如何使用payflow pro API对存储的信用卡进行充值？

Question

我正在使用PayflowPro API的PayflowNETAPI类(Payflow_dotnet.dll)来提交一个存储信用卡的事务，这样我的公司就不必这样做了（对于符合PCI的reassons）。我正在使用来自信用卡商店事务的PNREF来进行引用事务，但是我一直得到“result=2&PNREF=&respmsg=invalid tender”我尝试了授权、捕获和销售事务，它们都给出了相同的结果。我做错了什么？

我已经多次阅读了Payflow Gateway Developer Guide and Reference（https://Developer.paypal.com/docs/classic/Payflow/integration-guide/）。授权、捕获和销售事务的所有示例都在请求中包含信用卡信息。有一些小的部分解释和概述信用卡上传，但从来没有使用的结果，请求在一个参考事务。

下面是一个示例应用程序和输出

string creditCardUploadRequest = "TRXTYPE=L&TENDER=C&ACCT=4111111111111111&EXPDATE=1218&CVV2=250&BILLTOFIRSTNAME=Homer&BILLTOLASTNAME=Simpson&BILLTOSTREET=350 5th Ave&BILLTOCITY=New York&BILLTOSTATE=NY&BILLTOZIP=10118&BILLTOCOUNTRY=840&USER=<USER>&VENDOR=<VENDOR>&PARTNER=<PARTNER>&PWD=<PASSWORD>&VERBOSITY=HIGH";

var client = new PayPal.Payments.Communication.PayflowNETAPI(HostAddress: "pilot-payflowpro.paypal.com", HostPort: 443, Timeout: 90);
var ccUploadResponse = client.SubmitTransaction(ParamList: creditCardUploadRequest, RequestId: PayflowUtility.RequestId);

//place the responses into collection
var payPalCollection = new NameValueCollection();

foreach (string element in ccUploadResponse.Split('&'))
{
    string[] Temp = element.Split('=');
    payPalCollection.Add(Temp[0], Temp[1]);
}

Console.WriteLine("creditCardUploadRequest succeeded = {0}", payPalCollection.Get("RESPMSG") == "Approved");

string authorizationRequest = "TRXTYPE=A&ORIGID=" + payPalCollection.Get("PNREF") + "&INVNUM=ORD123456&AMT=50&COMMENT1=My Product Sale&USER=<USER>&VENDOR=<VENDOR>&PARTNER=<PARTNER>&PWD=<PASSWORD>&VERBOSITY=HIGH";
var authorizationResponse = client.SubmitTransaction(ParamList: authorizationRequest, RequestId: PayflowUtility.RequestId);

foreach (string element in authorizationResponse.Split('&'))
{
    Console.WriteLine(element);
}
Console.WriteLine("\nDONE");
Console.ReadKey();

输出：

creditCardUploadRequest成功=True

结果=2

PNREF=A7X08AB571EC

RESPMSG=无效投标

已完成

Answer 1

在第二次调用中，您缺少变量“tender=c”。加上这个，应该就好了。

"string authorizationRequest = "TRXTYPE=A&ORIGID=" + payPalCollection.Get("PNREF") + "&INVNUM=ORD123456&AMT=50&COMMENT1=My Product Sale&USER=<USER>&VENDOR=<VENDOR>&PARTNER=<PARTNER>&PWD=<PASSWORD>&VERBOSITY=HIGH"
