The Axon pixel collects event data from your website to power AppLovin's ad optimization engine. # Getting Started This is a device-mode destination requiring an Axon Event Key for connection. You can obtain the Event Key from your AppLovin dashboard. # Initialization When the Axon destination is enabled, p.js injects the Axon pixel scripts into the page on first event: - `https://s.axon.ai/pixel.js` - `https://c.albss.com/p/l/loader.iife.js` Before the scripts load, a `window.axon` stub is created that queues all calls. Once the real SDK loads it replays the queue automatically, so no events are lost during initialization. `axon("init")` is called immediately after the stub is created to begin the SDK initialization handshake. Preconnect and DNS-prefetch hints for `https://s.axon.ai` and `https://c.albss.com` are also injected to reduce script load latency. # Connecting to the Axon CDP Destination :::BlockQuote **Warning:** 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.** ::: 1. Log into the Chord data platform. 2. Navigate to the CDP. 3. Click the **"Add"** button next to Destinations. 4. Select **AppLovin Axon** from the destination catalog. 5. Enter the destination name and **Axon Event Key**. 6. Click **"Create"** to connect. # Events ## Event Mapping Chord event names are mapped to Axon standard event names. Unmapped event names are passed through as-is. ### Required Events (Purchase Sites) | Chord Event | Axon Event | | ---------------- | --------------- | | Product Viewed | view\_item | | Product Added | add\_to\_cart | | Checkout Started | begin\_checkout | | Order Completed | purchase | ### Recommended Events | Chord Event | Axon Event | | -------------------------- | ------------------ | | Payment Info Entered | add\_payment\_info | | Cart Viewed | view\_cart | | Product Removed | remove\_from\_cart | | Products Searched | search | | Signed Up | sign\_up | | Logged In / User Logged In | login | | Subscribe / Subscribed | subscribe | | Lead Generated | generate\_lead | # Event Details ## Page Fires an Axon page view tracking call. **Axon SDK call:** `axon("track", "page_view")` No additional attributes are sent with page events. *** ## Identify Sends user identity to Axon. **Axon SDK call:** `axon("identify", userId, traits?)` | Axon Attribute | Chord Source (Priority Order) | Notes | | -------------- | ----------------------------- | -------------------------------------------- | | `userId` | `userId` > `anonymousId` | Required; event is skipped if neither is set | | `traits` | `traits` | Optional; only sent if non-empty | *** ## Track Sends a tracked event to Axon.
