For anyone else using the Live Form Extension :Authorize.NET to capture payments, you may run across a case where the Action in Form Submission fails but there is no Response. There will be no information as to why the Action failed at all.

You will not be able to troubleshoot an Action failure that has already occurred but you can enable verbose logging to try to capture any future errors. The AuthorizeNET.dll that ships with the Live Form Extension has Trace Log messages in it that can tell you what is occurring.

If you are running DNN on a server, you could use Microsoft Windows Sysinternals DebugView to capture the Trace.

If you are running DNN in Azure, you can go to Monitoring in your App Service to turn on Application Logging and set the Level to Verbose.

While I have been able to track down one possible reason for an Authorize.Net Action failure, there is another one occurring that I have not been able to determine the source. (Note:Authorize.NET has limits on the length of the fields it is sent.) The above trace logging should help with that.

Hopefully someone finds this information useful for tracking down issues they may be having.
