Why teams connect HubSpot and Seismic

Run HubSpot and Seismic side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Stacksync syncs Owner, Pipeline, Stages, Audit in HubSpot with Teamsites, LiveSend Links, Digital Sales Rooms, Reporting Activities in Seismic in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.

Common use cases

  • 01 Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • 02 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • 03 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.
  • 04 Sync Library Content metadata and Custom Property Schemas with a DAM or PIM so one taxonomy governs assets across systems.

Common sync patterns

Divisional or regional split

Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

What you can sync between HubSpot and Seismic

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

HubSpot objects Seismic objects How this pairing syncs
Ticket Synced with incremental and full sync per the Stacksync docs. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Ticket is specific to HubSpot and Users to Seismic — each maps to any object or custom field on the other side.
Quote Synced with incremental and full sync per the Stacksync docs. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Quote is specific to HubSpot and User Groups to Seismic — each maps to any object or custom field on the other side.
Goal Synced with incremental and full sync per the Stacksync docs. Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. Goal is specific to HubSpot and Teamsites to Seismic — each maps to any object or custom field on the other side.
Owner Synced with incremental and full sync per the Stacksync docs. LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. Owner is specific to HubSpot and LiveSend Links to Seismic — each maps to any object or custom field on the other side.
Pipeline Synced with incremental and full sync per the Stacksync docs. Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. Pipeline is specific to HubSpot and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side.
Stages Synced with incremental and full sync per the Stacksync docs. Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Stages is specific to HubSpot and Reporting Activities to Seismic — each maps to any object or custom field on the other side.

How changes propagate between HubSpot and Seismic

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

HubSpot Seismic Sub-second propagation

DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.

DeliveryEach detected change is written to Seismic through its API, with automatic retries and rate-limit backoff.

Seismic HubSpot Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

DeliveryEach detected change is written to HubSpot through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • HubSpot: Request limits vary by subscription tier and API type.
  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
