【问题描述】：

我正在向贝宝请求的数据 (SetExpressCheckout)

[METHOD] => SetExpressCheckout

[ENDPOINT] => https://api-3t.sandbox.paypal.com/nvp
[USER] => ***
[PWD] => ***
[SIGNATURE] => ***
[VERSION] => 84.0

[L_ITEMCATEGORY0] => Physical
[L_QTY0] => 4
[L_AMT0] => 2.20
[L_DESC0] => ZajÄ…czek 1
[L_NAME0] => ZajÄ…czek 1
[L_CURRENCYCODE0] => GBP
[L_ITEMCATEGORY1] => Physical

[L_AMT1] => 3.20
[L_DESC1] => ZajÄ…czek 2

但我总是遇到错误：

[L_LONGMESSAGE0] => The totals of the cart item amounts do not match order amounts.

我在向请求中添加运费时做错了什么？？

【问题讨论】：

您的问题解决了吗？

【参考方案1】：

[PAYMENTREQUEST_PAYMENTACTION] => Sale
[PAYMENTREQUEST_ITEMAMT] => 12
[PAYMENTREQUEST_AMT] => 14.21

应该是：

[PAYMENTREQUEST_0_PAYMENTACTION] => Sale
[PAYMENTREQUEST_0_ITEMAMT] => 12
[PAYMENTREQUEST_0_AMT] => 14.21

此外，您的金额不会相加。您设置的最大值为 14.21，但所有值加起来只有 7.41

L_AMTm（实际上应该是 L_PAYMENTREQUEST_0_AMTm）是特定于项目的。 PAYMENTREQUEST_0_ITEMAMT 是所有项目的小计 PAYMENTREQUEST_0_AMT 应该是所有内容的总和。

例如

[SOLUTIONTYPE] => Sole
[LANDINGPAGE] => Billing
[L_PAYMENTREQUEST_0_ITEMCATEGORY0] => Physical
[L_PAYMENTREQUEST_0_QTY0] => 4
[L_PAYMENTREQUEST_0_AMT0] => 2.20
[L_PAYMENTREQUEST_0_DESC0] => ZajÄ…czek 1
[L_PAYMENTREQUEST_0_NAME0] => ZajÄ…czek 1
[L_PAYMENTREQUEST_0_CURRENCYCODE0] => GBP
[L_PAYMENTREQUEST_0_ITEMCATEGORY1] => Physical
[L_PAYMENTREQUEST_0_QTY1] => 1
[L_PAYMENTREQUEST_0_AMT1] => 3.20
[L_PAYMENTREQUEST_0_DESC1] => ZajÄ…czek 2
[L_PAYMENTREQUEST_0_NAME1] => ZajÄ…czek 2
[L_PAYMENTREQUEST_0_CURRENCYCODE1] => GBP
[PAYMENTREQUEST_0_PAYMENTACTION] => Sale
[PAYMENTREQUEST_0_SHIPPINGAMT] => 2.21
[PAYMENTREQUEST_0_ITEMAMT] => 5.40
[PAYMENTREQUEST_0_AMT] => 7.61

或者official PayPal example：

&L_PAYMENTREQUEST_0_NAME0=10% Decaf Kona Blend Coffee  
&L_PAYMENTREQUEST_0_NUMBER0=623083  
&L_PAYMENTREQUEST_0_DESC0=Size: 8.8-oz 
&L_PAYMENTREQUEST_0_AMT0=9.95  
&L_PAYMENTREQUEST_0_QTY0=2  
&L_PAYMENTREQUEST_0_NAME1=Coffee Filter bags  
&L_PAYMENTREQUEST_0_NUMBER1=623084  
&L_PAYMENTREQUEST_0_DESC1=Size: Two 24-piece boxes  
&L_PAYMENTREQUEST_0_AMT1=39.70  
&L_PAYMENTREQUEST_0_QTY1=2  
&PAYMENTREQUEST_0_ITEMAMT=99.30  
&PAYMENTREQUEST_0_TAXAMT=2.58  
&PAYMENTREQUEST_0_SHIPPINGAMT=3.00  
&PAYMENTREQUEST_0_HANDLINGAMT=2.99  
&PAYMENTREQUEST_0_SHIPDISCAMT=-3.00  
&PAYMENTREQUEST_0_INSURANCEAMT=1.00  
&PAYMENTREQUEST_0_AMT=105.87  
&PAYMENTREQUEST_0_CURRENCYCODE=USD  

【讨论】：

[L_SHORTMESSAGE0] => 由于参数无效，交易被拒绝。有关详细信息，请参阅其他错误消息。 [L_LONGMESSAGE0] => 购物车商品总金额与订单金额不符。

@PayPal_Robert 如何使用折扣？

我已回复您的电子邮件。基本上，您会传递一个负的订单项金额并确保总金额匹配。 IE。 L_PAYMENTREQUEST_0_AMT0=-2.00 获得 2 美元的“折扣”。
