El usuario de tu API (un desarrollador externo) creará una factura en tu API con un request POST.

Luego tu API (imaginemos):

* Enviará la factura a algún cliente del desarrollador externo.
* Recogerá el dinero.
* Enviará una notificación de vuelta al usuario de la API (el desarrollador externo).
    * Esto se hará enviando un request POST (desde *tu API*) a alguna *API externa* proporcionada por ese desarrollador externo (este es el "callback").
