Paypal payKey 让我支付错误

Question

我正在尝试创建一个 API 调用来创建分期付款。在创建AdaptivePaymentService 并调用Pay 方法后，它返回一个显示SUCCESS 的PayResponse。但是，当我收到payKey 并打开https://www.sandbox.paypal.com/webscr?cmd=_ap-payment&paykey= 的页面时，它会将我带到一些随机页面，该页面通常会显示一些错误，类似于“此交易已被批准。请访问您的 PayPal 帐户概览以查看详细信息。”，在右上角，它会显示“Fiverr.com”或其他一些随机网页。我已经验证我收到的payKey 是与SUCCESS 消息一起发送的，所以我不明白为什么这是无效的。以下代码是我正在使用的。

        ReceiverList receiverList = new ReceiverList();
        receiverList.receiver = new List<Receiver>();
        RequestEnvelope requestEnvelope = new RequestEnvelope("en_US");

        Dictionary<string, string> configurationMap = new Dictionary<string, string>();

        configurationMap.Add("account1.apiUsername", "----");
        configurationMap.Add("account1.apiPassword", "----");
        configurationMap.Add("account1.apiSignature", "----");
        configurationMap.Add("account1.applicationId", "APP-80W284485P519543T");

        configurationMap.Add("mode", "sandbox");

        Receiver receiver1 = new Receiver();
        receiver1.amount = ((decimal?)9.00);
        receiver1.email = "rbxtrade-seller@gmail.com";

        receiverList.receiver.Add(receiver1);

        Receiver receiver2 = new Receiver();
        receiver2.amount = ((decimal?)2.00);
        receiver2.email = "rbxtrade-buyer@gmail.com";

        receiverList.receiver.Add(receiver2);

        PayRequest request = new PayRequest(requestEnvelope, "PAY", "https://devtools-paypal.com/guide/ap_parallel_payment/dotnet?cancel=true", "USD", receiverList, "https://devtools-paypal.com/guide/ap_parallel_payment/dotnet?success=true");

        AdaptivePaymentsService service = new AdaptivePaymentsService(configurationMap);
        PayResponse response = service.Pay(request);

        if (!response.responseEnvelope.ack.ToString().Trim().ToUpper().Equals(AckCode.FAILURE.ToString()) && !response.responseEnvelope.ack.ToString().Trim().ToUpper().Equals(AckCode.FAILUREWITHWARNING.ToString()))
        {
            Process.Start("https://www.sandbox.paypal.com/webscr?cmd=_ap-payment&paykey=" + response.payKey); //opens the webpage
        }
        else
        {
            Console.WriteLine("E:" + String.Join("\n", response.error.Select((x) => x.message)));
        }

我目前在 java 中遇到了这个问题。

尝试返回：“https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&paykey=”+ paykey。它应该与此一起使用。

这是我找到的所有东西，但它对我不起作用。
