Paypal项目免费折扣，运费仍然支付

Question

我现在正在网站上设置Paypal作为客户的替代付款方式。 一般来说，它工作正常; 我可以下订单，然后通过Paypal的网站，显示正确的信息，一切都很好。 当用户对订单应用折扣时，事情仍然正常，不用担心。

当用户对完整订单价值应用折扣时（即订单为20英镑，他们有20英镑的折扣代码）我收到错误“商品总数无效”。 从Paypal回来。 发送的费用为0英镑，发送的费用为5英镑。

首先，我发送的字段是否有任何问题，如果是，那有什么不对？ :)如果您需要更多信息，请随时询问。

干杯。

您不能向PayPal发送空或零金额。 $ 0.01是你可以去的最低价。

您可以尝试解决这个问题，从运费中扣除一分钱并将其添加到总额中，或者如果物品费用为零则交换运费和物品费用。
