Expecting you are using the redirect procedure, the post back to your site would have to happen on the auth.net receipt page. This is unavoidable as best I know. I notice in another post that you said you changed to an iframe.
How is it possible that it would be that you use the trade data? You show your own receipt that will have the trade Id and what else? The sky is the limit for not set in stone, person, generally, and my hunch is the way isn't hard for the present circumstance.
