Loop Subscriptions - Taboola

Send every Loop Subscriptions event to Taboola, server-side

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: How do I check that Loop Subscriptions events are reaching Taboola?

Once Upstack marks the destination Healthy, open Tracking, Test Events in Taboola Backstage. Taboola’s API returns 204 for every request, even invalid ones, so Test Events is the only way to confirm events are processed.

Q: How long does it take to connect Loop Subscriptions to Taboola?

Most brands are live in under 20 minutes. Once Loop Subscriptions is connected, every destination receives the same resolved events, Taboola included.

Each event is resolved to a person against a 750M+ device graph before it reaches Taboola, with restored click IDs, deduplicated conversions and delivery you can audit.

How it flows

How a Loop Subscriptions event reaches Taboola. Captured on the server, resolved to a person, then sent.

01 Capture

Captured from Loop Subscriptions

Capture Loop Subscriptions events server-side (new subscriptions, renewals, swaps and cancellations), each as what it actually is.

See the Loop Subscriptions integration

02 Understand

Resolved to one person before it leaves

Every Loop Subscriptions 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

Resolved before it is sent

IdentityMatched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer.
customer_typeNew or returning, resolved before send.
DeduplicationBrowser and server copies of a purchase are matched on its order ID, so it is counted once.
Bot and fraud filteringAutomated traffic never reaches the model, because what you keep out of the training set matters as much as what goes in.

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

Delivered to Taboola

Forward resolved conversions to Taboola through its server-side API, so discovery traffic gets credited for the purchases it actually produced.

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

Swaps, pauses and saves produce state changes with no order attached.

Ad platforms receiving only orders see a paused subscriber as churned and start bidding to re-acquire someone who is still a customer.

What changes

What changes when Loop Subscriptions feeds Taboola. Two gains on the Taboola side, two on the Loop Subscriptions 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.

Loop Subscriptions

Storefront and checkout events are captured from Loop Subscriptions on the server, independent of the browser.
