Why teams connect Freshsales and Seismic
Run Freshsales 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 Products, Contacts, Accounts, Deals in Freshsales with LiveSend Links, Digital Sales Rooms, Reporting Activities, Library Content 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 Sync deals into a data warehouse for pipeline reporting alongside product usage data.
- 02 Push product-qualified leads from the warehouse into Freshsales as contacts with lifecycle stages set.
- 03 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
- 04 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
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 Freshsales 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.
| Freshsales objects | Seismic objects | How this pairing syncs | |
|---|---|---|---|
| Products Catalog items attached to deals for line-level revenue data. | User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. | Products is specific to Freshsales and User Groups to Seismic — each maps to any object or custom field on the other side. | |
| Contacts Person records carrying lifecycle stages; the main entity for two-way CRM syncs. | Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. | Contacts is specific to Freshsales and Teamsites to Seismic — each maps to any object or custom field on the other side. | |
| Accounts Company records kept aligned with billing, ERP, and warehouse tables. | LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. | Accounts is specific to Freshsales and LiveSend Links to Seismic — each maps to any object or custom field on the other side. | |
| Deals Pipeline records synced to a warehouse for revenue reporting. | Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. | Deals is specific to Freshsales and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side. | |
| Tasks Rep to-dos created from external triggers or synced for productivity reporting. | Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. | Tasks is specific to Freshsales and Reporting Activities to Seismic — each maps to any object or custom field on the other side. | |
| Appointments Scheduled meetings readable for activity analytics. | Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. | Appointments is specific to Freshsales and Library Content to Seismic — each maps to any object or custom field on the other side. |
How changes propagate between Freshsales 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.
Freshsales Seismic Sub-second propagation
DetectionFreshsales notifies Stacksync of record changes through webhook events. Polling with updated-at filters through views.
DeliveryEach detected change is written to Seismic through its API, with automatic retries and rate-limit backoff.
Seismic Freshsales 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 Freshsales through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Freshsales: Subject to per-account API rate limits that vary by Freshworks plan.
- 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.
