与错误代码集成的购物车范围内的运费：10413

Question

我正在尝试通过 sandbox 为我的网站集成 payapl。

我可以将多个项目发送到 paypal，而且效果很好。但是我想设置 CART-WIDE 运费并将其发送到 paypal。

我收到错误代码：

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

我正在设置以下变量，但我不知道我做错了什么。

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;

这是发送到 paypal

L_PAYMENTREQUEST_0_QTY0=1&
PAYMENTREQUEST_0_ITEMAMT=14.99&
HANDLING_CART=5.95&
PAYMENTREQUEST_0_AMT=20.94

我认为我为整个购物车分配了错误的可变运费。

Answer 1

这里有一些问题。

首先，您使用的某些请求参数不正确。 HANDLING_CART 不是有效的请求参数。我认为您正在寻找的是 HANDLINGAMT（实际上是 PAYMENTREQUEST_0_HANDLINGAMT）。

每次付款时，ITEMAMT + SHIPPINGAMT + HANDLINGAMT + TAXAMT 的总和需要等于 AMT。在您的情况下，PayPal 忽略了您发送的无效参数，因此最终会看到以下内容...

PAYMENTREQUEST_0_ITEMAMT = 14.99 PAYMENTREQUEST_0_AMT = 20.94

它没有看到您的处理金额，因为该参数无效，因此，总数与他们看到的不匹配。您只需将 HANDLING_CART 更改为 PAYMENTREQUEST_0_HANDLINGAMT 即可解决您的问题。

这是一个有效的 SetExpressCheckout 请求示例，其中包含多个项目和一些附加选项...
