Question

如果我的INITAMT请求等于经常性付款金额，则可以。

但是，如果我尝试对不同的INITAMT（以及不同的TAX）收费，我会收到此错误：

Tax calculation mismatch. The tax amount for the regular non-trial billing period is different than the sum of the tax for each item in the cart.

我的实际要求：

我的首付款为4.84€，含增值税0.84€。

下个月，账单金额应为25.09欧元（包括6.09欧元增值税）。

我发送的请求基本上是这样的：

Method: CreateRecurringPaymentsProfile
"CURRENCYCODE":"EUR",
"INITAMT":4.84,
"TAXAMT":0.84,
"DESC":"Subscription",
"BILLINGPERIOD":"Month",
"BILLINGFREQUENCY":1,

我想使用 INITAMT 值进行此操作，以便用户可以在Paypal私有区域中看到两个相关的购买（即：带有初始付款的订阅）。< / p>

否则我将不得不为初始付款单独执行DoExpressCheckout。

发生的事情是你不能（我相信）为初始金额设定税额。

TAXAMT用于定期付款，而不是初始金额。

您的陈述是“收取29欧元，税率为0.84欧元”。

但是，您的项目清单显示税额应为6.09€

将您的TAXAMT更改为6.09€，应该没问题。

定期付款：如何指定不同于后续周期的初始付款TAX值？
