# Query string

The querystring option allows to pass query parameters onto the LiSA player, e.g. for tracking purposes.

Please make sure to URL-encode the query string (partial).

```
window.LiSA.library.configs.push({
  querystring: encodeURIComponent('utm_source=foo&utm_campaign=bar'),
});
```

The query string parameters provided with the querystring option will also be included in all URLs generated by the LiSA player, either for setting calendar events or social sharing.
