Is there any instant payment notification system in Authorize.Net which will run a 'URL' with posting all the values of user input, like in Paypal. If anyone has userful link on it or any alternative that can help me on instant notification onAuthorize.Net, please share.
They do. It's called Silent Post.
They also now offer Webhooks which is a bit more complicated than Silent Post but offers much more flexibility and power.
