Authorize.net Script

I need an [login to view URL] script that will let my customers make payment on my website and get approved or denied right there. Right now I just collect the credit card information and then log-into [login to view URL] and fill in the same info into the gateway. I just need the customer to enter the same info on my site and let [login to view URL] process it in the background. Please I am not interested in some long resume about all kinds of work you have done that is unrelated to authorize.net.I just need to know If you have done specifically this kind of work before and if you can show me examples.
