Checkout Champ - Postscript

Postscript

Send Checkout Champ funnel events to Postscript

Q: How do I check that Checkout Champ events are reaching Postscript?

Open Postscript › Subscribers › the individual subscriber's activity feed.

Q: Can one purchase trigger the same flow twice?

No. One order produces one event, so a single purchase cannot trigger the same flow twice.

Q: How long does it take to connect Checkout Champ to Postscript?

Most brands are live in under 20 minutes. Once Checkout Champ events reach Upstack, every destination receives the same resolved events, Postscript included.

Each event is resolved to a person against a 750M+ device graph before it reaches Postscript, so flows trigger on a known profile rather than an anonymous session.

How it flows

How a Checkout Champ event reaches Postscript. Captured on the funnel page, resolved to a person, then sent.

01 Capture

Captured from Checkout Champ

Track Checkout Champ funnels with the Upstack Pixel, from the first page to the completed order, and send each event to your destinations resolved against the same identity graph.

02 Understand

Resolved to one person before it leaves

Every Checkout Champ 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.
DeduplicationOne order produces one event, so a single purchase cannot trigger the same flow twice.
Bot and fraud filteringAutomated traffic never becomes a profile, so list quality and deliverability are not paying for it.

Messaging mistakes are expensive and public. These controls exist so a flow never fires against a profile that should not have received it.

03 Activate

The catch

Funnel checkouts sit outside the main storefront, so retention flows built around storefront events simply do not fire for them.

What changes

What changes when Checkout Champ feeds Postscript. Two gains on the Postscript side, two on the Checkout Champ side.

Postscript

Server-side delivery

Events reach Postscript through its server API rather than the browser, so ad blockers and ITP don’t cost you conversions.

Postscript

Identity-resolved events

Events sent to Postscript carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.

Checkout Champ

Every funnel step tracked

Page views, checkout starts, add-to-carts, shipping and payment steps and completed orders fire from the funnel, so your platforms see the whole path rather than the landing page alone.
