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

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.

但是,PayPal似乎并没有应对这个问题:我收到了错误 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"

(一些字段简化为简洁)

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"

知道如何解决这个问题吗？

Answer 1

不幸的是,你不能拥有零价值物品.

一种解决方案是调用一个项目Free Pink Bare Cub nappy and cream wetbag + Shipping 并将其值设置为出货量.并使用笔记绝对清楚买家只支付运费.

另一种选择是为物品指定0.01的值,然后使用该PAYMENTREQUEST_0_SHIPDISCAMT字段为买家提供0.01折扣,以抵消此

编辑:虽然我没有亲自测试一个免费项目和一个付费项目,根据您的评论,然后解决方法很容易.只需拥有您的免费物品,然后创建第二个名为" 运输和处理"的项目
