Required Fields for DPM using ASP.NET

I have been receiving the following error when attempting to post using DPM and ASP.NET:


(13) The merchant login ID or password is invalid or the account is inactive.


I am currently including the following fields:



























I am posting to the following URL using a developer account:


The account is in LIVE MODE. Are there any other fields I should or need to include, or any settings I should check or set? I can't figure out what the problem could be, or what steps I should take next to try to get everything working. Any help would be appreciated. Thanks.


The min fields for DPM (is form the documentation - section JAVA)

<form id='secure_redirect_form_id' action='' method='POST'>
<input type='text' class='text' id='x_card_num' name='x_card_num' size='20' maxlength='16' />
<input type='text' class='text' id='x_exp_date' name='x_exp_date' size='6' maxlength='6'/>
<input type='hidden' name='x_invoice_num' value='<%=System.currentTimeMillis()%>' />
<input type='hidden' name='x_relay_url' value='<%=relayResponseUrl%>' />
<input type='hidden' name='x_login' value='<%=apiLoginId%>' />
<input type='hidden' name='x_fp_sequence' value='<%=x_fp_sequence%>' />
<input type='hidden' name='x_fp_timestamp' value='<%=x_fp_timestamp%>' />
<input type='hidden' name='x_fp_hash' value='<%=x_fp_hash%>' />
<input type='hidden' name='x_version' value='3.1' />
<input type='hidden' name='x_method' value='CC' />
<input type='hidden' name='x_type' value='AUTH_CAPTURE' />
<input type='hidden' name='x_amount' value='<%=amount%>' />
<input type='hidden' name='x_test_request' value='FALSE' />
<input type='hidden' name='notes' value='extra hot please' />
<input type='submit' name='buy_button' value='BUY' />

 And you do NOT pass the x_tran_key


Did you look at the page source when you run the web page on the browser? to make sure everything is pass correctly?


I have included all the fields you mention, and removed the x_tran_key field, but still same error. I have also viewed the page source and it is what I expect, but still not success. Any other ideas? Thanks.

If and only if this is a test account, post the web broswer page source here.

Here is the page source from the page:


The form tag is:


<form name="aspnetForm" method="post" action="" id="aspnetForm" onsubmit="mckeepottery_com.MPWebServices.GenerateTimestamp(function(value){document.getElementById('x_fp_timestamp').value=value;});mckeepottery_com.MPWebServices.GenerateFingerprint('35LF5Mx3ryh4E52G','XXXXXXXXXXX',126.0000,'43',document.getElementById('x_fp_timestamp').value,function(value){window.setTimeout('document.getElementById('x_fp_hash').value=value;',1000);});">


The input fields are:


<input id="x_card_num" type="hidden" value="4007000000027"/><input id="x_exp_date" type="hidden" value="1212"/><input id="x_card_code" type="hidden" value=""/><input id="x_amount" type="hidden" value="126.00"/><input id="x_tax" type="hidden" value="6.00"/><input id="x_first_name" type="hidden" value="Nathan"/><input id="x_last_name" type="hidden" value="Sokalski"/><input id="x_address" type="hidden" value="1217 Maryland Avenue"/><input id="x_city" type="hidden" value="Allentown"/><input id="x_state" type="hidden" value="PA"/><input id="x_zip" type="hidden" value="18103"/><input id="x_ship_to_first_name" type="hidden" value="Nathan"/><input id="x_ship_to_last_name" type="hidden" value="Sokalski"/><input id="x_ship_to_address" type="hidden" value="1217 Maryland Avenue"/><input id="x_ship_to_city" type="hidden" value="Allentown"/><input id="x_ship_to_state" type="hidden" value="PA"/><input id="x_ship_to_zip" type="hidden" value="18103"/><input id="x_login" type="hidden" value="XXXXXXXXXXX"/><input id="x_fp_sequence" type="hidden" value="43"/><input id="x_test_request" type="hidden" value="TRUE"/><input id="x_fp_timestamp" type="hidden"/><input id="x_fp_hash" type="hidden"/><input id="x_relay_url" type="hidden" value=""/><input id="x_relay_response" type="hidden" value="TRUE"/><input id="x_version" type="hidden" value="3.1"/><input id="x_method" type="hidden" value="CC"/><input id="x_type" type="hidden" value="AUTH_CAPTURE"/>


You will notice that the form tag uses two WebMethods to set the x_fp_timestamp and x_fp_hash fields so that the timestamp is at the time it is submitted. Here is the codebehind code I used for the WebMethods:


Imports System.Web.Services

<ScriptService()> Public Class MPWebServices : Inherits System.Web.Services.WebService

<WebMethod()> Public Function GenerateTimestamp() As String

   Return AuthorizeNet.Crypto.GenerateTimestamp().ToString()

End Function

<WebMethod()> Public Function GenerateFingerprint(transactionkey As String, login As String, amount As Decimal, sequence As String, timestamp As String) As String

   Return AuthorizeNet.Crypto.GenerateFingerprint(transactionkey, login, amount, sequence, timestamp)

End Function End Class


If you need the rest of the code, I can send it, but these are the lines that seemed like they were the most significant. Thanks.

It not working because you can NOT use a production login ID on the test server


I try it on and getting a code (99) with a fake transactionKey, which is expected.


Get a test account

and test in to and set x_test_request to "false"

Another thing.

The way you have for GenerateFingerprint methods on the page is not secure.

The point for the fingerprint is 1)hide you transactionKey, because with both loginID and transactionKey, someone could use your info to test CC#. 2)make sure the amount is not tampered with, since both in on the form, someone change the amount from something like 126.00 to 12.60.


P.S. you have 4 decimal on the amount for the GenerateFingerPrint, it should only be just 2.

I am using a test account from Is there something that I could possibly need to change in the account that could be causing the code to think it is not a test account? To try it on with a fake transaction key, where would I get the fake transaction key? Thanks.

It is from a test account? I think you will better off  getting a new test account, it sound like it mess up on something on side and it is not code related. Maybe one on the MOD will know what to do with that one.


A fake transaction key is just that could be ABCD could be 1234. The point is that with the loginID on is returning error code 99 meaning the fingerprint is not valid, but the loginID is valid(not getting error 13).

I got a new test account and am using the new Api Login Id and Transaction Key, but still same problem. I also tried a fake transaction key, no difference.
