Why teams connect Affinity and Seismic

Run Affinity 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 Opportunities, Field Values, Notes, Interactions in Affinity with User Groups, Teamsites, LiveSend Links, Digital Sales Rooms 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 deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.
  • 02 Push enrichment data computed elsewhere into Affinity field values on list entries.
  • 03 Sync Library Content metadata and Custom Property Schemas with a DAM or PIM so one taxonomy governs assets across systems.
  • 04 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.

Common sync patterns

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.

Where both track pipeline: deal visibility across systems

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

What you can sync between Affinity 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.

Affinity objects Seismic objects How this pairing syncs
Organizations Company records matched to accounts in other systems by domain. Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. Organizations is specific to Affinity and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side.

Notes is specific to Affinity and Content Versions to Seismic — each maps to any object or custom field on the other side.
Interactions Automatically captured emails and meetings, read for activity reporting. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Interactions is specific to Affinity and Users to Seismic — each maps to any object or custom field on the other side.

How changes propagate between Affinity 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.

Affinity Seismic Sub-second propagation

DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.

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

Seismic Affinity 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 Affinity through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Affinity: 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.
