Why teams connect AWS S3 and Clari

Sync Clari into AWS S3 continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Forecast, Quota, Opportunities, Activity (Capture) from Clari land in AWS S3 as live tables, updated within seconds, and columns computed in AWS S3 write back to fields in Clari. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Write warehouse-computed health scores and usage metrics onto Clari Opportunity records as field extensions via the ingest API so deal reviews show product signals.
  • 02 Enrich Clari Account records with firmographic or billing data points through the ingest API in incremental mode.
  • 03 Archive change history from ongoing syncs as timestamped files for audit and replay.
  • 04 Ingest partner or vendor file drops (CSV, JSON, Parquet) from a bucket into a database or CRM as records.

Common sync patterns

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in AWS S3 appear as fields in Clari, where the people working accounts actually see them.

A single customer view

Join Clari's relationship data with billing, product, and support data in AWS S3 to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in AWS S3 can be written back, so warehouse-side cleanup actually fixes the CRM.

What you can sync between AWS S3 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.

AWS S3 objects Clari objects How this pairing syncs
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Quota Quota and quota-history values exported alongside forecast data, scoped by fiscal quarter; read-only, useful for warehouse attainment reporting. Object Versions is specific to AWS S3 and Quota to Clari — each maps to any object or custom field on the other side.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. 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. Event Notifications is specific to AWS S3 and Opportunities to Clari — each maps to any object or custom field on the other side.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Activity (Capture) Meetings, emails, and attachments captured by Clari and mapped to accounts and opportunities; exported read-only via async activity jobs. Access Points is specific to AWS S3 and Activity (Capture) to Clari — each maps to any object or custom field on the other side.
Multipart Uploads The mechanism used to write large export files reliably. 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. Multipart Uploads is specific to AWS S3 and Account field extensions to Clari — each maps to any object or custom field on the other side.
Buckets Top-level containers a sync targets; region and policy are set at this level. Opportunity field extensions Warehouse-computed fields pushed onto Opportunity records via the ingest API; up to 100 records per request or 10MB bulk files. Buckets is specific to AWS S3 and Opportunity field extensions to Clari — each maps to any object or custom field on the other side.
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Audit Events User edits and system events exported with filtering by actor, session, and date range; read-only feed for change tracking and compliance. Objects is specific to AWS S3 and Audit Events to Clari — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 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.

AWS S3 Clari Sub-second propagation

DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.

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

Clari AWS S3 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 AWS S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
  • Clari: Max 3 concurrent exports and roughly 1000 exports per rolling 30-day org window; ingestion capped at 100 requests/sec per API token.

Clari

Integration surface
REST APIs on api.clari.com - Export API (v4, asynchronous bulk jobs for forecast, quota, activity, and audit) and Ingest API (v2, field extensions); Opportunity reads are synchronous via GET /opportunity
Authentication
API token in the apikey header, generated per user in Settings; ingest/partner endpoints also require a partnerkey header, and Copilot endpoints require X-Api-Key and X-Api-Password
Change detection
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.
