Custom stack to HubSpot

HubSpot
Push identity-resolved events and contacts into HubSpot so CRM records match what actually happened.
HubSpot integrationWhat changes
What changes when Custom stack feeds HubSpot.
Server-side delivery
Events reach HubSpot 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 HubSpot carries a resolved customer, matched against a 750M+ device graph.
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.
The same event schema
Custom events are resolved, filtered and forwarded exactly like a Shopify order.
What actually moves
What Custom stack carries, and what HubSpot needs.
Custom stack and HubSpot describe a customer with different vocabularies. This is the mapping Upstack applies on the way through — the left column is what Custom stack can put on an event, the right is what HubSpot can actually use.
Custom stack sends
- event_name
- whatever you choose to call it
- user identifiers
- any of email, phone, external ID
- value / currency
- if the event carries revenue
- custom properties
- any attribute in your own schema
HubSpot receives
- the contact key
- lifecycle properties
- stage and pipeline
- deal / order value
- revenue on the record
Records you can audit
How you know it is working.
A CRM is only as trustworthy as its worst duplicate. These controls exist so the record reflects the person.
Per-record inspection
Trace any property back to the event that set it.Deduplication
One person, one record, across devices and identifiers.Bot and fraud filtering
Automated traffic never becomes a contact.
Where to check in HubSpot
HubSpotthe contact timeline, and the duplicate-management view, which should stop growing.
