Elavon/Virtual Merchant - how to return to OpenCart

I have OpenCart 1.5.4.1 installed with the Elavon/Virtual Merchant extension by Qphoria. I am working with a non-hosted payment solution, so I actually transfer to https://myvirtualmerchant.com to accept the credit card information.

My question is...how do you get back to OpenCart? In the Virtual Merchant backend setup screens, there is Terminal > Payment Form > Receipt Form where you can put in a URL for Virtual Merchant to automatically return to via a "GET ReDirect". Is that how we are supposed to return to OpenCart from Virtual Merchant in order to update the customer history, record the order and clear the cart? If so, what would be the appropriate address (URL) to put in this field?

If this is not correct, does OpenCart/Elavon/VM extension pass an address to VM to return to? If so, does that take precedence over the address specified in the "Get Redirect" URL field?

THANKS!

It is all automatic as it passes the return url in the code. You can set the url on your backpanel as well, but it will be overridden by the url in the code.
