Paypal 快速结账 : how should I check if the transaction is done and money is transferred?

Question

我在客户端有 PayPal 快速结账，在使用支付 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。

state is approved 但 transactions[0].related_resources[0].sale.state === pending

那么我应该如何检查交易是否完成并且钱是否转给卖家以激活他/她支付的服务？

从回调中，我有买家电子邮件、payerId、paymentID、paymentToken，所以也许我需要一些其他端点？

Answer 1

这就是我最终发现的:

The "approved" state just means the buyer logged into their account and approved the payment. You still need to execute the payment request, which once you do check the "state" shown in the "related_resources" section and it should say "completed", which indicates the transaction amount has been captured. The "id" shown below is the transaction identifier.
