API surface

How Stacksync connects to HubSpot.

The connector runs on HubSpot's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
REST API (CRM v3)
Authentication
OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields
Change detection
Records: incremental near-real-time change tracking. Associations: HubSpot has no native association CDC
Rate limits
Request limits vary by subscription tier and API type.

What ships with HubSpot

Connect HubSpot for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every connection.

Real-time

Two-way sync

Changes in HubSpot instantly reflect across connected systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever HubSpot data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single HubSpot record.

Observability

Monitoring

Track your HubSpot sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions.

Use cases

What teams run on the HubSpot connector.

HubSpot is bought by marketing and sales teams at SMB and mid-market companies, often as their first CRM, and positions itself as a unified customer platform spanning marketing, sales, service, and content. Contact and Company records carry the full marketing engagement history, so HubSpot becomes the source of lead and lifecycle data that RevOps and marketing operations need to move into databases, billing systems, and downstream tools.

  • RevOps
  • Marketing operations
  • Data engineering

  1. Two-way sync of Contacts, Companies, and Deals with Postgres or MySQL so product and data teams work on CRM data in SQL.

  2. Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.

  3. Keep HubSpot and Salesforce consistent during a migration or a period of running both CRMs in parallel.

  4. Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.

  5. Sync HubSpot Tickets with an internal support database to unify service reporting across channels.

  6. Two-way sync Contacts, Companies, and Deals with a Postgres database so product and data teams read and write CRM records in SQL instead of coding against the HubSpot API.

FAQ

HubSpot connector FAQ

What can I sync with the HubSpot connector?

HubSpot's core objects — Contact, Company, Deal, Line Item and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to HubSpot?

Via REST API (CRM v3), authenticated with OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields. Changes are detected as follows — records: incremental near-real-time change tracking. Associations: HubSpot has no native association CDC. Stacksync manages rate limits, retries, and schema changes automatically.

Is the HubSpot connector two-way?

Yes. Changes made in HubSpot propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a HubSpot integration take to set up?

Most HubSpot integrations go live in minutes: authenticate HubSpot and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is HubSpot data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. HubSpot data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
