A handler decides how to get a uuid or username. The default handler will just query the API and then cache the result. However you can create your own, custom handler.

There are two premade for [Bukkit](https://bukkit.org)/[Spigot](http://spigotmc.org) and [BungeeCord](https://github.com/spigotmc/bungeecord):

- [Bukkit Handler](https://gist.github.com/njb-said/cec2f56907e8eaa54021)

- [Bungee Handler](https://gist.github.com/njb-said/39e1b0fdebc18b02fc14)

Just implement these somewhere within your project and then set it as the active handler using this example (example is for the BungeeHandler.

UUIDAPI.setHandler(new BungeeHandler());

**We suggest you put it in the package:** `net.mcapi.uuid.handlers`
