How to Disable the WordPress REST API Requests The Easy Way

Last Updated on December 11, 2023 by Mike Kipruto

Today I want to share a quick and easy tutorial on how to disable the WordPress Rest API for nonlogged and redirect them to home in WordPress using custom code.

To achieve this, we will use the following code that hooks into the WordPress “rest_authentication_errors” filter hook.

 */
add_filter( 'rest_authentication_errors', function ( $result ) {
    // If the user is not logged in, redirect to the home page.
    if ( ! is_user_logged_in() ) {
        wp_redirect( home_url() );
        exit;
    }
    return $result;
});
