Why teams connect Attio and Clari
Run Attio and Clari 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 People, Companies, Users, Deals in Attio with Account field extensions, Opportunity field extensions, Audit Events, Forecast in Clari 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 companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.
- 02 Write product usage and enrichment data into Attio attributes so GTM teams work from live account signals.
- 03 Stream Audit Events into a reporting database to monitor forecast-submission changes and user activity for compliance.
- 04 Pull Activity (Capture) meetings and emails, mapped to their accounts and opportunities, into a database for coverage and engagement analysis.
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 Attio and Clari
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 | Clari objects | How this pairing syncs | |
|---|---|---|---|
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Account field extensions External data points written onto Account records through the ingest API in initial or incremental mode; requires an apikey plus a partnerkey. | Deals is specific to Attio and Account field extensions to Clari — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Opportunity field extensions Warehouse-computed fields pushed onto Opportunity records via the ingest API; up to 100 records per request or 10MB bulk files. | Workspaces is specific to Attio and Opportunity field extensions to Clari — 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. | Audit Events User edits and system events exported with filtering by actor, session, and date range; read-only feed for change tracking and compliance. | Custom objects is specific to Attio and Audit Events to Clari — each maps to any object or custom field on the other side. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Forecast Exported per forecast tab and fiscal period via async jobs; includes submitted forecast calls, updates, manager adjustments, and CRM totals. Read-only. | People is specific to Attio and Forecast to Clari — 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. | Quota Quota and quota-history values exported alongside forecast data, scoped by fiscal quarter; read-only, useful for warehouse attainment reporting. | Companies is specific to Attio and Quota to Clari — each maps to any object or custom field on the other side. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Opportunities Retrieved synchronously by ID from GET /opportunity (up to 100 IDs per call) with Clari CRM scoring and field-change history; read-only, mirroring the CRM opportunity Clari sits on. | Users is specific to Attio and Opportunities to Clari — each maps to any object or custom field on the other side. |
How changes propagate between Attio and Clari
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 Clari 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 Clari through its API, with automatic retries and rate-limit backoff.
Clari Attio Interval-based propagation
DetectionStacksync polls Clari for changes on an incremental schedule, reading only records changed since the previous pass. Polling — reads run as asynchronous export jobs (submit export, poll job status, download results).
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.
- Clari: Max 3 concurrent exports and roughly 1000 exports per rolling 30-day org window; ingestion capped at 100 requests/sec per API token.

FAQ
Attio and Clari integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Clari: authenticate both systems, choose the objects to sync (such as Attio's Deals and Workspaces), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 Attio and Clari records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Attio and Clari connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Attio–Clari integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Attio and Clari. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. On Clari: Polling — reads run as asynchronous export jobs (submit export, poll job status, download results); the ingest API supports an incremental mode for regular field updates. No webhooks. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Attio side: People, Companies, Users, Deals, plus custom fields where Attio exposes them. On the Clari side: Account field extensions, Opportunity field extensions, Audit Events, Forecast. Stacksync auto-detects both schemas and converts types between the two systems.
