PayPal API v2，获取交易ID

Question

我想知道如何从PayPal API v2获取交易ID。

我已经通过PayPal API v2（https://developer.paypal.com/docs/api/orders/v2/）创建了一个订单，并成功捕获了它。订单状态为“已完成”，并且该订单已出现在我的PayPal沙箱帐户中的“活动”中。现在，我想获取捕获交易的交易ID（参见图片），但我无法获取它。

我可以通过PayPal API获取订单的详细信息，但是只获取了订单ID和捕获ID。 API响应中缺少在图像上标记的交易ID。我需要怎么做才能获得交易ID？非常感谢。

Answer 1

有两个交易ID，一个用于卖方，一个用于买方。作为API调用者，您只能看到卖方交易ID（捕获ID），而看不到买方。

您出于任何原因需要显示买方的transaction_id？
