我正在尝试从 PayPal 的 SOAP API 获取交易详细信息，但我遇到了来自 PayPal 的错误。它返回错误：

The transaction id is not valid

我知道这是一个有效的交易 ID，因为我能够使用 PayPal NVP API 获取交易详细信息，但可能我的 SOAP 请求格式不正确。我按照我可以在网上找到的 PayPal SOAP API 示例来构建 SOAP XML，但它们很薄。我正在使用 mac 的 PAW 程序向 PayPal 的 API 发送 SOAP 请求，但这个问题应该可以使用 HTTP 客户端重现。

我尝试使用 PayPal 的 REST API，但无法获取交易详情（例如姓名、电子邮件、支付金额、自定义字段）。我还尝试使用NVP（名称-值-对）API，我确实取回了交易详细信息，但它并没有为我提供交易的所有存储自定义字段。当我登录 PayPal 并查看单个交易时，我可以看到该交易的所有自定义字段，因此我知道它们正在被存储。

SOAP API 是我最后的希望。

这是我正在使用的 SOAP 信封请求：

我不确定我做错了什么，但也许有更多经验的人比我更容易发现错误。我回答了另一个用户关于 PayPal REST API 并从中获取交易详细信息的问题，但据我所知，没有办法做到Get customer details after transaction。如果您找到了使用 REST API 完成此操作的方法，请告诉我，因为我更愿意使用 REST 而不是 SOAP。

谢谢。

错误消息是一条红鲱鱼。PayPal 找不到任何 TransactionId，将空的 TransactionId 报告为无效。

TransactionId 元素属于urn:ebay:api:PayPalAPI命名空间。您的 XML 将其附加到urn:ebay:apis:eBLBaseComponents命名空间。您需要做的就是将 更改ebl:TransactionId为ns:TransactionId.

我会将此作为评论，但它充满了愚蠢的东西。以我的距离为代价，我可能会有所帮助。所以我的 vb.net 代码向贝宝发送了一个包含“notify_url”的表单。

            ' determining the URL to work with depending on whether sandbox or a real PayPal account should be used
            If strRealOrSand = "Sand" Then
                URL = "https://www.sandbox.paypal.com/cgi-bin/webscr"
                business = "x@xxx.com"  ' AppSettings("BusinessEmail")  (sandbox account business email)
            ElseIf strRealOrSand = "Real" Then
                URL = "https://www.paypal.com/cgi-bin/webscr"
                business = "xxx@xxx.com"    ' AppSettings("BusinessEmail")  (real pay pal account account business email)
            End If

notify_url = "http://www.xxxxx.com/accounts/done.aspx"  



    <form id="payForm" method="post" action="<%Response.Write (URL)%>" >
        <input type="hidden" name="cmd" value="<%Response.Write (cmd)%>" />
        <input type="hidden" name="business" value="<%Response.Write (business)%>" />
        <input type="hidden" name="item_name" value="<%Response.Write (item_name)%>" />
        <input type="hidden" name="amount" value="<%Response.Write (amount)%>" />
        <input type="hidden" name="no_shipping" value="<%Response.Write (no_shipping)%>" />
        <input type="hidden" name="return" value="<%Response.Write (return_url)%>" />
        <input type="hidden" name="rm" value="<%Response.Write (rm)%>" />
        <input type="hidden" name="notify_url" value="<%Response.Write (notify_url)%>" />
        <input type="hidden" name="cancel_return" value="<%Response.Write (cancel_url)%>" />
        <input type="hidden" name="currency_code" value="<%Response.Write (currency_code)%>" />
        <input type="hidden" name="custom" value="<%Response.Write (row_id)%>" />
    </form>

    <script type="text/javascript">
        document.forms["payForm"].submit ();
    </script>

</body>

然后在我的“notify_url”页面加载中，它会在交易完成后获取 PayPal 发回的内容。您会注意到有大量的调试电子邮件被发回给我。这是我做的。

我认为请求/响应如下：

提交的表格

URL = "https://www.paypal.com/cgi-bin/webscr"

在提交的“notify_url”中发回这个

Dim vWebRequest As System.Net.HttpWebRequest
            Dim vSSend As Boolean = False
            'vWebRequest = CType(System.Net.WebRequest.Create("https://www.sandbox.paypal.com/cgi-bin/webscr"), System.Net.HttpWebRequest)
            vWebRequest = CType(System.Net.WebRequest.Create("https://www.paypal.com/cgi-bin/webscr"), System.Net.HttpWebRequest)

当然有一个“PayPalFiddle”会很好哈哈
