General

The correct way to add scripts in WordPress is using wp_enqueue_script()

https://developer.wordpress.org/reference/functions/wp_enqueue_script/

Place the following code in functions.php:

function custom_wp_enqueue_scripts() {
    wp_enqueue_script('script-name', get_template_directory_uri() . '/path/to/script/name.js', array(), '1.0.0', false);
}
add_action('wp_enqueue_scripts', 'custom_wp_enqueue_scripts');

Note the 5th argument is false . This adds the script to the head rather than the end of the body.

Your specific case:

function custom_wp_enqueue_scripts() {
    wp_enqueue_script('web-manager', 'domain.tld/js/web-manager.min.js', array(), '1.0.0', false);
}
add_action('wp_enqueue_scripts', 'custom_wp_enqueue_scripts');

Because your script requires the async and data-key="abc123efg" attributes you must also add this code to functions.php:

function custom_script_loader_tag($tag, $handle, $src) {
  if ('web-manager' === $handle) {
    $tag = '<script type="text/javascript" async src="' . $src . '" data-key="abc123efg"></script>';
  }
  return $tag;
}
add_filter('script_loader_tag', 'custom_script_loader_tag', 10, 3);
