**STEP 3**

{% hint style="info" %}
For Secure 3DS it may be required to pass browserData and ipAddress on the Import Order API call.
{% endhint %}

Add the hidden input browserData inside of the same form as the card input.

`<input type="hidden" name="browserData" value="" id="browserData">`

**STEP 4 (if not using CheckoutChamp page builder)**

Add this script to your page before the closing body tag.

```
Script to get browserData:
<script type="text/javascript">
    const navigator = window.navigator;
    const browserData = {
        acceptHeader: 'application/json',
        colorDepth: screen.colorDepth,
        javaEnabled: navigator.javaEnabled(),
        javaScriptEnabled: true,
        language: navigator.language,
        screenHeight: screen.height,
        screenWidth: screen.width,
        timeZoneOffset: (new Date()).getTimezoneOffset().toString(),
        userAgent: navigator.userAgent
    };
    document.getElementById('browserData').value = JSON.stringify(browserData);
</script>
```
