Getting Transaction Details From PayPal SOAP API (hopefully custom fields as well)

I'm trying to get transaction details from PayPal's SOAP API but I'm running into into error from PayPal. It returns the error:

The transaction id is not valid

I know it's a valid transaction ID since I'm I'm able to get transaction details using the PayPal NVP API but maybe I have the SOAP request formatted incorrectly. I followed the PayPal SOAP API examples I can find across the web to construct the SOAP XML but they are slim. I'm using mac's PAW program to send a SOAP request to PayPal's API but this problem should be reproducible using an HTTP client.

I tried to use PayPal's REST API but 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 and I do get back the transaction details but it doesn't give me all of the stored custom fields for a transaction. When I log in to PayPal, and view a single transaction, I can see all of the custom fields for that transaction, so I know they're being stored.

The SOAP API is my last hope.

Here's the SOAP envelope request I'm using:

 <?xml version="1.0" encoding="UTF-8"?>
 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="urn:ebay:api:PayPalAPI" xmlns:ebl="urn:ebay:apis:eBLBaseComponents" xmlns:cc="urn:ebay:apis:CoreComponentTypes" xmlns:ed="urn:ebay:apis:EnhancedDataTypes">

Here's the response I receive from the PayPal SOAP API:

        </GetTransactionDetailsResponse>
      </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>

I'm not sure what I'm doing wrong but maybe someone with more experience can spot the error easier than I can. I responded to another user's question about the PayPal REST API and getting transaction details from that but as far as I know, there's no way to do that Get customer details after transaction . If you have found a way to accomplish this with the REST API, let me know cause I would much rather use REST than SOAP.

Thanks.

The error message is a red herring. PayPal can't find any TransactionId, reporting the empty TransactionId as invalid.

The TransactionId element belongs to the urn:ebay:api:PayPalAPI namespace. Your XML attaches it to the urn:ebay:apis:eBLBaseComponents namespace. All you need to do is change the ebl:TransactionId to ns:TransactionId.

 <?xml version="1.0" encoding="UTF-8"?>
  <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="urn:ebay:api:PayPalAPI" xmlns:ebl="urn:ebay:apis:eBLBaseComponents" xmlns:cc="urn:ebay:apis:CoreComponentTypes" xmlns:ed="urn:ebay:apis:EnhancedDataTypes">
  <soapenv:Header>
       <ns:RequesterCredentials>
            <ebl:Credentials>
                 <ebl:Username>soap_api_username_here</ebl:Username>
                 <ebl:Password>soap_api_password_here</ebl:Password>
                 <ebl:Signature>soap_api_signature_here</ebl:Signature>
            </ebl:Credentials>
       </ns:RequesterCredentials>
  </soapenv:Header>
  <soapenv:Body>
      <ns:GetTransactionDetailsReq>
           <ns:GetTransactionDetailsRequest>
                <ebl:Version>204.0</ebl:Version>
                <ns:TransactionID>8FX18476NR449891W</ns:TransactionID>
           </ns:GetTransactionDetailsRequest>
      </ns:GetTransactionDetailsReq>
 </soapenv:Body>

I would have put this as a comment but it is pretty full of goobly gook. At the expense of being way off I might be of some help maybe. So my vb.net code sends a form to paypal which includes "notify_url".

            ' 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 = "[email protected]"  ' AppSettings("BusinessEmail")  (sandbox account business email)
            ElseIf strRealOrSand = "Real" Then
                URL = "https://www.paypal.com/cgi-bin/webscr"
                business = "[email protected]"    ' 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>

Then in my "notify_url" page load it gets what PayPal sends back after transaction completes. You'll notice there is a ton of debug emails being sent back to me. This was my doing.

            sSend_Mail_From_done_aspx(Trim(vResponder).ToUpper, "TRANSACTION NOT VERIFIED")

        End If
    End Sub

I think the request/responses are these below:

submitted form

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

sends back to this inside the "notify_url" that is submitted

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)

Sure would be nice to have a "PayPalFiddle" haha
