我试图在一个订单中设置多个货币代码

我将此json发送到PayPal API，并随机分发了两个货币代码：欧元和美元

我在PayPal文档和Google上搜索过，但不清楚是否可以在一个订单中设置两种或更多的货币

插入的货币（欧元和美元）均在我的PayPal设置中获得批准，以下是PayPal常见问题解答：

如果我需要在一次交易中设置多个产品和两种货币，我不能这样做吗？我是否将订单分为两个顺序，为每个顺序应用单一货币代码？

不支持多个不同的货币代码值。整个订单请求必须具有相同的货币代码。

谢谢@Preston，您仅从PayPal response复制了此消息。如果我需要在一个事务中设置多个不同币种的产品，我不能这样做吗？我是否在两个订单中执行单独的订单，为每个订单应用单一货币代码？如果必须使用单独的货币，则交易必须是单独的。
