Paypal SetExpressCheckout ile ilgili sorunlar ASP.net'de NVP API'sini kullanırken,

Question

Merhaba, Facebook oyunum ve Paypal'ın ekspres ödeme ödeme hizmeti arasındaki geçişi uyguluyorum.

Web sitem ASP.net'de geliştirilmiştir ve entegrasyon için NVP API kullanıyorum.

Sorun şu ki, 10400 hatası almaya devam ediyorum - Sipariş Toplamı eksik.

My kodudur:

// Set the key/value pairs to send in the request 
var kvpl = new List<KeyValuePair<string, string>>(); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_PAYMENTACTION", "Sale")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_AMT", "23.00")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_ITEMAMT", "15.00")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_TAXAMT", "5.00")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_SHIPPINGAMT", "1.00")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_HANDLINGAMT", "1.00")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_INSURANCEAMT", "1.00")); 
kvpl.Add(new KeyValuePair<string, string>("PAYMENTREQUEST_0_CURRENCYCODE", "ILS")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_NAME0", "The name of product 1")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_NUMBER0", "5543312")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_DESC0", "The description of product 1")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_AMT0", "10.00")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_QTY0", "1")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_NAME1", "The name of product 2")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_NUMBER1", "4431234")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_DESC1", "The description of product 2")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_AMT1", "5.00")); 
kvpl.Add(new KeyValuePair<string, string>("L_PAYMENTREQUEST_0_QTY1", "1"));  
kvpl.Add(new KeyValuePair<string, string>("ALLOWNOTE", "1")); 
kvpl.Add(new KeyValuePair<string, string>("NOSHIPPING", "1")); 

// SetExpressCheckout 
bool ret = test.ShortcutExpressCheckout(amt, ref token, ref retMsg, kvpl); 

// Check return value 
if (ret) 
{ 
    // Success, store the token in the session and redirect to Paypal 
    session["token"] = token; 
    Response.Redirect(retMsg); 
} 
else 
{ 
    // Something went wrong 
    Response.Redirect("APIError.aspx?" + retMsg); 
} 

ShortcutExpressCheckout yönteminin kodudur:

public bool ShortcutExpressCheckout(string amt, ref string token, ref string retMsg, List<KeyValuePair<string, string>> customParams) 
{ 
    string host = "www.paypal.com"; 
    if (bSandbox) 
    { 
     pendpointurl = "https://api-3t.sandbox.paypal.com/nvp"; 
     host = "www.sandbox.paypal.com"; 
    } 

    string returnURL = "http://localhost:50020/" + "ConfirmPayment.aspx"; 
    string cancelURL = "http://localhost:50020/" + "CancelPayment.aspx"; 

    var encoder = new NVPCodec(); 
    encoder["VERSION"] = "72.0"; 
    encoder["METHOD"] = "SetExpressCheckout";   
    encoder["RETURNURL"] = returnURL; 
    encoder["CANCELURL"] = cancelURL; 

    if (customParams != null) 
    { 
     customParams.ForEach(kvp => encoder[kvp.Key] = kvp.Value); 
    } 

    string pStrrequestforNvp = encoder.Encode(); 
    string pStresponsenvp = HttpCall(pStrrequestforNvp); 

    var decoder = new NVPCodec(); 
    decoder.Decode(pStresponsenvp); 

    string strAck = decoder["ACK"].ToLower(); 
    if (strAck != null && (strAck == "success" || strAck == "successwithwarning")) 
    { 
     token = decoder["TOKEN"]; 

     string ECURL = "https://" + host + "/cgi-bin/webscr?cmd=_express-checkout" + "&token=" + token; 

     retMsg = ECURL; 
     return true; 
    } 
    else 
    { 
     retMsg = "ErrorCode=" + decoder["L_ERRORCODE0"] + "&" + 
       "Desc=" + decoder["L_SHORTMESSAGE0"] + "&" + 
       "Desc2=" + decoder["L_LONGMESSAGE0"]; 

     return false; 
    } 
}

Ben paypal sağlar dokümantasyon ve bu konuda birçok mesajları gözden ama ben yanlış yapıyorum bulamadık. Eski bir sürümünü kullandığınız için

Herhangi bir yardım takdir edilecektir,

Answer 1

Sipariş Toplam parametre, eksik. Gösterdiğiniz API isteği ve yanıtınız eşleşmiyor.

Aslında sürüm 2.3 yayınlıyorsan değil, sürüm 72.0 .. API tepkisini bakın:
