我在Paypal沙箱中有三个帐户：两个商家和一个个人。我的所有Paypal账户都以美元作为默认货币。

在上面的代码中我使用欧元作为货币。

当我进行交易时，如果我从我的个人（买方）账户用欧元付款，那么我的买家账户就会扣除相应的金额（相当于从我的买方账户中扣除的美元金额）。这完全没问题，没有问题。

问题是我的商家或（卖家）帐户中没有添加任何金额。

我在Stack Overflow上发现了一篇文章：

如果交易的货币代码和卖家帐户不相符匹配，然后钱不会被卖给卖家帐户

我将欧元兑换成美元，（因为我的沙盒卖家测试帐户是美元），并发现在将其转换为美元后，我的钱就会被添加到我的卖家帐户中。

这只是沙箱的问题，还是它也适用于现场支付宝贝？

我有一个网站，买家可以支付英镑，欧元，新元，新元，澳元。

如果交易需要以特定货币执行，即根据卖家账户设置的货币，则无需使用不同的货币。

由于在SetExpressCheckOut中传递的currencyCode应与DoExpressCheckout匹配，并且因为我遇到问题，currencyCode需要与沙盒卖家帐户的相同，所以即使买家选择了GBP，我也必须将其发送到SetExpressCheckout作为卖家帐户的currencyCode。

Answer 1

您应该通过相关商家帐户的控制面板添加您希望接收付款的货币。

转到Profile - ＆gt; My Settings - ＆gt;财务信息选项卡和Currency Balances。从那里选择一种货币并将其添加到列表中。然后，您收到的付款将保留在相应的货币余额中，直到您将其转换为您想要的任何货币余额。

Answer 2

默认情况下，以您未持有的货币进行的交易将一直保留，直到您决定如何处理它们为止。如果您登录有问题的卖家帐户，您应该会看到您的历史记录中列出的交易。你应该能够接受它或者从那里否认它。

有两种解决方法：

正如Alderis所说，将欧元作为货币余额添加到卖家的帐户中。
让所有以您不会自动接受并转换为美元的货币进行的交易。为此，请登录卖家的帐户，点击个人资料，然后点击付款接收偏好设置（在销售偏好设置中）列），然后设置以我未持有的货币>阻止向我发送付款否，接受并将其转换为美元，然后点击保存< /强>
