Why teams connect Kommo and PostgreSQL

Treat Kommo like part of your database: its records live in PostgreSQL as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in PostgreSQL, where it can be queried and joined like everything else.

Stacksync mirrors Users, Chats, Leads, Contacts from Kommo into Schemas, Columns, Primary and Unique Keys, JSONB Columns in PostgreSQL with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kommo with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Keep customer records consistent between Kommo and invoicing or ERP systems
  • Mirror pipeline stage changes into BI tools for forecasting
  • Consolidate data from several microservice databases into one operational Postgres store
  • Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts

Query the CRM like a database

Accounts, contacts, and custom objects from Kommo become tables in PostgreSQL you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to PostgreSQL sync onto the matching records in Kommo, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Kommo API, limits, and retries.

What you can sync between Kommo and PostgreSQL

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.

Kommo objects PostgreSQL objects
Notes Free-text and system notes attach context to synced leads and contacts. Sequences Generate surrogate keys for rows created by inbound syncs.
Custom Fields Per-entity custom fields hold data written from external databases and enrichment. Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields.
Users Account users map lead ownership to people in other systems. Tables The primary sync target; rows map one-to-one to records in connected SaaS systems.
Chats Messenger conversations from WhatsApp, Instagram, and other channels attach to leads and contacts. Views Read-side projections used to expose joined or filtered data to a sync.
Leads The central pipeline record; external signups and form fills sync in as leads. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Contacts Person records sync with other CRMs and databases for a shared contact file. Schemas Namespaces that scope which tables a sync reads and writes.
