### JavaScript Response Transformer

If you want to transform unstructured responses – you can use a JavaScript response transformer. `data` is a variable that stores a response to your request. To do so, follow the steps:

1. Click on the `Transform` button
2. Choose **JavaScript Transformation**
3. Write your custom script using `data` variable
4. Click on the `Run` button to send a request
5. Click on the `Save` button to save it

For example, you can use JS functions to parse the data:

```
function getProperties(data) {
    result = {};
    for (var key in data) {
        result[key] =  data[key]['value'];
    }
    return result;
}

function contactMapper(contactData) {
    result = getProperties(contactData['properties']);
    result['dealId'] = contactData['dealId'];
    return result;
}
return  data['deals'].map((x)=>contactMapper(x));
```
