How it flows
How a Skio event reaches AppLovin. Captured by the Upstack Pixel, resolved to a person, then reported through the Axon Pixel.
01 Capture
Captured from Skio
Capture Skio subscription events server-side, with the first charge distinguished from every renewal that follows it.

02 Understand
Resolved to one person before it leaves
Every Skio event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.

03 Activate
Delivered to AppLovin
Upstack loads the AppLovin Axon Pixel on your storefront and reports each event with identity data and the aleid click ID attached, so conversions are attributed to your AppLovin campaigns.

Which events reach AppLovin
Each Upstack event is mapped to the AppLovin event below before it is sent.
| Upstack event | Sent to AppLovin as | Key data on the event |
| Page view | page_view | url, referrer |
| Product view | view_item | items, value, currency |
| Add to cart | add_to_cart | items, value, currency |
| Checkout | begin_checkout | items, value, currency |
| Purchase | purchase | transaction_id, value, tax, shipping, items |
Events carry email, phone and client_id when available, plus the aleid click ID for deterministic matching. The Send User Data setting includes hashed user data for better match quality.
The catch
AppLovin receives events from the browser only.
Upstack loads the Axon Pixel for you, so remove any other Axon tag in your theme, Google Tag Manager or another app: two tags with the same Pixel ID can double count events.

What changes
What changes when Skio feeds AppLovin. Two gains on the AppLovin side, two on the Skio side.
AppLovin
The Axon Pixel, loaded for you
Upstack loads the Axon Pixel once the destination is saved, so there is no separate Axon tag or second set of event mappings to maintain.
AppLovin
Identity-resolved events
Events sent to AppLovin carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.
Skio
Every event, server-side
Storefront and checkout events are captured from Skio on the server, independent of the browser.

FAQ
Questions about Skio and AppLovin.
Do I need to keep my own Axon tag on the storefront?

Which events does AppLovin receive?
PageView as page_view, ViewContent as view_item, AddToCart as add_to_cart, InitiateCheckout as begin_checkout and Purchase as purchase, reported from the browser through the Axon Pixel. Remove from cart, view cart, add payment info, search, lead, sign-up and subscribe are mapped too.
Which customer parameters are sent to AppLovin?
