paypal - PAYMENT.SALE.COMPLETED webhook 事件中的 PayPal 订阅 ID 和交易 ID 在哪里？如何获取他们的详细信息？

Question

我正在使用带有 php 的 PayPal 订阅 API。
到目前为止，我知道成功付款后会触发 PAYMENT.SALE.COMPLETED 事件。但该对象只包含一个计费协议(protocol) ID，似乎与订阅无关。如何获得有关客户和付款的更多详细信息？

Answer 1

    "billing_agreement_id": "I-8XRLDA4MNEW3",

那就是您订阅的 ID。

    "id": "1P642136UK709905M",

那就是您的 PayPal 交易/销售/捕获 ID。

    "links": [
       {
           "method": "GET",
           "rel": "self",
           "href": "https://api.sandbox.paypal.com/v1/payments/sale/1P642136UK709905M"
       },
       {

有如何获取有关销售的详细信息(v2/payments/captures API 也可能有效，不确定)
