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']

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

据我所知，PayPal分配了两个不同的交易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沟通。

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发回的变量列表的外观来看，没有买方交易ID。

另一种选择：

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，买方可以按您的发票号码搜索其历史记录（与按交易ID搜索的方式相同）当您将信息发送到PayPal时，请将其包括在内。

Answer 2

您可以使用GetTransactionDetails API并传入买方的交易ID。

示例API调用将是：
METHOD = GetTransactionDetails＆安培;
TRANSACTIONID =买家交易ID＆amp;
