Working with github enterprise

Is there a way to use this lib with Git-Hub Enterprise?

I tried this as below but it doesn't seem to work. Please let me know what I'm missing.

```
const token = process.env.GIT_API_TOKEN,
apiBase = 'https://git.company.com/api/v3',
GitHub = require('github-api'),
gh = new GitHub({ token, apiBase });

let me = gh.getUser();
me.listNotifications(function(err, notifications) {
console.log(notifications);
});
```
