How it flows
How a Loop Subscriptions event reaches Criteo. 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.

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.

03 Activate
Delivered to Criteo
Send resolved conversions to Criteo so retargeting stops re-serving people who already bought, and starts optimizing on the ones who did.

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.
