function get_page_by_post_title( $page_title, $output = OBJECT, $post_type = \'page\' ) {
    global $wpdb;

    $sql = $wpdb->prepare(
        "
        SELECT ID
        FROM $wpdb->posts
        WHERE post_title = %s
        AND post_type = %s 
        ORDER BY ID DESC
    ",
        $page_title,
        $post_type
    );

    $page = $wpdb->get_var( $sql );

    if ( $page ) {
        return get_post( $page, $output );
    }
}

function get_inquiry_id($data){ 
    $return = []; 
    $title=$data[\'title\']; 
    $return = get_page_by_post_title($title, OBJECT, \'inquiry\'); 
    $return = $return->ID; 
    return new WP_REST_Response($return, 200); 
}
