Why teams connect HubSpot and Zendesk

Sync what happens in Zendesk with the customer records in HubSpot, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Zendesk holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Ticket Forms, Tickets, Tickets Comments, Users in Zendesk to Company, Deal, Line Item, Product in HubSpot with bi-directional, real-time sync. Activity and record changes in Zendesk update the matching contact or account in HubSpot, and CRM data flows the other way wherever Zendesk can store and use it.

Common use cases

  • Sync tickets, users, and organizations into Postgres so support analytics run on SQL instead of repeated API pulls.
  • Write CRM account tier, owner, and renewal data onto Zendesk organizations and ticket fields so agents see context in the ticket.
  • Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.

Where Zendesk handles support or shared inboxes

Tickets and conversations attach to the right contact and account in HubSpot, so sales sees open issues before the next call.

Where Zendesk supplies contact or company data

Enriched fields land directly on records in HubSpot, and refreshes keep them from going stale.

Where Zendesk can store CRM context: fields kept current

Owner, lifecycle stage, or account details from HubSpot sync into Zendesk, so people working there have the context without switching tools.
