**STEP 3**

For Secure 3DS it may be required to pass browserData and ipAddress on the Import Order API call.

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

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

**STEP 4**

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>
```

**STEP 5**

For Secure 3DS the checkout and upsell pages must support 3DS redirects
