BigCommerce - Postscript

Postscript

Send every BigCommerce event to Postscript, server-side

Q: How do I check that BigCommerce 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 BigCommerce to Postscript?

Most brands are live in under 20 minutes. Once BigCommerce is connected, 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 BigCommerce event reaches Postscript. Captured on the server, resolved to a person, then sent.

01 Capture

Captured from BigCommerce

Server-side capture of BigCommerce storefront and checkout events, resolved and forwarded downstream.

02 Understand

Resolved to one person before it leaves

Every BigCommerce 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

Storefront browse events and the hosted checkout are effectively two contexts.

Without resolution the same shopper appears in each as a different person.

What changes

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

BigCommerce

Every event, server-side

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