SIM questions

[dadamssg]

Can you set a different type of transaction using SIM? i.e. "auth_only"

Can you get a response somehow using SIM? i.e. amount of transaction, customer name, transaction id

Strange..

In my own code I dont use the same page the form is on as the x_relay_url.

You might try changing the x_relay_url to a different page (???)

Maybe, since AuthNet is basically firing up "http://mysite.com/auth/index.php" to get to the form, it is confused and says "Oh, I'm already here anyway".

Not sure, but that's the first thing I'd change.

Tried changing x_relay_url to a different page and it threw an error. Then i removed the hidden x_relay_url input from the form to see what happenned and it still worked like it was(displayed my page but with the auth url). 

I guess it doesn't really matter as long as i use absolute url links in my response/relay page and i can still use my server to handle the POSTs...
