[Globalevel]

A little new..just got started with Authorize.net...I can't seem to post a transaction...not getting any error msgs...be nice to have that..code portion below.

You mean post_response is blank?

[Globalevel]

yes...that will give me error return/debugging?  uncomment this;?

Dim response_array As Array = Split(post_response, post_values("x_delim_char"), -1)

        ' the results are output to the screen in the form of an html numbered list.
        'resultSpan.InnerHtml += "<OL>" & vbCrLf
        'For Each value In response_array
        '    resultSpan.InnerHtml += "<LI>" & value & "&nbsp;</LI>" & vbCrLf
        'Next
        'resultSpan.InnerHtml += "</OL>" & vbCrLf
        ' individual elements of the array could be accessed to read certain response
        ' fields.  For example, response_array(0) would return the Response Code,
        ' response_array(2) would return the Response Reason Code.
        ' for a list of response fields, please review the AIM Implementation Guide

....also...I dont have the post_url...should it be this..customer service just sent it to me:

post_url = https://secure.authorize.net/gateway/transactdll

[Globalevel]

oopps..I meant this:

 Dim response_array As Array = Split(post_response, post_values("x_delim_char"), -1)
        '   the results are output to the screen in the form of an html numbered list.
        resultSpan.InnerHtml += "<OL>" & vbCrLf
        For Each value In response_array
            resultSpan.InnerHtml += "<LI>" & value & "&nbsp;</LI>" & vbCrLf
        Next
        resultSpan.InnerHtml += "</OL>" & vbCrLf & " Response Code: " & response_array(0) & _
 ", Response Reason Code: " & response_array(2) & "."
        '   individual elements of the array could be accessed to read certain response
        '   fields.  For example, response_array(0) would return the Response Code,
        '   response_array(2) would return the Response Reason Code.
        '   for a list of response fields, please review the AIM Implementation Guide

[Globalevel]

fyi..I am using the AIM...

[RaynorC1emen7]

That will put the result on the screen. The production url is(there is a period before the dll)

https://secure.authorize.net/gateway/transact.dll

And the test site url is

https://test.authorize.net/gateway/transact.dll

Production LoginID, transactionKey will not work on the test site or vice versa

[Globalevel]

okay so i made the necessary changes....got some errors:

Response Code: 2

Response Reason Code: 205

Response Reason Code: 205

Response Reason Text: This transaction has been declined.

Other Suggestions: This error code applies only to merchants on FDC Omaha. The value submitted in the merchant number field is invalid.

So I very my API login(x_login) and transaction(x_tran_key) ....it created another tran key..okay and confirmed that info...thats good to go...so not sure what else to do here...I also that that I should have the state collexted in the post_values.add...

[RaynorC1emen7]

Read the following

http://community.developer.authorize.net/t5/Integration-and-Testing/Error-response-2-205/m-p/694

[Globalevel]

okay..I see this in your link:

Tell whoever provides your merchant account that you need the document that contains all of the details about your account so that you can pass it on to Authorize.Net to configure your payment gateway account.  This document will contain information like your "Acquirer BIN", "Store Number", "Merchant Number", and a bunch of other fields.

If you already have an Authorize.Net account, then you should have already received one of these and given it to Authorize.Net when you first established your account.  If you can find that, and it just needs to be refreshed for some reason, then having the older one would help describe what you are looking for.

.......

a few things:

1. I thought authorize.net provided the details of the account...I thought authorize.net had my merchant account...

>>>If you already have an Authorize.Net account, then you should have already received one of these and given it to Authorize.net...dont they have it already???

2. I do have an authorize.net account....I guess I recieved one of these??

....do I need to contact someone like the bank??

[RaynorC1emen7]

Call authorize.net up and tell them the error message, and see what they tell you.
