Each event is resolved to a person against a 750M+ device graph, then reported to AppLovin through the Axon Pixel with the aleid click ID attached. AppLovin receives events from the browser only.
How it flows
01 Capture
One Upstack app setup that captures Shopify storefront and checkout events with the Upstack Pixel, records every order directly from Shopify, and forwards both to every tool you spend on.
See the Shopify integration

Every Shopify event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.
How resolution works
customer_typeNew or returning, resolved before send.Ad platforms accept almost anything and tell you very little. These controls exist so you can see what was sent and what was accepted, rather than inferring it from a reporting gap.
03 Activate
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.

Shopify to AppLovin, in detail
Upstack tracks AppLovin through the Axon Pixel on your storefront. The Upstack Pixel captures each event and enriches it with identity and click-ID data, then Upstack loads the Axon Pixel and reports the event to AppLovin with the aleid click ID attached. Because Upstack owns the capture, AppLovin events carry the same identity data as the rest of your tracking, with no separate Axon tag or second set of event mappings.
| Shopify data | Sent to AppLovin as |
|---|---|
| AppLovin ad click Captured from the landing URL for deterministic matching. | aleid |
| Checkout email and phone Hashed user data, when Send User Data is on. | email, phone |
| The visitor One of the identifiers AppLovin matches on. | client_id |
| Products, total and currency On view_item, add_to_cart and begin_checkout. | items, value, currency |
| Order On purchase. | transaction_id, value, tax, shipping, items |
AppLovin currently receives events from the browser only: with LinkedIn, it’s one of two destinations whose Tracking Method offers just Browser. The browser path can be blocked by ad blockers and browser privacy settings.
AppLovin matches a user on at least one of aleid, axwrt, client_id, email, phone or user_id. Ads should link straight to your store so the aleid lands in the URL.
AppLovin can’t receive custom events, and post-purchase upsell events aren’t sent to it.
Upstack loads the Axon Pixel for you. If your theme, Google Tag Manager or another app also loads it, remove that copy: two tags with the same Pixel ID can double count events.
The catch
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.
AppLovin Axon Dashboard your pixel Events
Recent events appear here. AppLovin may take a little longer than Upstack to show them.
What changes
AppLovin
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
Events sent to AppLovin carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.
Shopify
Purchases also reach Upstack directly from Shopify, about 10 minutes after the order, so an order still counts when an ad blocker stopped the pixel or the shopper closed the page.
Shopify
Shopify customer IDs, emails and phones are matched against the graph, so repeat buyers are identified across devices.
Setup
App install, no theme edits and no developer. You need admin access to an AppLovin Axon account with an Axon Pixel set up in the AppLovin Dashboard and owner or staff access to Shopify.
01
In the Upstack dashboard, open System, then Data Sources, and click Connect Shopify. Approve the install in your Shopify Admin: Upstack reads products, orders and customers, and writes only its own pixel.
02
In the AppLovin Dashboard, open Account, General, Keys and copy the Event Key. That’s the Pixel ID Upstack needs.
03
Take Axon out of your theme, Google Tag Manager or any other app before Upstack starts loading it.
04
Under Destinations, click New Destination, choose AppLovin Axon and enter the Pixel ID. Turn on Send User Data to include hashed user data, then click Create Configuration.
05
The Events section of your pixel in the AppLovin Axon Dashboard shows recent events. AppLovin may take a little longer than Upstack to show them.
After setup
Upstack shows the AppLovin Axon destination as Healthy.
Your pixel’s Events section in the Axon Dashboard shows recent events.
Clicking one of your live AppLovin ads lands on a URL that carries aleid.
Conversion volume settles after the first 48 hours, while AppLovin adjusts to the new event source.
Troubleshooting
Check the Pixel ID (Event Key) for extra spaces or missing characters, that the destination is Healthy, and that it matches the pixel you’re checking in the Axon Dashboard.
The aleid is missing. Make sure ads link straight to your store, not through a redirect that strips query parameters, and that the Upstack Pixel runs on the landing page.
Missing aleid, anonymous visitors with no email or phone, or a checkout that doesn’t collect email and phone.
Another Axon tag with the same Pixel ID is still loading. Remove it.
FAQ
Connect Shopify, remove any Axon tag you already load, then add the AppLovin Axon destination with your Pixel ID, the Event Key from Account, General, Keys in the AppLovin Dashboard. Upstack then loads the Axon Pixel for you. Most brands are live in under 20 minutes.
No. Upstack loads the Axon Pixel for you once the destination is configured. If you already load Axon through your theme, Google Tag Manager or another app, remove that copy: two tags with the same Pixel ID can double count events.
AppLovin’s match rate depends on how much identity data each event carries. Link AppLovin ads directly to your storefront so the aleid click ID lands in the URL, and make sure your Shopify checkout collects email and phone.
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.
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.
Upstack marks the destination Healthy, and the Events section of the AppLovin Axon Dashboard shows recent events. AppLovin may take a little longer than Upstack to show them, and conversion volume may fluctuate during the first 48 hours.
No. Shopify connects as an app install with no theme edits, and most brands are live in under 20 minutes. Headless storefronts add the Upstack Pixel script instead of the theme app extension.
Not today. AppLovin currently receives events from the browser only, through the Axon Pixel that Upstack loads on your store, and its Tracking Method offers only Browser. Upstack still enriches each event with identity and the aleid click ID before it’s reported.
No. AppLovin can’t receive custom events, and post-purchase upsell events aren’t sent to it.
