Is it safe to not implement HttpPostActionInterface ?


class NewAction extends SubscriberController implements HttpPostActionInterface


class NewAction extends SubscriberController

My goal on removing the implement HttpPostActionInterface was to prevent the page on displaying the 404 page if no post was sent. Our requirement was only to display a blank page when user manually load the link.

Or if you have other option on displaying blank page instead displaying 404 not found content.

Other Classes connected/extended that might help:


abstract class Subscriber extends \Magento\Framework\App\Action\Action


abstract class Action extends AbstractAction


abstract class AbstractAction implements \Magento\Framework\App\ActionInterface

Your Controller Must Implement POST or GET Action Interface Class Other wise it will give you 404 No Found to your request

if your controller SubscriberController is implement any of ActionInterface its okay you don't need to implement that again


The Class \Magento\Framework\App\Action\Action can be used but it is depreciated after Magneto 2.4 so it's a good practice to implement PostActionInterface

  • Hello thank you for the reply, the SubscriberController doesn't implement it, but it extends \Magento\Framework\App\Action\Action . Is it okay ? Commented Oct 7, 2021 at 9:05
