Why teams connect Attio and Seismic
Run Attio 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 Workspaces, Custom objects, People, Companies in Attio with Library Content, Content Versions, Users, User Groups 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 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- 02 Run a two-way dual-run when migrating to Attio from another CRM.
- 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
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.
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.
What you can sync between Attio 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.
| Attio objects | Seismic objects | How this pairing syncs | |
|---|---|---|---|
| Users 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. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. | Workspaces is specific to Attio and Content Versions to Seismic — each maps to any object or custom field on the other side. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. | Custom objects is specific to Attio and User Groups to Seismic — each maps to any object or custom field on the other side. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. | People is specific to Attio and Teamsites to Seismic — each maps to any object or custom field on the other side. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. | Companies is specific to Attio and LiveSend Links to Seismic — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. | Deals is specific to Attio and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side. |
How changes propagate between Attio 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.
Attio Seismic Sub-second propagation
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is written to Seismic through its API, with automatic retries and rate-limit backoff.
Seismic Attio 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 Attio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Attio: Subject to the platform's published API rate limits.
- 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
Attio and Seismic integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Seismic: authenticate both systems, choose the objects to sync (such as Attio's Users and Workspaces), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. On Seismic: Webhooks for content, version, user, group, workflow, DSR, and LiveSend events; the Reporting API v2 is polled for batch historical extracts (ETL-oriented, not high-frequency). Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Attio side: Workspaces, Custom objects, People, Companies, plus custom fields where Attio exposes them. On the Seismic side: Library Content, Content Versions, Users, User Groups. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Attio and Seismic: Post-acquisition consolidation; Migration with a parallel run; Divisional or regional split. Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
