# Unbounce

Install the Coframe SDK on an Unbounce landing page

This guide is for landing pages built and hosted on Unbounce. Unbounce provides
a JavaScript panel in the page editor that lets you inject scripts into the
`<head>` of a page, which is where the Coframe installation script needs to go.


If your site is not on Unbounce, see the [JavaScript guide](../docs/javascript.html)
for general HTML-based installation.



[Video: Video: adding the script with Head placement, publishing, and verifying in DevTools (65s, narrated)](assets/videos/fig15-install-unbounce.mp4)
Watch: 65s — adding the script with Head placement, publishing, and verifying in DevTools

## Unbounce steps

- Open your page in the Unbounce page editor.


- At the bottom of the editor, click the JavaScript panel.


- Click +Add New JavaScript.


- Name the script `Coframe`.


- Set Placement to Head.


- Paste the installation script (see below) into the code area.


- Click Save & publish.



The script must be added with Head placement — do not load it through an
async tag manager such as Google Tag Manager. Because anti-flicker is enabled,
the script needs to run synchronously before the browser renders the page body.
Loading it asynchronously through a tag manager defeats this and will cause a
visible flash of unstyled content.

## Installation script

Copy the script below and paste it into the Unbounce JavaScript panel. Replace
`YOUR_PROJECT_ID` with the project ID from your Coframe dashboard.


HTML



```html
<script id='coframe-installation-script'>
  (function () {
    // Early exit for performance testing
    if (/cf_disable/.test(location.search)) return console.warn('[Coframe] Disabled via URL parameter');
  
    // Coframe config
    const config = {
      projectId: 'YOUR_PROJECT_ID',
      startTime: Date.now(),
      timeoutMs: 1000,
      currentUrl: window.location.href,
    };
  
    // Prevent duplicate installation
    const script_id = 'coframe-sdk-js';
    if (document.getElementById(script_id)) return console.warn('[Coframe] SDK already installed');
  
    // Coframe queue setup
    (window.CFQ = window.CFQ || []).push({ config });
  
    // Coframe antiflicker CSS
    const style = document.createElement('style');
    style.id = 'coframe-antiflicker';
    style.textContent =
      ':root { --cf-show: 0;}' +
      'body { opacity: var(--cf-show) !important; transition: opacity 0.2s ease; }'
    function hide() { document.head.appendChild(style); }
    function show() {
      document.documentElement.style.setProperty('--cf-show', '1');
      style.parentNode && style.parentNode.removeChild(style);
    }
    hide(); setTimeout(show, config.timeoutMs);
  
    // Coframe SDK JS
    var edgeUrl = new URL('https://edge.cofra.me/cf.js');
    edgeUrl.searchParams.set('config', encodeURIComponent(JSON.stringify(config)));
  
    const script = document.createElement('script');
    script.id = script_id;
    script.async = true;
    script.src = edgeUrl.toString();
    script.onerror = () => { show(); console.error('[Coframe] SDK failed to load'); };
    document.head.appendChild(script);
  })();
</script>
```

## Verify it is working

After saving and publishing your Unbounce page:



- Open the live page in a browser, then open the browser console and confirm
there are no `[Coframe]` error messages.


- In the Network tab, look for a request to `edge.cofra.me/cf.js`. A
successful `200` response means the SDK loaded correctly.


- Check that a `coframe-sdk-js` script element appears in the DOM (you can
inspect the `<head>` in the Elements panel).





For a full walkthrough of how to validate the integration and confirm that
Coframe is operating as expected, see
[Testing and Validation](../docs/testing-and-validation.html).

## Optional configuration

The default script is designed to work without additional configuration. Once
the SDK is installed, you can tune behavior using the following guides:



- [SDK options](../docs/sdk-options.html) — timeout, disable conditions,
and other core settings


- [Identity settings](../docs/identity-settings.html) — associate SDK
activity with a known user identity


- [Tracking settings](../docs/tracking-settings.html) — control which
events and page interactions Coframe records


- [Anti-flicker](../docs/anti-flicker.html) — understand how the anti-flicker
mechanism works and how to adjust it for your performance requirements
