@WarmBeer why do you need to expose the reload whitelist (GET /api/whitelist/reload) and keys (GET /api/keys/reload) "commands" in the API?

@josecelano ,

These commands are for reloading the states from the database. This is useful when an administrator wants to update the tracker whitelist using the database for example.
