Why teams connect Firebase and Kommo

Treat Kommo like part of your database: its records live in Firebase 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 Firebase, where it can be queried and joined like everything else.

Stacksync mirrors Companies, Pipelines & Statuses, Tasks, Notes from Kommo into Realtime Database Nodes, Authentication Users, Cloud Storage Objects, Cloud Functions Triggers in Firebase 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

  • Push web form and product signups into Kommo pipelines as they are submitted so messenger-based follow-up starts quickly
  • Keep customer records consistent between Kommo and invoicing or ERP systems
  • Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
  • Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Firebase 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.

Trigger workflows from CRM changes

Field and stage updates in Kommo arrive as row changes in Firebase, ready to drive jobs and notifications.

What you can sync between Firebase 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.

Firebase objects Kommo objects
Subcollections Nested collections under documents, typically flattened into related tables during sync. Users Account users map lead ownership to people in other systems.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Chats Messenger conversations from WhatsApp, Instagram, and other channels attach to leads and contacts.
Authentication Users User accounts read into CRMs and warehouses for customer records. Leads The central pipeline record; external signups and form fills sync in as leads.
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Contacts Person records sync with other CRMs and databases for a shared contact file.
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Companies Organization records map to accounts in ERPs and invoicing tools.
Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. Pipelines & Statuses Stage definitions structure lead progress and drive stage-change syncs to reporting tools.
