我试图从PayPal的SOAP API获取交易详情，但我遇到了来自PayPal的错误。它返回错误：
The transaction id is not valid
我知道它是一个有效的交易ID，因为我能够使用PayPal NVP API获取交易详情，但可能我的SOAP请求格式不正确。我遵循了可以在Web上找到的PayPal SOAP API示例来构建SOAP XML，但它们很小。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there's no method to get transaction details（例如姓名，电子邮件，付款金额，自定义字段）。我还尝试使用NVP (Name-Value-Pair) API，我确实收到了交易详情，但它没有给我所有存储的交易自定义字段。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，因此我知道它们已被存储。
SOAP API是我最后的希望。
这是我使用的SOAP信封请求：

我不确定我做错了什么，但也许有经验丰富的人可以比我更容易发现错误。我回答了另一个用户关于PayPal REST API的问题，并从中获取了交易详情，但据我所知，没有办法做到Get customer details after transaction。如果您已经找到了使用REST API实现此目的的方法，请告诉我因为我宁愿使用REST而不是SOAP。
感谢。

错误消息是红鲱鱼。 PayPal无法找到任何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ebl:TransactionId更改为ns:TransactionId。

我会把它作为评论，但它充满了goobly gook。以牺牲方式为代价，我可能会有所帮助。 所以我的vb.net代码向paypal发送一个表单，其中包括＆＃34; notify_url＆＃34;。
' 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＆＃34; notify_url＆＃34;页面加载它获取PayPal在事务完成后发回的内容。您会注意到有大量的调试电子邮件被发回给我。这是我的行为。
