我们正在使用 MassPay API 向我们的用户发送付款。我们的系统的工作方式是每个 MassPay 批次仅包含一次付款。

我们的问题是尚不完全清楚 MassPay IPN 状态是如何工作的。

PayPal 文档说有 3 种类型的 IPN - 失败、已处理和已完成。

我不明白 payment_status 和 status1 的哪些状态组合是可能的：

  1. IPN 可以返回 (payment_status = DENIED和status1 = Completed) 吗？
  2. IPN 是否会带有status1 = FAILED或BLOCKED始终带有 a payment_status = DENIED，反之亦然？
  3. ( ) 是否payment_status = PROCESSED and status1 = COMPLETED总是出现在带有 ( payment_status = COMPLETED and status1 = COMPLETED) 的 IPN 之前？如果是，仅检查 ( payment_status = COMPLETED and status1 = COMPLETED) 以在我们的系统上将支付标记为“成功”就足够了吗？
  4. IPNstatus1 = REVERSED or RETURNED总是有payment_status = COMPLETED吗？
  5. IPNstatus1 = PENDING总是有一个payment_status = PROCESSED?

更具体地说，这将有助于了解 payment_status 和 status1 组合中的哪一个甚至是可能的，以及每个可能的状态对的含义是什么？

见附表1

这是文本中的表格：
