The problem comes at the moment of receiving the gateway's notification of the payment. The bank requests a "response to a notification" as "a URL-coded document which only contains one text line (no HTML tags, etc.) in the format parameter=value". This parameter is the url for the user to be redirected. If I kill the application right after echoing such line, the redirection works out fine: If I use the "return true" (as other plugins do), I get an error from the payment gateway. Which makes me think that using "return" leads to other functions that write something else to that response. So my question is: is it wrong to use "exit" there? The order status changes and the user is notified that the order is confirmed. So what am I preventing Hikashop of doing? I checked the notify function in the checkout.php, but it's not clear to me what exactly is it doing.

Thank you in advance!")* Hi, If you just need to send content without HTML, the best is to use the method you use (do an exit). By doing a return, you let Joomla continue his process and it will display your content in a HTML page (using the "component.php" file from your template). So if you want to have the control on the output content, you have to use an exit. There is nothing wrong, don't worry.
