Redirect user back to site from Authorize.net

I just purchased the Authorize.net SIM plugin. I cannot figure out how to redirect the user back to my site after payment. The user just stays on Authorize.net's thank you page. How do I redirect the user back to my site?

Hi

I am sorry. With the current Authorize.net SIM API, users could not redirected back to your site automatically after making payment. If you can help me by contact Authorize.net and ask them whether they provide us a way to do that or not, that would be great.

From their documentation, I don't see anyway.

Regards,
