIdFromAppReceipt($receiptBase64Data);

$validator = new AppleValidator(
    signingKey: $signingKey,
    keyId: $keyId,
    issuerId: $issuerId,
    bundleId: $bundleId,
    environment: Environment::PRODUCTION
);

try {
    $response = $validator->setTransactionId($transactionId)->validate();
} catch (Exception $e) {
    echo 'Error validating transaction: ' . $e->getMessage() . PHP_EOL;
    exit(1);
}

echo 'Validation successful.' . PHP_EOL;
echo 'Bundle ID: ' . $response->getBundleId() . PHP_EOL;
echo 'App Apple ID: ' . $response->getAppAppleId() . PHP_EOL;

foreach ($response->getTransactions() as $transaction) {
    echo 'getProductId: ' . $transaction->getProductId() . PHP_EOL;
    echo 'getTransactionId: ' . $transaction->getTransactionId() . PHP_EOL;

    if ($transaction->getPurchaseDate() != null) {
