Там вы можете задать:

* "Item ID", используемый в пути.
* "Token", используемый как query-параметр.

/// tip | Подсказка

Обратите внимание, что query-параметр `token` будет обработан в зависимости.

En este ejemplo usamos headers personalizados inventados `X-Key` y `X-Token`.

Pero en casos reales, al implementar seguridad, obtendrías más beneficios usando las [Utilidades de Seguridad integradas (el próximo capítulo)](../security/index.md){.internal-link target=_blank}.
