从 PayPal SOAP API 获取交易详情（希望还有自定义字段）
Getting Transaction Details From PayPal SOAP API (hopefully custom fields as well)
我正在尝试从 PayPal 的 SOAP API 获取交易详细信息，但我 运行 进入 PayPal 的错误。它 returns 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，但也许我的 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，但使用 HTTP 客户端应该可以重现此问题。
我尝试使用 PayPal 的 REST API 但 there's no method to get transaction details (e.g. name, email, amount paid, custom fields) . I also tried to use the NVP (Name-Value-Pair) API 我确实取回了交易详细信息，但它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，因此我知道它们已被存储。
肥皂 API 是我最后的希望。

当然要有一个"PayPalFiddle"哈哈
错误消息是转移注意力。 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 ebl:TransactionId 更改为 ns:TransactionId。

cmd.ExecuteNonQuery()
'SEND ACCOUNT UPDATE AMOUNT TO DEVELOPER
sSend_Mail_From_done_aspx(intCreditsPurchased & " CREDITS ADDED TO ", sb.ToString)
cmd.Dispose()
conn.Close()
conn = Nothing
MySession.Credits = intCreditsPurchased
Catch ex As Exception
sSend_Mail_From_done_aspx("tblTransactions NOT UPDATED with Transaction Info", ex.ToString())
End Try
Else
sSend_Mail_From_done_aspx(Trim(vResponder).ToUpper, "TRANSACTION NOT VERIFIED")
End If
End Sub
我认为request/responses是下面这些：
已提交表格
URL = "https://www.paypal.com/cgi-bin/webscr"
在提交的"notify_url"里面发回这个
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)
当然要有一个"PayPalFiddle"哈哈
错误消息是转移注意力。 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 ebl:TransactionId 更改为 ns:TransactionId。
