ASP.Net Relay Response?

Ok, so I've done searches on the forums and it seems that either a) most people haven't gotten a thorough response or b) there really is no response to this question.


When receiving a relay response, my asp classic code works fine... And when I code up a page to accept this same information in, it does not. My question is this: Is it not possible to use .net to accept the relay response? The only code provided for relay response is asp classic (which is what I ran the test with). It works great; however, I don't code in asp classic. :) It'd be nice to actually be able to use this data returned in a method that is not implimented in classic. Is my only option to accept the data with the classic code and send that data to another page?


Any help is greatly appreciated.


I am having the same issue and could not find anything in the forums.


The way I got around it but not a pretty solution was what you are talking about. I basically used their example and created a classic asp page to receive the relay_response back. Then I built (response.write) a form to pass the data to an form to process the information (save to db and create email reply).

It works fine, except having an issue with FireFox (another post).


It would be nice to be able to skip that step.

Hi, I'm having the same problem with ASP.NET, but I can't find any example of how to do this, mixing classic ASP and ASP.NET. I never used classic ASP before and I don't know where to start. I looked at the Authorize examples in the Relay Response Section (the classic ASP example), but I don’t know how to pass that data to a ASP.NET form.

Can you provide me some direction for me to look? Any help will be appreciated.

First let me say that I am not a ASP.NET programmer so I cannot explain things in a technical way. However, all relay response does is send a POST request to a page and then take the results of that rerquest and print them to the screen for the user to see. So, all your ASP.NET page needs to do is handle the POST request, which is the same as a Silent Post request and output a recipt/confirmation to your users. It's really no different then handling a standard form submission.

Hi John,


Thank you for answer. I’m having a hard time with this issue and any help is appreciated.


I have a very simple ASP.NET form as a relay response page. The only thing it does (for testing purposes) is to take the values received and put them in string variables, that’s all, no database access, no email sending, etc.


That works fine in test mode (testMode=”TRUE”) but as soon as I change to real mode (testMode=”FALSE”) I get this message when I click the Submit button in the payment form:


“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.”


Additionally I receive an email with this message:


“Your script timed out while we were trying to post transaction results to
   Transaction ID: xxxxxxxxx
Transaction Result: This transaction has been approved.”


I get this error 2 or 3 seconds after clicking the submit button in the payment form, so I think the problem is not a real time out, taking in account the simplicity of my page and the fact that it does work in test mode.


I talked to Authorize’s tech support and the person who spoke with me told me that I should use classic ASP in the relay response page, not ASP.NET. Maybe the problem has other causes but for now I don’t know what to do.


I’m aware of the fact you are not an ASP programmer, but I put here the code anyway, because is so simple. And maybe you can see something I missed. Thanks again.

This is usually the result of an error in the page. The first thing you need to do for testing is submit a fake POST request directly to you relay response page so you can see the results in web browser. If there is an error you should see it there.

I already did that, using your script at

It works without errors. It also works in test mode. Just did not work in real mode. Did you see all I do is to store the values I receive in string variables? How can that throw a time out error?

I'm really sorry. It was my mistake: I was trying to cast the value of x_trans_id to Integer and that produced the error, it never happened in test mode because in that mode x_trans_id is always 0. I got confused by the error message from Authorize, the real problem was not related to a time out error.


So if you are having a time out message before the 10 seconds Authorize will wait to really throw a time out error, chances are that the problem is really an error in your code.



I'm getting the same error.  No errors when I send a test post to the page.  I've even removed every line of code and I still get the errors.
