Authorize.net: Your transaction could not be completed.

Hi, sorry to bother you again, thanks to your help I'm really close to finish this project. I got the UPS real time quote working perfectly now (thanks to you) but something is going on in the checkout process itself. I have read the forum and noticed that you recommend to add that bunch of code for testing and getting a full response of the problem, what I did, I inserted the code in my checkout_failure.php page and... nothing happens! That's why I'm contacting you, I suspect something bigger is going on behind the scenes, and I cannot handle that. Any idea guys? Thanks in advance.

ps: I have tried the error response code in both the body as well as on the first lines of the page, and same result, nothing gets rendered on the screen.

the code block you are using will only work for power store.

Use this code block instead:

<?php

    if(!session_id()) session_start();

     echo "<p>Auth Net: <br />"; 

     echo "Full Request: ".(isset($_SESSION['WAAuthNet_postedValues'])?htmlentities($_SESSION['WAAuthNet_postedValues']):"n/a")."<br />"; 

     echo "Full Response: ".(isset($_SESSION['WAAuthNet'])?htmlentities($_SESSION['WAAuthNet']):"n/a")."<br /></p>"; 

?>
