Authorize.net using DPM API, Return URL in iframe

I am using the Authorize.net plugin with the DPM API working nicely on everything but the return back to the site. Upon completing the transaction you are posted with a message asking if you would like to go back to the store or not (I think pulling from the file authorize_thankyou.php). This is all still in the iframe and when click on the link to go back to the store it loads the thank-you page in the same iframe instead of closing the iframe and returning back to the main window.

My first thought was to use a php header redirect but I still need to close the iframe so I believe I need to use Javascript to close the window and direct the parent window to the thank-you page (where I will hopefully be able to show the order summary from com_hikashop&ctrl=checkout&task=after_end).

Am I overlooking something? Has someone encountered this problem? Any thoughts would be greatly appreciated, thank you.

Figured it out with some javascript.

<script type="text/javascript">
	function redirect(){
	window.top.location.href = "http://www.url.com/thank-you-page"
	}
	document.onload = redirect();
</script>
