Loop Subscriptions to Criteo

Forward every Loop Subscriptions event to Criteo server-side, resolved to a person against a 750M+ device graph — with restored click IDs, deduplicated conversions and delivery you can audit.

What changes

What changes when Loop Subscriptions feeds Criteo.

Server-side delivery

Events reach Criteo through its server API, not the browser — so ad blockers, ITP and consent banners don’t cost you conversions.

Identity-resolved events

Every event sent to Criteo carries a resolved customer, matched against a 750M+ device graph.

Every event, server-side

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

One setup, every destination

Connect Loop Subscriptions once and forward to every ad platform, email tool and warehouse you run.

What actually moves

What Loop Subscriptions carries, and what Criteo needs.

Loop Subscriptions and Criteo describe a customer with different vocabularies. This is the mapping Upstack applies on the way through — the left column is what Loop Subscriptions can put on an event, the right is what Criteo can actually use.

Loop Subscriptions sends

subscription_id
the Loop subscription across its whole life
email / phone
subscriber contact
event_type
renewal, swap, skip, pause, cancel or save
line_items
products after any swap
total / interval
charge amount and billing cadence
customer_type
new or returning, resolved before send

Criteo receives

hashed email
match the buyer for suppression and matching
criteo_click_id
credit the click
event_id
dedupe against the OneTag
value / currency
value-based bidding
product ids
suppress the exact items already bought

Delivery you can audit

How you know it is working.

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.

  • Per-event inspection

    Every conversion is inspectable from the moment it fires to the moment the platform confirms it.
  • Deduplication

    Browser and server copies of the same purchase collapse on event ID, so nothing is counted twice.
  • Bot and fraud filtering

    Automated traffic never reaches the model, because what you keep out of the training set matters as much as what goes in.
