Why teams connect Kustomer and Supabase
Treat Kustomer like part of your database: its records live in Supabase 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 Supabase, where it can be queried and joined like everything else.
Stacksync mirrors Custom Objects (Klasses), Users, Teams, Tags from Kustomer into Row Level Security Policies, JSONB Columns, Database Functions, Storage Object Metadata in Supabase with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kustomer 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
- 01 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- 02 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
- 03 Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns
- 04 Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
Common sync patterns
Internal tools without API code
Back-office apps read and write the synced tables; Stacksync handles the Kustomer API, limits, and retries.
Trigger workflows from CRM changes
Field and stage updates in Kustomer arrive as row changes in Supabase, ready to drive jobs and notifications.
Query the CRM like a database
Accounts, contacts, and custom objects from Kustomer become tables in Supabase you can join with application data directly.
What you can sync between Kustomer and Supabase
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.
| Kustomer objects | Supabase objects | How this pairing syncs | |
|---|---|---|---|
| Notes Internal annotations carry context alongside synced conversations. | Database Functions Postgres functions that can transform or validate synced rows. | Notes is specific to Kustomer and Database Functions to Supabase — each maps to any object or custom field on the other side. | |
| Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Storage Object Metadata File metadata rows that can be joined to synced application data. | Customers is specific to Kustomer and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side. | |
| Conversations Support threads across channels sync outward for analytics and CRM context. | Tables Standard Postgres tables; the primary two-way sync target. | Conversations is specific to Kustomer and Tables to Supabase — each maps to any object or custom field on the other side. | |
| Messages Individual messages within conversations support full-thread replication. | Views Read-side projections exposed to outbound syncs. | Messages is specific to Kustomer and Views to Supabase — each maps to any object or custom field on the other side. | |
| Companies Organization records group customers and map to CRM accounts. | Schemas Namespaces (public and custom) that scope sync access. | Companies is specific to Kustomer and Schemas to Supabase — each maps to any object or custom field on the other side. | |
| Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | auth.users Managed authentication users, often mirrored into CRM or support systems. | Custom Objects (Klasses) is specific to Kustomer and auth.users to Supabase — each maps to any object or custom field on the other side. |
How changes propagate between Kustomer and Supabase
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.
Kustomer Supabase Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is applied to Supabase as a row-level write, with types converted between the two schemas.
Supabase Kustomer Sub-second propagation
DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Kustomer: Subject to the platform's API rate limits.
- Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

FAQ
Kustomer and Supabase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Kustomer and Supabase: authenticate both systems, choose the objects to sync (such as Kustomer's Notes and Customers), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Kustomer: Custom object types are called Klasses, and they are the standard mechanism for landing external data like orders and subscriptions where agents work. Supabase: Every Supabase project is a full PostgreSQL database, so standard Postgres drivers, SQL tooling, and log-based CDC apply directly. Stacksync's field mapping accounts for these differences between Kustomer and Supabase without custom code.
-
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 Kustomer and Supabase records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Kustomer and Supabase connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Kustomer–Supabase integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Kustomer and Supabase. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Kustomer: Outbound webhooks on record events, plus polling for backfill. On Supabase: Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime; database webhooks can also fire on row changes. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
