...o Python tem uma pequena sintaxe especial para isso.

Passe `*`, como o primeiro parâmetro da função.

O Python não fará nada com esse `*`, mas saberá que todos os parâmetros seguintes devem ser chamados como argumentos nomeados (pares chave-valor), também conhecidos como <abbr title="Do inglês: K-ey W-ord Arg-uments"><code>kwargs</code></abbr>. Mesmo que eles não tenham um valor padrão.

The only new thing is the `callbacks=invoices_callback_router.routes` as an argument to the *path operation decorator*. We'll see what that is next.

The actual callback code will depend heavily on your own API app.

Aquí estamos usando `Query()` porque este es un **parámetro de query**. Más adelante veremos otros como `Path()`, `Body()`, `Header()`, y `Cookie()`, que también aceptan los mismos argumentos que `Query()`.
