Shopify to Postscript

Forward every Shopify event to Postscript server-side, resolved to a person against a 750M+ device graph — so flows trigger on a known profile rather than an anonymous session.

What changes

What changes when Shopify feeds Postscript.

Server-side delivery

Events reach Postscript through its server API, not the browser — so ad blockers, ITP and consent banners don’t cost you conversions.

Identity-resolved events

Every event sent to Postscript carries a resolved customer, matched against a 750M+ device graph.

100% of conversions, server-side

Orders are captured from Shopify’s servers, so nothing is lost to ad blockers, ITP or a failed browser call.

Recognise returning customers

Shopify customer IDs, emails and phones are matched against the graph, so repeat buyers are identified across devices.

What actually moves

What Shopify carries, and what Postscript needs.

Shopify and Postscript describe a customer with different vocabularies. This is the mapping Upstack applies on the way through — the left column is what Shopify can put on an event, the right is what Postscript can actually use.

Shopify sends

order_id
Shopify order and checkout token
email / phone
customer contact from checkout
customer_id
Shopify customer record, if they have one
line_items
products, variants and quantities
total / subtotal / discount
order economics
customer_type
new or returning, resolved before send

Postscript receives

phone
subscriber key
email
profile matching
order / cart properties
automation triggers

Sending you can audit

How you know it is working.

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

  • Per-profile inspection

    Trace any event to the profile it resolved to, and see why.
  • Deduplication

    One order produces one event, so a single purchase cannot trigger the same flow twice.
  • Bot and fraud filtering

    Automated traffic never becomes a profile, so list quality and deliverability are not paying for it.
