我是PayPal express的新手，函数返回错误10413。客户看到这个账单：

1.Item   Price: 77€
2.Item 2 Price:79€

Subtotal: 128.93€ (without tax)
Shipping: 3.95€ (without tax)
TAX:      27.83€(Item's tax + shipping's tax)
Discount: -31.2€

Total to pay:   129.58€

在 CallShortcutExpressCheckout 我做这个字符串：

&PAYMENTREQUEST_0_AMT=129.58
&PAYMENTREQUEST_0_PAYMENTACTION=Sale
&RETURNURL=http://example.com/FinalizarPedido
&CANCELURL=http://example.com/DetalleCarrito
&PAYMENTREQUEST_0_CURRENCYCODE=EUR
&INVOICEID=63f958d2dc0c08ae6d71059ff90eae22
&L_PAYMENTREQUEST_0_NAME0=Item
&L_PAYMENTREQUEST_0_AMT0=77.00
&L_PAYMENTREQUEST_0_QTY0=1
&L_PAYMENTREQUEST_0_NAME1=Item 2
&L_PAYMENTREQUEST_0_AMT1=79.00
&L_PAYMENTREQUEST_0_QTY1=1
&PAYMENTREQUEST_0_AMT=129.58
&PAYMENTREQUEST_0_TAXAMT=27.83
&PAYMENTREQUEST_0_ITEMAMT=156
&PAYMENTREQUEST_0_SHIPPINGAMT=3.95
&PAYMENTREQUEST_0_SHIPDISCAMT=31.20
SetExpressCheckout

错误在哪里？也许我必须输入不含税的商品价格&L_PAYMENTREQUEST_0_AMT0？

我发现了问题，只需要先减号折扣金额

&PAYMENTREQUEST_0_SHIPDISCAMT=-31.20

谢谢大家。

10413 API 响应意味着 ItemTotal、ShippingTotal、HandlingTotal 和 TaxTotal 加起来不等于提交的 OrderTotal 的值。有关此计算的规则，请参阅 PayPal 集成指南。

只是从快速查看您提供的内容来看，您似乎没有正确添加总计。看起来 PAYMENTREQUEST_0_ITEMAMT=156 应该是 PAYMENTREQUEST_0_ITEMAMT=156.58。下面是我刚刚提交的请求，它通过了。
