### Query parameters
To pass data to GitBook through URL parameters, you’ll need to pass the data in the URL in the format `visitor.`.
For example:
```url
https://docs.acme.org/?visitor.language=fr
```
This will allow you to use these claims in the [condition editor](https://gitbook.com/docs/publishing-documentation/adapting-your-content#working-with-the-condition-editor) under the unsigned object:
```javascript
visitor.claims.unsigned.language === "fr"
```
{% hint style="warning" %}
Data passed through query parameters must be defined in your visitor schema through an [unsigned](https://gitbook.com/docs/publishing-documentation/adaptive-content/enabling-adaptive-content#setting-unsigned-claims) object. Additionally, query parameters can be easily changed by the visitor and are best suited for non-sensitive information.
