asp.net - DoDirectPayment : This transaction cannot be processed due to an invalid merchant configuration

Question

我是一名商家，想要向访问我网站的客户收费。

我正在调用 DoDirectPayment API，总是收费一次，从不重复计费。

Paypal 正确验证信用卡，当卡信息不正确时给出正确的错误消息，但当它正确并且是时候向客户收费时，它说:

This transaction cannot be processed due to an invalid merchant configuration.

我不明白为什么我在使用 DoDirectPayment API 时会收到此错误消息。

一切似乎都指向“结算协议(protocol)”。这是我必须在 Paypal 中配置的东西吗？

我对另一个 paypal 帐户使用相同的代码并且工作正常。好像我在 Paypal 中缺少配置。

您正在尝试处理信用卡付款，但您的 PayPal 帐户未启用，这就是您从 PayPal 的 DoDirectPayment API 收到“无效商户配置”错误响应的原因。

即使您在问题的标题中提到了“PayPal Express Checkout”，但如果出现此错误，您没有使用 Express Checkout 产品。

如果您所在的国家/地区(美国、英国、加拿大)提供 PayPal Website Payments Pro，您需要注册。

或者，使用 PayPal Express Checkout，它在(几乎)所有国家/地区都可用 PayPal 本身可用并且不需要月费。
