Any once please help me out for overwrite the REST api in magento 2.3 please describe with example.


You need to create a webapi.xml file under etc folder within your custom module


<?xml version="1.0"?>

<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  <route url="/V1/customers" method="POST">
    <service class="VendorName\ModuleName\Api\AccountManagementInterface" method="createAccount"/>
        <resource ref="anonymous"/>

You need to define interfaces same as AccountManagementInterface of customer module. I hope it will work. Let me know if you need further help :)

  • what do you want to achieve by overriding endpoint? – Ramkishan Suthar Mar 29 '19 at 6:31
  • I have created some custom attribute so i would like to get in response that's why i need to overwrite the above API. Can you please help me to solve this "EmailNotificationInterface does not exist" error? – Vishal Bansal May 13 '19 at 5:38

If you want just add some custom data to response, there is no reason to do some overrides. You can archive this with use of extension attributes there I provided an example (about quote item, but for Customer idea should be the same). If you don't know about extension attributes there a good starting point.
