購物車寬運費與集成錯誤代碼：10413

Question

我想整合payapl通過沙箱爲我的網站。

我可以發送多個項目貝寶它工作正常。但我想設置CART-WIDE運費，並將其發送到paypal。

我得到錯誤代碼：

10413 ("ErrorCode=10413&Desc=Transaction refused because of an invalid argument. See additional error messages for details.& Desc2=The totals of the cart item amounts do not match order amounts.")

My CART: 
Item: Mens Jackets 
Price: 14.99 
DESC: "SAMPLE" 
QTY: 1 
ITEM TOTAL: 14.99 
SHIPPING: 5.99 

CART TOTAL: 20.94 

我設置以下變量，我不知道我做錯了。

NVPCodec encoder = new NVPCodec(); 
         encoder["METHOD"] = "SetExpressCheckout"; 
         encoder["RETURNURL"] = returnURL; 
         encoder["CANCELURL"] = cancelURL; 
         encoder["BRANDNAME"] = "Mountain Warehouse Sample Application"; 
         encoder["PAYMENTREQUEST_0_PAYMENTACTION"] = "Sale"; 
         encoder["PAYMENTREQUEST_0_CURRENCYCODE"] = "GBP"; 

         // Get the Shopping Cart Products 
         int i = 0; 
         Decimal totalItemAmt = 0.00M; 
         string cartShippingAmt = ""; 
         foreach (BasketItem item in basket.Items) 
         { 
            if (item.OrderItemType == OrderItemType.Product) 
            { 
               encoder["L_PAYMENTREQUEST_0_NAME" + i] = item.Name.ToString(); 
               encoder["L_PAYMENTREQUEST_0_AMT" + i] = item.Price.ToString("0.00"); 
               encoder["L_PAYMENTREQUEST_0_QTY" + i] = item.Quantity.ToString(); 
               i++; 
               totalItemAmt += Convert.ToDecimal(item.Price.ToString("0.00")); 
            } 

            if (item.OrderItemType == OrderItemType.Shipping) 
            { 
               cartShippingAmt = item.Price.ToString("0.00"); 
            } 
         } 

         encoder["PAYMENTREQUEST_0_ITEMAMT"] = totalItemAmt.ToString(); 
         encoder["PAYMENTREQUEST_0_AMT"] = amt; 
         encoder["HANDLING_CART"] = cartShippingAmt; 

這裏是獲取發送到貝寶

METHOD=SetExpressCheckout& 
RETURNURL=http%3a%2f%2flocalhost%3a1234%2fCheckout%2fCheckoutReview.aspx& 
CANCELURL=http%3a%2f%2flocalhost%3a1234%2fCheckout%2fCheckoutCancel.aspx& 
BRANDNAME=Sample+Application& 
PAYMENTREQUEST_0_PAYMENTACTION=Sale& 
PAYMENTREQUEST_0_CURRENCYCODE=GBP& 
L_PAYMENTREQUEST_0_NAME0=MENS+JACKETS& 
L_PAYMENTREQUEST_0_AMT0=14.99& 
L_PAYMENTREQUEST_0_QTY0=1& 
PAYMENTREQUEST_0_ITEMAMT=14.99& 
HANDLING_CART=5.95& 
PAYMENTREQUEST_0_AMT=20.94 

我覺得我對整個車分配錯誤的變量運費查詢。

Answer 1

這裏有一些錯誤。

首先，您使用的一些請求參數不正確。 HANDLING_CART不是有效的請求參數。我認爲你要找的是HANDLINGAMT（實際上是PAYMENTREQUEST_0_HANDLINGAMT）。

在每次付款中，ITEMAMT + SHIPPINGAMT + HANDLINGAMT + TAXAMT的總和需要等於AMT。在你的情況，貝寶是忽略你發送無效參數，所以它最終看到下面...

PAYMENTREQUEST_0_ITEMAMT = 14.99 PAYMENTREQUEST_0_AMT = 20.94

這不是看到你的操作數量，因爲這一參數是因此，總數根據他們所看到的不匹配。您只需將HANDLING_CART更改爲PAYMENTREQUEST_0_HANDLINGAMT即可解決問題。

這裏有多個項目，其中包括一些額外的選項的工作SetExpressCheckout請求的樣本...
