How it flows
How a Custom stack event reaches Gorgias. Captured on the server, resolved to a person, then sent.
01 Capture
Captured from Custom stack
Not on the list? Send events to Upstack from any stack over webhook or direct post, with the same schema and the same resolution.

02 Understand
Resolved to one person before it leaves
Every Custom stack event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.

The catch
Post-purchase tools expect an order shape.
A custom event has to be mapped to one, or the request has nothing to reference.

What changes
What changes when Custom stack feeds Gorgias. Two gains on the Gorgias side, two on the Custom stack side.
Gorgias
Server-side delivery
Events reach Gorgias through its server API rather than the browser, so ad blockers and ITP don’t cost you conversions.
Gorgias
Identity-resolved events
Events sent to Gorgias carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.
Custom stack
Any stack, any framework
Headless, custom checkout, native app or a platform we haven’t listed: if it can make an HTTP request, it can send to Upstack.
Custom stack
The same event schema
Custom events are resolved, filtered and forwarded exactly like a Shopify order.
Setup
Post directly from your backend so nothing depends on the browser.
Connect Custom stack once and every destination, Gorgias included, is forwarded the same resolved events.
