**STEP 3**

Fill the fields obtained in Step 1.

Select “No” on **secure3DS** if it is for Non-3DS. Use **force3DS** to require 3DS from Adyen.

Use **enableCardOnFile** to set the processing model to Card On File and Subscription.  The default is Unscheduled Card on File.

Set **useTestServer** to use Adyen's test environment.  Be sure to uncheck this when ready for live traffic.

{% hint style="info" %}
The following steps are for pages hosted outside of Checkout Champ
{% endhint %}

**STEP 4**

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

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

&#x20;

**STEP 5**

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

```javascript
<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 6**

For 3DS and alternate payments, your checkout page must support the standard 3DS workflow

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

**STEP 7**

Extra Risk Management

Checkout Champ supports a device fingerprint passed from the page.  Follow these instructions from Adyen.  Pass the generated fingerprint to [Import Order API](https://apidocs.checkoutchamp.com/#275a54c6-b4b0-414c-819b-7387e9a81f58) as **fraudSessionId**.

If using Checkout Champ hosted pages, set the id of the hidden field to **fraudSessionId** and it will be automatically passed at checkout.
