Question

我使用PayPal Express Checkout和Classic API在我的网站上付款。以下是API文档：

https://developer.paypal.com/docs/classic/api/merchant/DoExpressCheckoutPayment_API_Operation_SOAP/

要使用该服务，我使用以下库：

https://www.nuget.org/packages/PayPalMerchantSDK/

我的任务是针对PayPal交易提供欺诈信息。我们想要显示的信息是地址验证（AVS）和安全代码验证（CSC）。

为了测试这一点，我试图记录欺诈信息。这是我创建Express Checkout请求的代码，然后获得响应：

var request = new DoExpressCheckoutPaymentReq() {
    DoExpressCheckoutPaymentRequest = new DoExpressCheckoutPaymentRequestType() {
        DoExpressCheckoutPaymentRequestDetails = new DoExpressCheckoutPaymentRequestDetailsType() {
            Token = details.Token,
            PaymentAction = PaymentActionCodeType.SALE,
            PayerID = details.PayerInfo.PayerID,
            PaymentDetails = details.PaymentDetails
        },
        ReturnFMFDetails = 1
    }
};

var response = DoExpressCheckoutPayment(request);

上面注意我添加了以下行：

ReturnFMFDetails = 1

根据文档，这应该返回适当的欺诈信息。最后，我将以下代码添加到底部以记录欺诈信息：

var sb = new StringBuilder();

try {
    var paymentInfo = response.DoExpressCheckoutPaymentResponseDetails.PaymentInfo;

    for (var i = 0; i < paymentInfo.Count; i++) {
        var fmfDetails = paymentInfo[i].FMFDetails;

        if (fmfDetails != null) {
            if (fmfDetails.AcceptFilters != null) {
                foreach (var filter in fmfDetails.AcceptFilters.Filters) {
                    sb.AppendLine("Accept Filter (" + i + "): " + filter.Id + " - " + filter.Name);
                }
            }

            if (fmfDetails.DenyFilters != null) {
                foreach (var filter in fmfDetails.DenyFilters.Filters) {
                    sb.AppendLine("Deny Filter (" + i + "): " + filter.Id + " - " + filter.Name);
                }
            }

            if (fmfDetails.PendingFilters != null) {
                foreach (var filter in fmfDetails.PendingFilters.Filters) {
                    sb.AppendLine("Pending Filter (" + i + "): " + filter.Id + " - " + filter.Name);
                }
            }

            if (fmfDetails.ReportFilters != null) {
                foreach (var filter in fmfDetails.ReportFilters.Filters) {
                    sb.AppendLine("Report Filter (" + i + "): " + filter.Id + " - " + filter.Name);
                }
            }
        }
    }
} catch (Exception ex) {
    sb.AppendLine(ex.Message);
}

Logger.Log(sb.ToString());

但是，记录的信息始终为空。如果有人能告诉我我做错了什么，我会很感激。感谢

在使用PayPal Fraud Management Filters（FMF）之前，您必须setup & configure帐户过滤设置中的过滤条件。默认情况下，过滤器不会设置，也不会返回任何信息。

一旦你得到它设置＆amp;如果已配置，则应开始接收相应的FMF信息。

PayPal Express Checkout（经典API）欺诈信息未返回
