Are you looking for a way to disable JSON Rest API in WordPress? While there’s probably a plugin for this, we have created a quick code snippet that you can use to disable JSON Rest API in WordPress.
The REST API feature was introduced in WordPress 4.4. These features make it possible to access your content through a JSON API, which is awesome for external services and clients.
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
add_filter('json_enabled', '__return_false'); add_filter('json_jsonp_enabled', '__return_false');
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.
