我试图从PayPal的SOAP API获取交易详细信息，但我遇到了PayPal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，因为我可以使用PayPal NVP API获取交易详细信息，但可能我的SOAP请求格式不正确。我遵循了PayPal SOAP API示例，我可以在web上找到这些示例来构建SOAP XML，但它们都很瘦。我使用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，但无法获取交易详细信息（例如姓名、电子邮件、支付金额、自定义字段）。我还试着使用NVP（Name-Value-Pair）API，我确实得到了交易的详细信息，但它并没有为交易提供所有存储的自定义字段。当我登录PayPal并查看一笔交易时，我可以看到该交易的所有自定义字段，所以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，但也许有经验的人比我更容易发现错误。我回答了另一位用户关于PayPal REST API的问题，并从中获取交易详细信息，但据我所知，没有办法在交易后获取客户详细信息。如果您已经找到了使用REST API实现这一点的方法，请让我知道，因为我更愿意使用REST而不是SOAP。
谢谢。
错误消息只是转移注意力。PayPal找不到任何TransactionId，报告空的TransactionId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。您所需要做的就是将ebl:TransactionId更改为ns:TransactionId。

请在PayPal知识库中查看此示例。
我本想把它作为一个评论，但它充满了粘性。以牺牲远离为代价，我可能会得到一些帮助。因此，我的vb.net代码向paypal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，它会在交易完成后收到PayPal发回的信息。你会注意到有大量的调试电子邮件被发送回我。这是我做的

我认为请求/响应如下：
提交的表单

在提交的"notify_url"中发送回此
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
