## Introduction

**MNTN Tracking Pixel** is MNTN's site-wide audience building and attribution pixel for Connected TV (CTV) advertising. This destination fires a JavaScript pixel on every page view, enabling MNTN to build audiences and attribute site visits to CTV ad exposure. There is no server-side component.

For conversion tracking (purchases, sign-ups, leads), use this destination alongside the [MNTN Conversion Pixel](#).

## Getting Started

This is a device-mode destination. The pixel fires by dynamically inserting a `<script>` tag — no manual script installation is required. You will need:

- **Advertiser ID** — your MNTN advertiser ID. This is the value of the `o` parameter in MNTN's tracking pixel snippet, found in your MNTN account.

## Connecting to the MNTN Tracking Pixel CDP Destination

:::hint{type="danger"}
Before connecting destinations in the Chord CDP, please verify with all Destination owners that all **non-Chord CDP** configured destinations are *disabled.*
**
Running external destinations alongside configured Chord CDP destinations ***can result in duplicate events downstream.&#x20;***
:::

1. Log into the Chord data platform.
2. Navigate to the CDP.
3. Click the **"Add"** button next to Destinations.
4. Select **MNTN Tracking Pixel** from the destination catalog.
5. Enter the destination name and your **Advertiser ID**.
6. Click **"Create"** to connect.

## Events

### Event Mapping

| Chord Event | Behavior             |
| ----------- | -------------------- |
| `page`      | Fires tracking pixel |
| `screen`    | Fires tracking pixel |

All other event types (track, identify, etc.) are silently skipped.

### Page / Screen Events

Fires a tracking pixel request to MNTN with referrer and page URL data.

**Pixel request:** `GET https://dx.mountain.com/spx?shaid=...&tdr=...&plh=...&cb=...`

| Parameter | Source                 | Notes                       |
| --------- | ---------------------- | --------------------------- |
| `shaid`   | Configuration          | Advertiser ID               |
| `tdr`     | `document.referrer`    | URL-encoded, max 2048 chars |
| `plh`     | `parent.location.href` | URL-encoded, max 2048 chars |
| `cb`      | Generated              | Random cache buster         |

## Initialization

The plugin does not load an external SDK. Each event fires by creating a `<script>` tag with the pixel URL as its `src` attribute, inserted before the last script tag in the document.

## CSP Requirements

If your site uses a Content Security Policy, allow the following domains:

| Directive     | Domain                    |
| ------------- | ------------------------- |
| `script-src`  | `https://dx.mountain.com` |
| `connect-src` | `https://dx.mountain.com` |
