As of now Authorize.Net do not have ability to host the ARB Feature at their end i.e. if we wish to do a website integration with ARB Feature, we have to host the ARB at our end, I would like to suggest a feature where Authorize.Net brings in a feature making both options available to host with them or to host at the client's end. I am stuck for many days for this, I do not wish to host ARB at my end, and ARB doesn't host it at their end !!!Developers please think of this, I wish to see this feature with Authorize.Net
