Docapture 方法 paypal api 中的交易 ID 无效

Question

我正在执行 DoCapture 并使用 DoDirectPayment 的交易 ID。但每次我捕获付款时，它都会显示“无效的交易 ID”。当我尝试从信用卡直接付款中获取一笔付款时，就会发生这种情况，而且这种信用卡付款是通过 DoDirectPayment 方法进行的。 但是，如果通过转到我的 PayPal 帐户并完成我的交易来进行 expressCheckout，这也会给我交易 ID。如果我使用此交易 ID 捕获付款，则付款过程成功完成！我不知道发生了什么事！请任何人帮助我摆脱问题！ 我正在使用 PayPal API 版本 59.0 我的示例代码

                Session["stage"] = ASPDotNetSamples.Constants.ENVIRONMENT; //SandBox Environment
                //here my api credentials
                SetProfile.SessionProfile = SetProfile.CreateAPIProfile(ASPDotNetSamples.Constants.API_USERNAME,
                    ASPDotNetSamples.Constants.API_PASSWORD, ASPDotNetSamples.Constants.API_SIGNATURE, "", "",
                    ASPDotNetSamples.Constants.ENVIRONMENT);


                //NVPCallerServices caller = PayPalAPI.PayPalAPIInitialize();
                //NVPCodec encoder = new NVPCodec();
                com.paypal.sdk.services.NVPCallerServices caller = PayPalAPI.PayPalAPIInitialize();
                NVPCodec encoder = new NVPCodec();

                encoder["METHOD"] = "DoCapture";
                encoder["TRXTYPE"] = "D";
                encoder["AUTHORIZATIONID"] = authorization_id.; //the authrization id i got from the dodirectpayment
                encoder["COMPLETETYPE"] = CompleteCodeType; //completecodetype is completed
                double dAmount = Convert.ToDouble(actualAmount);
                encoder["AMT"] = String.Format("{0:0.00}", dAmount);                       

                string pStrrequestforNvp = encoder.Encode();
                string pStresponsenvp = caller.Call(pStrrequestforNvp);

                NVPCodec decoder = new NVPCodec();
                decoder.Decode(pStresponsenvp);
                string parentTransactionID = decoder["PARENTTRANSACTIONID"];
                string strAck = decoder["ACK"];

                if (strAck != null && (strAck == "Success" || strAck == "SuccessWithWarning"))
                {
                    string pStrResQue = "AUTHORIZATIONID=" + decoder["AUTHORIZATIONID"] + "&" +
                        //"PAYMENTSTATUS=" + decoder["PAYMENTSTATUS"] + "&" +
                                        "PAYMENTSTATUS=" + CompleteCodeType + "&" +
                                        "AMT=" + decoder["AMT"] + "&" +
                                        "TRANSACTIONID=" + decoder["TRANSACTIONID"];                        
                       // if  Payment is done successfully

                }
                else
                {
                     // if Payment is pending

                    string pStrError = "ErrorCode=" + decoder["L_ERRORCODE0"] + "&" +
                                       "Desc=" + decoder["L_SHORTMESSAGE0"] + "&" +
                                       "Desc2=" + decoder["L_LONGMESSAGE0"];                        
                    Response.Redirect("APIError.aspx?" + pStrError);
                }

提前致谢！

看到这个

com.paypal.sdk.services.NVPCallerServices caller = PayPalAPI.PayPalAPIInitialize();
    NVPCodec encoder = new NVPCodec();
    encoder["METHOD"] = "DoDirectPayment";
    encoder["PAYMENTACTION"] = "Authorization";
    //encoder["AMT"] = hfHoldAmount.Value.ToString();
    encoder["AMT"] = hfHoldAmount.Value.ToString();
    encoder["CREDITCARDTYPE"] = ddlCardType.SelectedValue;
    encoder["ACCT"] = txtCardNnumber.Text.Trim();
    encoder["EXPDATE"] = (ddlExpMonth.SelectedValue.Length == 1 ? "0" + ddlExpMonth.SelectedValue : ddlExpMonth.SelectedValue) + ddlExpYear.SelectedValue;
    encoder["CVV2"] = txtCVCode.Text.Trim();
    encoder["FIRSTNAME"] = txtFirstName.Text.Trim();
    encoder["LASTNAME"] = txtLastName.Text.Trim();
    encoder["STREET"] = txtAddress.Text.Trim();
    encoder["CITY"] = txtCity.Text.Trim();
    encoder["STATE"] = ddlStateProvince.Items.FindByValue(ddlStateProvince.SelectedValue).Text;
    encoder["ZIP"] = txtZipCode.Text.Trim();
    encoder["COUNTRYCODE"] = "US";
    encoder["CURRENCYCODE"] = "USD";
