Vamos ver tudo isso com um exemplo.

Imagine que você desenvolve um aplicativo que permite criar faturas.

Essas faturas terão um `id`, `title` (opcional), `customer` e `total`.

O usuário da sua API (um desenvolvedor externo) criará uma fatura na sua API com um request POST.

Então sua API irá (vamos imaginar):

* Enviar a fatura para algum cliente do desenvolvedor externo.
