How it flows
How a Recharge event reaches Loops. Captured on the server, resolved to a person, then sent.
01 Capture
Captured from Recharge
Bring subscription events into the same resolved customer: new subscriptions, renewals, churn and reactivation.

02 Understand
Resolved to one person before it leaves
Every Recharge 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 Loops
Each Upstack event is mapped to the Loops event below before it is sent.
| Upstack event | Sent to Loops as | Key data on the event |
| Product view | Viewed Product | ProductName, ProductID, Price, ImageURL |
| Add to cart | Added to Cart | ProductName, ProductID, Price, Quantity, CartValue |
| Checkout | Started Checkout | CartValue, ItemCount, CheckoutURL |
| Purchase | Placed Order | OrderID, Revenue, Items, DiscountCodes |
When Upstack identifies a visitor, it attaches the contact’s email and other known properties, and syncs profile properties including name, email and location to Loops.
The catch
Subscription state is not a property of an order.
It changes between them. A CRM fed only order events shows a customer as active long after they canceled.

What changes
What changes when Recharge feeds Loops. Two gains on the Loops side, two on the Recharge side.
Loops
Server-side delivery
Upstack sends events to Loops from its servers only, so ad blockers and browser privacy settings can’t block delivery.
Loops
Identity-resolved events
Events sent to Loops carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.
Recharge
Subscriptions as their own conversion
Send new subscriptions to the ad platforms as a distinct event, not lumped in with one-time orders.
Recharge
Renewals counted properly
Recurring charges are forwarded as real revenue, so LTV reporting reflects what the customer is actually worth.
