Question

我正在尝试在我的网站上进行销售，客户可以免费获得商品，他们只需支付运费。

然而，似乎PayPal似乎没有应对此问题：我收到错误10413: The totals of the cart item amounts do not match order amounts.

我发送给PayPal的请求是：

L_PAYMENTREQUEST_0_AMT0: "0.00"
L_PAYMENTREQUEST_0_DESC0: "Pink+Bare+Cub+nappy+and+cream+wetbag"
L_PAYMENTREQUEST_0_NAME0: "Facebook+Nappy+Giveaway"
L_PAYMENTREQUEST_0_QTY0: "1"
METHOD: "SetExpressCheckout"
PAYMENTREQUEST_0_AMT: "7.50"
PAYMENTREQUEST_0_CURRENCYCODE: "AUD"
PAYMENTREQUEST_0_CUSTOM: "agtzfmJhYnktYmFyZXISCxILY2FydEludm9pY2UYq1EM"
PAYMENTREQUEST_0_ITEMAMT: "0.00"
PAYMENTREQUEST_0_PAYMENTACTION: "Sale"
PAYMENTREQUEST_0_SHIPPINGAMT: "7.50"
VERSION: "63.0"

（有些字段被简化为简化）

我收到的回复：

ACK: "Failure"
BUILD: "3242673"
CORRELATIONID: "c8b284c8a04fa"
L_ERRORCODE0: "10413"
L_LONGMESSAGE0: "The%20totals%20of%20the%20cart%20item%20amounts%20do%20not%20match%20order%20amounts%2e"

任何想法如何解决这个问题？

Answer 1

不幸的是，你不能拥有零价值物品。

一个解决方案是创建一个名为Free Pink Bare Cub nappy and cream wetbag + Shipping的项目并将其值设置为运费金额。并使用这些说明绝对清楚，买家只需支付运费。

另一个选项是为商品指定0.01的值，然后使用PAYMENTREQUEST_0_SHIPDISCAMT字段

为买家提供0.01折优惠

编辑：虽然我没有根据您的评论亲自测试一个免费项目和一个付费项目，但解决方法很简单。只需拥有您的免费物品，然后创建第二个项目，名为运输和处理

Answer 2

在计算最终总金额时，您应该包含以下值。

PAYMENTREQUEST_0_ITEMAMT - this is order total without sipping, tax etc.
PAYMENTREQUEST_0_TAXAMT
PAYMENTREQUEST_0_SHIPPINGAMT
PAYMENTREQUEST_0_INSURANCEAMT
PAYMENTREQUEST_0_HANDLINGAMT
PAYMENTREQUEST_0_AMT - this is order total + tax, shipping etc.

当商品添加到$ 0时，Paypal SetExpressCheckout错误10413
