How it flows
How a Recharge event reaches Sendlane. 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 Sendlane
Each Upstack event is mapped to the Sendlane event below before it is sent.
| Upstack event | Sent to Sendlane as | Key data on the event |
| Product view | product-viewed-upstackified | product_id, product_name, product_img_url, variant_id |
| Add to cart | added-to-cart-upstackified | line_items, subtotal, total, currency |
| Checkout | checkout-started-upstackified | checkout_id, line_items, subtotal, total, currency |
| Purchase | order-placed-upstackified | order_id, line_items, total, currency, discounts |
Upstack looks up each contact in Sendlane by email or Sendlane contact ID, and sends the event only if the contact already exists.
The catch
Renewals and new subscriptions look identical coming out of Recharge unless you split them.
Send both into the same flow and long-standing subscribers receive welcome sequences every billing cycle.
Where to check in SendlaneSending you can audit
Sendlane › the contact record
where the event should appear against one person rather than creating a second contact.
What changes
What changes when Recharge feeds Sendlane. Two gains on the Sendlane side, two on the Recharge side.
Sendlane
Server-side delivery
Upstack sends events to Sendlane from its servers only, so ad blockers and browser privacy settings can’t block delivery.
Sendlane
Identity-resolved events
Events sent to Sendlane 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.
