I am trying to add a new action to the existing module Magento_Customer.

My module has the following namespace Custom_AccountReferral

I need to add a new action customer/account/referral/

I have create a custom module and it works.

  1. Create a new controller inside my module directory AccountReferral/Controller/Account the file with name Referral.php
  2. Create the routes.xml file inside etc/frontend/ directory

With the following content

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    <router id="standard">
        <route id="customer" frontName="customer">
            <module name="Custom_AccountReferral" before="Magento_Customer"/>
  1. Also tried to add the following line to the di.xml file

    preference for="Magento\Customer\Controller\Account\Referral" type="Custom\AccountReferral\Controller\Account\Referral"/>

But unfortunately it still gives me the 404 page

Whoops, our bad...

Please suggest how to add a new action to existing module routes.



The content of the Referral file

namespace Custom\AccountReferral\Controller\Account;
class Referral extends \Magento\Customer\Controller\AbstractAccount {

    protected $customerRepository;

    protected $dataObjectHelper;
    protected $session;

    protected $resultPageFactory;
    public function __construct(
        Context $context,
        Session $customerSession,
        PageFactory $resultPageFactory,
        CustomerRepositoryInterface $customerRepository,
        DataObjectHelper $dataObjectHelper
    ) {
        $this->session            = $customerSession;
        $this->resultPageFactory  = $resultPageFactory;
        $this->customerRepository = $customerRepository;
        $this->dataObjectHelper   = $dataObjectHelper;
        parent::__construct( $context );

    public function execute() {
        $resultPage = $this->resultPageFactory->create();

        $block = $resultPage->getLayout()->getBlock( 'customer_account_dashboard_referral_edit' );
        if ( $block ) {
            $block->setRefererUrl( $this->_redirect->getRefererUrl() );

        $data               = $this->session->getCustomerFormData( true );
        $customerId         = $this->session->getCustomerId();
        $customerDataObject = $this->customerRepository->getById( $customerId );
        if ( ! empty( $data ) ) {
        $resultPage->getConfig()->getTitle()->set( __( 'Referral Settings' ) );

        return $resultPage;

This is just an example, I haven't added any logic yet, because it is not accessible.

You need to inherit this way; Replace this code .

namespace Custom\AccountReferral\Controller\Account;

use Magento\Customer\Controller\Account\Referral;

class extends Referral

Starting on as you say that your module works, your controller should be in this path :

app/code/{Vendor}/{Module}/Controller/Account/Custom // Account/Custom is for exemple

The content should be something like this:


namespace Vendor\Module\Controller\Account;

class Custom extends \Magento\Framework\App\Action\Action

    protected $_registry;
    protected $_pageConfig;

    public function __construct(
        \Magento\Framework\Registry $registry,
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Page\Config $pageConfig
    ) {
        $this->_registry = $registry;
        $this->_pageConfig = $pageConfig;

    public function execute() {
        echo "My controller works fine !";

Now you can call your controller like this : baseurl/frontname/foldercontroller/filecontroller


To add a new action in core module Magento_Customer you need to extend first that module then you add what you need, I see that you are using customer as frontName in you xml and this frontName 'custom' is already reserved ! you can use it again if you extend his module.

See this to how extend an exsting core module : Magento 2 how to extend core module

Good luck.
