## Types en Validatie

But for now, let's check these important **conceptual ideas**. These concepts also apply to any other type of web API. 💡

## Security - HTTPS { #security-https }

In the [previous chapter about HTTPS](https.md){.internal-link target=_blank} we learned about how HTTPS provides encryption for your API.

Events
======

Events allow you to capture metrics on your application’s HTTP calls. Use events to monitor:

 * The size and frequency of the HTTP calls your application makes. If you’re making too many calls, or your calls are too large, you should know about it!
 * The performance of these calls on the underlying network. If the network’s performance isn’t sufficient, you need to either improve the network or use less of it.

### EventListener

        SmbException ex = new SmbException(0, false);
        assertEquals("NT_STATUS_SUCCESS", ex.getMessage());
        assertEquals(0, ex.getNtStatus());
        assertNull(ex.getRootCause(), "root cause should be null for this ctor");
        assertEquals("jcifs.smb1.smb1.SmbException: NT_STATUS_SUCCESS", ex.toString());
    }
