Disable JSON REST API

Hi @arnoldwillems

I hope you are doing well.

I am afraid we don’t have this option, I found this was requested in the past by our developers and I added this ticket as an extra request letting our developers know you are also looking for it.

However, to disable the Rest API you can use this filter:

<?php
 add_filter( 'rest_authentication_errors', 'wp_snippet_disable_rest_api' );
   function wp_snippet_disable_rest_api( $access ) {
      return new WP_Error( 'rest_disabled', __('The WordPress REST API has been disabled.'), array( 'status' => rest_authorization_required_code()));
   }
?>

Since Rest API is used by Gutenberg I suggest adding some extra validation to prevent issues with WP editor or other plugins.

You can apply it as a mu-plugin https://wpmudev.com/blog/wordpress-mu-plugins/
