How it flows
How a Skio event reaches Taboola. Captured on the server, resolved to a person, then sent.
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.

Which events reach Taboola
Each Upstack event is mapped to the Taboola event below before it is sent.
| Upstack event | Sent to Taboola as | Key data on the event |
| Page view | page_view | None beyond the click ID |
| Product view | view_content | None beyond the click ID |
| Add to cart | add_to_cart | quantity |
| Checkout | start_checkout | revenue, currency |
| Purchase | make_purchase | revenue, currency, orderid |
Taboola does not support matching on hashed email, phone or other personal data: attribution relies solely on the tblci click ID captured from ad clicks. Events without a click ID are skipped.
The catch
A first charge is an acquisition and a renewal is not, but both arrive as purchases.
Sending renewals as conversions is the single most common way a subscription brand teaches Meta to re-buy its existing subscribers.

What changes
What changes when Skio feeds Taboola. Two gains on the Taboola side, two on the Skio side.
Taboola
Server-side delivery
By default Upstack sends events to Taboola from its servers as well as through the Taboola tag, so an event an ad blocker or browser privacy setting stops in the browser still arrives from the server.
Taboola
Identity-resolved events
Events sent to Taboola 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 Taboola.
Will my events be counted twice if I run both the pixel and server-side?
No. When the browser pixel and S2S report the same event, Taboola keeps the S2S event and deduplicates the pixel event. Including an orderid on purchase events further improves deduplication.
Do event names need to match exactly?
Yes. Event names are case-sensitive and must exactly match the conversion name configured in Taboola Realize. Upstack sends lowercase snake_case names such as make_purchase and add_to_cart.
Which events does Taboola receive?
PageView as page_view, ViewContent as view_content, AddToCart as add_to_cart, InitiateCheckout as start_checkout and Purchase as make_purchase.
Which customer parameters are sent to Taboola?
Taboola does not support matching on hashed email, phone or other personal data: attribution relies solely on the tblci click ID captured from ad clicks. Events without a click ID are skipped.
