Direct Post Method (DPM) not working

Popular shopping cart vender with connections to all the other AuthorizeNet api's already and now I'm trying to use the new DPM method.  Unfortunately, the sandbox gives you no "debug" information on errors.  It just says transaction can't process, go fish.  I have a very simple form that should be working and nothing obvious that should be a problem.

 

Here is the form page below. Note to_hash is simply debug code to show me the string that needs to be fingerprinted and it looks good to go.  I'm using authorizeNet's EncryptHMAC function.  I did rewrite it to vb.net but it seems to be functioning correctly from what I can tell.

 

Can someone please tell me why this is not working?

 P.S.  fix your gateway to spit out debug details.  It is a sandbox so there is nothing secret about having the sandbox tell you what is wrong "generically" with the post.

Re: Direct Post Method (DPM) not working

Can you set the relay response url to https://developer.authorize.net/tools/paramdump/index.php

So you can see the response. and tell us what the response are?

 

P.S. since you are using test account there is no point of setting this to true

<input type='hidden' name='x_test_request' value='TRUE' />

Just remembered, there is vb.net sample code for SIM here, which have the code to generate the x_fp_hash.

Thanks for your reply and your help.

 

Yeh, I don't think the test request is going to make a difference.  I have set that to true and false.

I changed the relay response to what you suggested.....and I get the same error...which is:

 

An error occurred while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card. 

      This transaction cannot be accepted. 
      
 

 The email you receive is this:

 

**Please DO NOT REPLY to this message. E-mail developer@authorize.net if you have any questions.

Authorize.Net Developer Center Merchant,

Your script timed out while we were trying to post transaction results to it.
   Transaction ID: 0
Transaction Result: This transaction cannot be accepted.

The following message was displayed to the customer:

------------------------------An error occurred while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card.

This transaction cannot be accepted.


------------------------------

 Neither are useful.

When I go to that url directly it says:

Page Not Found   Sorry, the page you requested was not found or may have been moved. In order to find the correct page, we suggest the following:

Ok, I did a search for the correct URL on that param dump and found it.

This is what I get:

I think that is saying the Hash is not correct.  However, I am using AuthorizeNET's hash algorithm to generate it.  The only thing I did was convert the code to VB.NET from C#.

use the Response Code 99 Tool to test your x_fp_hash or post your vb.net rewrite.

Re: Direct Post Method (DPM) not working

Ok, I have confirmed the hash is working now from that last sample.

 

I still get a failure though when I set the relay response to my url:

 

An error occurred while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card.

      This transaction has been approved.

It is advisable for you to contact the merchant to verify that you will receive the product or service.

 

But it looks fine when I look at the relay post url

 

REQUEST_METHOD:POST
HTTP_REFERER:none

This is a test mode transaction.

Re: Direct Post Method (DPM) not working

first go thru the check list in Relay Response Basics and Troubleshooting

 

then for asp.net set EnableViewStateMac="false" on both page the post to authorize.net and the relay response page.

Re: Direct Post Method (DPM) not working

Ok, this is DPM not SIM, but I assume it is the same.  I actually put the relay url to a basic website...just to show completion....  I think I even tried www.microsoft.com.   I assume the relay url can just be a plain old url that does nothing....

Re: Direct Post Method (DPM) not working

need to be a page that can accept a form post to it. so just a .html page will not work. The other thing that I remember is that the relay page can't have any field with the same name as any of the response field name. e.g. x_response_code.

 

Can you post the relay response page.
