Paypal 商品折扣至免费，运费仍需支付

Question

我目前正在网站上设置 Paypal，作为客户的替代付款方式。总的来说，它运行良好；我可以下订单，它会进入 Paypal 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，一切仍然正常，无需担心。

当用户对整个订单价值应用折扣时（即订单价格为 20 英镑，他们有 20 英镑折扣的折扣代码），我收到错误“商品总计无效”。从贝宝回来。发送的成本为 0 英镑，发送的运费为 5 英镑。

首先，我发送的字段是否有问题，如果有，问题出在哪里？ :) 如果您需要更多信息，请随时询问。

您不能向 PayPal 发送空金额或零金额。 0.01 美元是您可以接受的最低价格。

您可以尝试通过从运费中提取一美分并将其添加到总额中来解决此问题，或者如果商品费用为零，则交换运费和商品费用。
