});

market.create_http_server();
// or
market.create_https_server({
    key: 'key',
    cert: 'cert'
});

```

Then create an event handler
```js
market.on('balance_transfer', ctx => {
    console.info(`${ctx.username} transfered to you ${ctx.amount} NLE`); 
});

```

Or use any of POST methods
```js
