PayPal 沙盒 API 不允许买家登录

Question

我正在开发移动应用程序的 android 工作室。 我有一个支付功能，我集成了 PayPal 沙箱，当用户点击查看 PayPal 页面时出现。 然而，当任何买家尝试使用出现的页面登录时，它“用户名/密码错误。请重试”虽然我确信它是正确的并尝试了多个帐户，其中一个拥有有效的真实信用卡但相同的 output。 我想知道为什么会这样？ 请有人尽快帮助我。

这是用户尝试登录时出现的内容： PayPal 错误消息的屏幕截图

提供了与支付部分相关的三个 java 类：

Answer 1

In order to log into a PayPal Sandbox page, you must use a PayPal Sandbox ( www.sandbox.paypal.com ) account, not a live ( www.paypal.com ) account.

You can create as many PayPal Sandbox accounts as you need within https://www.paypal.com/signin?returnUri=https%3A%2F%2Fdeveloper.paypal.com%2Fdeveloper%2Faccounts

他们的 email 标识符是虚构的，可以是以前未在沙盒中使用的任何内容。 没有真正的电子邮件发送到这些地址； 相反，在 developer.paypal.com 的左侧有一个通知选项卡
