Question

我想知道PayPal是否有支付服务允许用户在我的网站上输入他们的信用卡详细信息（用户甚至不知道他们是通过PayPal付款）。然后我需要确保它处理重复付款和退款。基本上我需要创建一个实现以下功能的paypal服务：

public interface IPaymentService {
    Response ValidateCard(NetworkCredential credential, int transactionID, decimal amount, string ipAddress, CardDetails cardDetails, Address billingAddress, Options options);
    Response RepeatCard(NetworkCredential credential, int oldTransactionID, int newTransactionID, decimal amount);
    Response RefundCard(NetworkCredential credential, int refundedTransactionID, int newTransactionID, decimal amount);
}

public class Address {
    public virtual string Address1 { get; set; }
    public virtual string Address2 { get; set; }
    public virtual string Address3 { get; set; }
    public virtual string Town { get; set; }
    public virtual string County { get; set; }
    public virtual Country Country { get; set; }
    public virtual string Postcode { get; set; }
}

public class CardDetails {
    public string CardHolderName { get; set; }
    public CardType CardType { get; set; }
    public string CardNumber { get; set; }
    public int ExpiryDateMonth { get; set; }
    public int ExpiryDateYear { get; set; }
    public string IssueNumber { get; set; }
    public string Cv2 { get; set; }
}

public class Response {
    public bool IsValid { get; set; }
    public string Message { get; set; }
}

public class Options {
    public bool TestStatus { get; set; }
    public string Currency { get; set; }
}

通常这与其他支付服务提供商（例如PayPoint（肥皂服务）和SagePay）非常微不足道。

阅读paypal文档让我头疼，所以我想我会在这里问。真的很感激帮助。感谢

是的，他们这样做。查看此文档。

直接付款api允许您输入持卡人的信息，然后通过PayPal系统处理。

//process payment
            Paypal toPayment = new Paypal();
            toPayment.BillingAddress = new Address(txt_BillingAddr1.Text, txt_BillingAddr2.Text, txt_BillingCity.Text, ddl_BillingState.SelectedValue, txt_BillingZip.Text, "");
            toPayment.BillingCountry = com.paypal.soap.api.CountryCodeType.US;
            toPayment.BillingFName = txt_BillingFName.Text;
            toPayment.BillingLName = txt_BillingLName.Text;
            toPayment.BillingMName = txt_BillingMName.Text;
            toPayment.BillingPhoneNumber = txt_BillingPhone.Text;
            toPayment.BillingSuffix = txt_BillingSuffix.Text;
            toPayment.ContactPhoneNumber = txtPhone.Text;
            toPayment.CreditCardExpireMonth = Convert.ToInt32(ddl_CCExpireMonth.SelectedIndex + 1);
            toPayment.CreditCardExpireYear = Convert.ToInt32(ddl_CCExpireYear.SelectedValue);
            toPayment.CreditCardNumber = txt_CreditCard.Text;
            toPayment.CreditCardSecurityCode = txt_CCID.Text;
            switch (lst_CCTypes.SelectedValue)
            {
                case "Visa":
                    toPayment.CreditCardType = com.paypal.soap.api.CreditCardTypeType.Visa;
                    break;
                case "MasterCard":
                    toPayment.CreditCardType = com.paypal.soap.api.CreditCardTypeType.MasterCard;
                    break;
                case "AmericanExpress":
                    toPayment.CreditCardType = com.paypal.soap.api.CreditCardTypeType.Amex;
                    break;
                case "Discover":
                    toPayment.CreditCardType = com.paypal.soap.api.CreditCardTypeType.Discover;
                    break;
            }
            toPayment.UserHostAddress = Request.UserHostAddress;
            toPayment.OrderTotal = StaticMethods.getDecimal(lbl_TotalPrice_cout.Text, 0);

            //set API Profile
            toPayment.APIProfile = Master.PayPal_API_Profile;

            DoDirectPaymentResponseType toResponse = new DoDirectPaymentResponseType();
            toResponse = toPayment.processDirectPaymentTransaction();

这里有一点对你来说......这是我工作的实际生产网站的实际代码，通过paypal付款

toResponse包含一个Ack属性....所以你可以做类似

的事情

switch(toResponse.Ack)
{
case AckCodeType.Failure;
     // The card is bad. void transaction.
     lblResponse = toResponse.Errors[0].LongMessage;
     Break;
case AckCodeType.Success
     // The card is good.  Go forward with process
}

是的，PayPal在Website Payments Pro下提供此功能。您可以阅读更多相关信息here。

第一个流程是直接付款，第二个流程是快速结账。客户在直接付款下在您的网站上输入卡详细信息。
