Paypal 贝宝回应漏税

我正在进行NVP API集成，整个支付过程正常。我在完成后从PayPal得到的回复并没有提供所有正确的信息

[TOKEN] => EC-1KS56755YX305151R

[PAYMENTINFO_0_ORDERTIME] => 2013-05-15T20:48:41Z
[PAYMENTINFO_0_AMT] => 44.48
[PAYMENTINFO_0_FEEAMT] => 1.59
[PAYMENTINFO_0_TAXAMT] => 0.00
[PAYMENTINFO_0_CURRENCYCODE] => USD
[PAYMENTINFO_0_PAYMENTSTATUS] => Completed

[PAYMENTINFO_0_SECUREMERCHANTACCOUNTID] => 3JTQYBPNDRWES
[PAYMENTINFO_0_ERRORCODE] => 0
[PAYMENTINFO_0_ACK] => Success

这是我发送给贝宝的代码

&PAYMENTREQUEST_0_AMT=44.48
&PAYMENTREQUEST_0_ITEMAMT=40
&PAYMENTREQUEST_0_TAXAMT=4.48
&PAYMENTREQUEST_0_SHPPINGAMT=0

订单通过并处理了适当的付款，但是返回的信息缺少税务信息

为什么PAYMENTINFO\u 0\u Taxam在4.48时返回0

我也有一个问题，即从贝宝购买时发送的电子邮件没有列出购买的物品，只有一个总金额。注意说明不是项目说明，而是整个订单说明

-----------------------------------
Purchase Details
-----------------------------------

Description: Test payment desc
Unit price: $44.48 USD
Qty: 1
Amount: $44.48 USD


Subtotal: $44.48 USD

由于未在DoExpressCheckoutPayment API调用中传递该税，因此未显示该税。我检查了日志，只显示您在setexpresscheckoutpayment API调用中传递了它，而没有在DoExpressCheckoutPayment API调用中传递它。如果您希望退货，则需要在Do EC电话中传递。这也是你描述的情况。它不会在Do EC呼叫中被忽略

更新了DoExpressCheckoutPayment API调用，现在一切都正常工作。谢谢你的帮助。
