【问题描述】：
我正在开发 NVP API 集成，整个支付流程运行正常。完成后我从 PayPal 收到的回复并未提供所有正确信息。
这是我发送 PayPal 的代码
&PAYMENTREQUEST_0_AMT=44.48
&PAYMENTREQUEST_0_ITEMAMT=40
&PAYMENTREQUEST_0_TAXAMT=4.48
&PAYMENTREQUEST_0_SHPPINGAMT=0
&PAYMENTREQUEST_0_INVNUM=5193f0cca7e70
&PAYMENTREQUEST_0_CURRENCYCODE=USD
&PAYMENTREQUEST_0_DESC=Test payment desc
&L_PAYMENTREQUEST_0_AMT0=40
&L_PAYMENTREQUEST_0_QTY0=1
&L_PAYMENTREQUEST_0_NAME0=Test item
&L_PAYMENTREQUEST_0_NUMBER0=5191cd62462fb
&L_PAYMENTREQUEST_0_DESC0=Test item desc
&L_PAYMENTREQUEST_0_SHPPINGAMT0=0.00
&L_PAYMENTREQUEST_0_TAXAMT0=4.48
&RETURNURL=[REMOVED]
&CANCELURL=[REMOVED]
&BRANDNAME=Some Con 2014
&CUSTOMERSERVICENUMBER=000-000-0000
订单通过并处理了正确的付款，但是返回的信息缺少税务信息。

为什么 PAYMENTINFO_0_TAXAMT 在 4.48 时返回 0？
我还遇到一个问题，即从 PayPal 购买时发送的电子邮件没有列出所购买的商品，而只是列出了总金额。注意描述不是商品描述而是整体订单描述。
