我与paypal进行了整合。我正在使用REST API for java。目前，我的待付款有问题。当我向沙箱环境查找付款（https://api.paypal.com/v1/payments/payment/ {paymentId}）以检查付款状态时，回复会有所不同。 当我批准作为卖家付款时，付款处于状态
批准
并且销售处于状态
完成

同样，当我拒绝交易时，Sanbox也会工作。一旦付款状态失败并且销售状态被撤销，另一个时间待决并保留。
我的问题是什么时候可以100％确定交易完成或失败？ 我应该检查付款状态还是销售状态？ 也许这个问题只与沙箱有关而不是生产。
PS。此代码仅为示例，请勿对其进行分析。

您应该确保即使销售状态显示已完成，付款也已获得批准。即使在销售状态显示完成后，也可能存在与特定买方帐户相关的某些内容，这使得付款处于待处理状态。在运送产品之前，您应确保付款已获得批准。
