Why teams connect AWS S3 and Kommo

Sync Kommo 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. Users, Chats, Leads, Contacts from Kommo land in AWS S3 as live tables, updated within seconds, and columns computed in AWS S3 write back to fields in Kommo. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Mirror pipeline stage changes into BI tools for forecasting
  • Route leads that originate in WhatsApp or Instagram conversations into other systems of record
  • Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.
  • Trigger incremental sync runs from S3 event notifications when new files land in a prefix.

Cleanup that sticks

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

CRM analytics on live data

Accounts, contacts, and activity from Kommo are queryable in AWS S3 moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

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

What you can sync between AWS S3 and Kommo

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 Kommo objects
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Contacts Person records sync with other CRMs and databases for a shared contact file.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Companies Organization records map to accounts in ERPs and invoicing tools.
Object Metadata System and user-defined metadata read alongside object contents. Pipelines & Statuses Stage definitions structure lead progress and drive stage-change syncs to reporting tools.
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Tasks Follow-up records keep rep activity consistent across systems.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Notes Free-text and system notes attach context to synced leads and contacts.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Custom Fields Per-entity custom fields hold data written from external databases and enrichment.
