我在客户端有 PayPal 快速结帐，在使用付款 ID 触发回调后，我想在 NodeJS 端检查该 ID。我使用 JS SDK 调用 RESTfull API：
https://developer.paypal.com/docs/api/payments/v1/#payment_get
我在下面得到这样的对象。
状态已获批准但transactions[0].related_resources[0].sale.state===待定
那么我应该如何检查交易是否完成并且钱是否转移给了卖家以激活他/她支付的服务？
从回调中，我有买家电子邮件、payerId、paymentID、paymentToken，所以也许我需要其他一些端点？
