paypal IPN获得买方交易ID

Question

我需要与交易相对应的买方交易ID,PayPal通过IPN通知我.我正在使用

$_POST['txn_id']

但是这会存储卖方的交易ID,而不是买方的交易ID.同时,买方无法访问卖方的交易ID.

我理解PayPal分配两个不同的交易ID,但卖方需要存储买方交易ID,以便能够与用户就特定交易进行通信.

当PayPal向我的IPN脚本发送通知时,任何人都知道如何接收(或搜索)买方交易ID？

我只收到以下数据:

Array

    [mc_gross] => 7.00
    [protection_eligibility] => Ineligible
    [payer_id] => F6912JHUIIHA

Answer 1

从paypal发回的变量列表来看，没有买家交易id。

另外一个选择：

通常，当您将订单信息发送到 PayPal 时，您可以包含发票/订单号，如果需要，买家可以通过您的发票号搜索他的历史记录（与他们通过交易 ID 搜索的方式相同）。当您将信息发送到贝宝时。
