    .MerchantId(Environment.GetEnvironmentVariable("PAYFAST_MERCHANT_ID")!)
    .MerchantKey(Environment.GetEnvironmentVariable("PAYFAST_MERCHANT_KEY")!)
    .Passphrase(Environment.GetEnvironmentVariable("PAYFAST_PASSPHRASE")!)
    .Environment(PayFastEnvironment.Sandbox)
    .Build();

var checkout = client.BuildOnceOffCheckout(new OnceOffPaymentRequest
{
    PaymentId = "ORDER-1001",
    Amount = "100.00",
    ItemName = "Starter Plan",
    ReturnUrl = "https://example.com/payments/success",

);

// Optional post-back validation
