Custom Payment Method,

-- url of the page with the problem -- : getmall.getthiss.com
-- Error-message(debug-mod must be tuned on) -- : ERR_TOO_MANY_REDIRECTS

My returm URL using

$return_url = HIKASHOP_LIVE.'index.php?option=com_hikashop&ctrl=checkout&task=after_end&order_id='.$order_id.$this->url_itemid;

in function onPaymentNotification(&$statuses) is working finally, after commenting out the unused hash! The order status is updating correctly to either confirmed or cancelled.

Now there's nothing wrong with the cancel url but the return url is producing the ERR_TOO_MANY_REDIRECTS error.

What can be wrong?

This problem is solved. However, I have now a blank page after a successful payment (order status updated to confirmed).

How do I write thank you for your purchase on the blank page?

Thank you.

The problem is solved. I pointed the result and cancel urls to a Joomla content page.
