PayPal NVP部分退款全额退款,但将RefundType指定为“部分”

这是我正在使用的请求

    public string Refund_Partial(string transactionID, string refundType,string Amount)
    {
        string strCredentials = "USER=" + strUsername + "&PWD=" + strPassword + "&SIGNATURE=" + strSignature;
        string strNVP = strCredentials;
        strNVP += "&METHOD=RefundTransaction&VERSION=" + strAPIVersion;

        strNVP += "&TRANSACTIONID=" + transactionID + "&REFUNDTYPE=" + refundType + "¤cy=USD" + "&AMOUNT=" + Amount;
        //Create web request and web response objects, make sure you using the correct server (sandbox/live)
        HttpWebRequest wrWebRequest = (HttpWebRequest)WebRequest.Create(strNVPSandboxServer);
        //Set WebRequest Properties
        wrWebRequest.Method = "POST";
        // write the form values into the request message
        StreamWriter requestWriter = new StreamWriter(wrWebRequest.GetRequestStream());
        requestWriter.Write(strNVP);
        requestWriter.Close();
        // Get the response.
        HttpWebResponse hwrWebResponse = (HttpWebResponse)wrWebRequest.GetResponse();
        StreamReader responseReader = new StreamReader(wrWebRequest.GetResponse().GetResponseStream());
        // and read the response
        string responseData = responseReader.ReadToEnd();
        responseReader.Close();
        return responseData;
    }

任何人都可以让我知道我需要包含更多参数才能获得部分退款吗?

您可以更改currencyCode的参数值和Amount,From

"¤cy=USD" + "&AMOUNT=" + Amount

"CURRENCYCODE=USD" + "&AMT=" + Amount

查看RefundTransaction API Operation (NVP)

可能是PayPal正在寻找不存在的AMT参数,这就是为什么它在完全退款
