**STEP 3**

Apply the gateway to your offers and upsells within the campaign.

**Secure 3DS:**

If using native (challenge) 3DS, be sure to follow proper instructions on the checkout page

[Basic 3DS Instructions](/konnektive-crm/gateway-setup/basic-3ds-instructions.md)

3DS requires that certain browser information be included on the Import Order API call:

* Add a hidden input for browserData

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

* Add below script before closing “body” tag.

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