Why teams connect Seismic and Twenty CRM
Run Seismic and Twenty CRM 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 Content Versions, Users, User Groups, Teamsites in Seismic with Workspace Members, People, Companies, Opportunities in Twenty CRM 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 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
- 02 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.
- 03 Sync Opportunities into a finance system to keep revenue forecasts current.
- 04 Mirror support tickets or tasks between Twenty and an operations tool.
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.

How changes propagate between Seismic and Twenty CRM
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.
Seismic Twenty CRM 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 Twenty CRM through its API, with automatic retries and rate-limit backoff.
Twenty CRM Seismic Sub-second propagation
DetectionTwenty CRM notifies Stacksync of record changes through webhook events. Webhooks on record create, update, and delete events, or polling on record update timestamps.
DeliveryEach detected change is written to Seismic through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- 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.
- Twenty CRM: Subject to the platform's API rate limits; self-hosted deployments control their own limits.

FAQ
Seismic and Twenty CRM integration FAQ

Stacksync's field mapping accounts for these differences between Seismic and Twenty CRM without custom code.
