Why teams connect 6sense and Seismic
Run 6sense and Seismic side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
6sense is a read-only source: Stacksync reads its data in real time and delivers it into Seismic, so Seismic always reflects the current state of 6sense — without exports, scripts, or schedulers.
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.
Common use cases
- 01 Feed in-market account lists to sales engagement tools to start sequences automatically.
- 02 Sync 6sense buying stage and intent scores onto CRM accounts so sellers prioritize in-market targets.
- 03 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
- 04 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.
Common sync patterns
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.
Migration with a parallel run
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
What you can sync between 6sense 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.
| 6sense objects | Seismic objects | How this pairing syncs | |
|---|---|---|---|
| Reach Scores Model scores reflecting the level and recency of outreach to an account or contact, used to prioritize follow-up. | Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. | Reach Scores is specific to 6sense and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side. | |
| Accounts Company records enriched with firmographics and intent data, matched to CRM accounts. | Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. | Accounts is specific to 6sense and Reporting Activities to Seismic — each maps to any object or custom field on the other side. | |
| Segments Dynamic account lists built from intent and fit criteria, read out to drive targeting. | Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. | Segments is specific to 6sense and Library Content to Seismic — each maps to any object or custom field on the other side. | |
| Buying Stage Scores Model-predicted stage per account, synced onto CRM records for prioritization. | Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. | Buying Stage Scores is specific to 6sense and Content Versions to Seismic — each maps to any object or custom field on the other side. | |
| Intent Signals Keyword-level research activity used to flag in-market accounts. | Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. | Intent Signals is specific to 6sense and Users to Seismic — each maps to any object or custom field on the other side. | |
| People / Contacts Persona and contact data surfaced for accounts, used to build outreach lists. | User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. | People / Contacts is specific to 6sense and User Groups to Seismic — each maps to any object or custom field on the other side. |
How changes propagate between 6sense 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.
6sense Seismic Interval-based propagation
DetectionStacksync polls 6sense for changes on an incremental schedule, reading only records changed since the previous pass. Polling.
DeliveryEach detected change is written to Seismic through its API, with automatic retries and rate-limit backoff.
Seismic 6sense Sub-second propagation
DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.
Delivery6sense does not accept inbound record writes, so this direction carries requests rather than records: 6sense's output flows back as field updates on the originating Seismic records.
Rate-limit considerations
- 6sense: Subject to the platform's API rate limits, which vary by contracted API package.
- 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.

FAQ
6sense and Seismic integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between 6sense and Seismic — 6sense is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
6sense is a read-only source, so this integration runs one-way: Stacksync reads from 6sense in real time and delivers into Seismic. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for 6sense and Seismic: Where both track pipeline: deal visibility across systems; Post-acquisition consolidation; Migration with a parallel run. Deal stage and value on shared accounts stay visible from either CRM.
-
6sense: REST API. Authentication: API key (token passed in request headers). Seismic: REST Integration APIs and Reporting API v2. Authentication: OAuth 2.0 / OpenID Connect; Bearer token in the Authorization header, via Authorization Code (user context) or client-credentials app-only flows. Stacksync manages authentication, retries, and rate limits on both sides.
-
6sense: Segments are dynamic: accounts enter and leave based on intent and fit criteria, so integrations re-read membership rather than treating lists as static. Seismic: Reporting APIs are ETL-oriented and explicitly not designed for high-frequency, interactive use; they extract batches for a data lake or warehouse. Stacksync's field mapping accounts for these differences between 6sense and Seismic without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means 6sense and Seismic records are not retained after a sync operation.
