Why teams connect Customer.io and TimescaleDB

Mirror Customer.io's data into TimescaleDB so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Customer.io through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in TimescaleDB.

Stacksync mirrors Deliveries / Messages, Newsletters, People, Objects from Customer.io into Continuous Aggregates, Regular PostgreSQL Tables, Views, Schemas in TimescaleDB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Customer.io, so the tool and the database never disagree.

Common use cases

  • Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
  • Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • Replicate subscription and billing events from operational Postgres tables into Timescale hypertables for time-series analysis.
  • Keep device or asset reference tables bi-directionally in sync between TimescaleDB and an ERP.

React to changes as they happen

Updates in Customer.io arrive as row changes in TimescaleDB, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Customer.io with a query

Records from Customer.io are ordinary rows in TimescaleDB; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Customer.io and TimescaleDB

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.

Customer.io objects TimescaleDB objects
Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Schemas Postgres namespaces used to separate synced datasets by team or environment.
Campaigns Automated workflows whose membership and metrics can be read via the App API. Hypertables Time-partitioned tables that hold the main time-series data; the primary read and write target in syncs.
Broadcasts One-off sends to segments or audiences, triggerable via API. Chunks Time-bounded partitions of a hypertable; syncs read and write through the parent hypertable and never address chunks directly.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Continuous Aggregates Incrementally maintained rollups that serve as pre-aggregated read sources for downstream systems.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Regular PostgreSQL Tables Relational reference data such as devices, tenants, or accounts synced alongside the series data.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Views Standard SQL views used to shape or filter data for consumers.

Handle millions of events per minute without losing a single Customer.io or TimescaleDB record.

Observability

Monitoring

Track your Customer.io ⇄ TimescaleDB sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Customer.io and TimescaleDB.

How the Customer.io and TimescaleDB connectors work

Customer.io

Integration surface
REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
Authentication
Basic auth with site ID and API key for the Track API; bearer token for the App API
Change detection
Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
Capabilities
read · write · webhooks
Rate limits
Subject to per-API rate limits documented by Customer.io

TimescaleDB

Integration surface
SQL wire protocol (PostgreSQL)
Authentication
Database credentials
Change detection
Log-based capture via PostgreSQL logical decoding where the deployment allows it — hypertable changes surface on the underlying chunk tables and must be remapped to the parent — or timestamp-based polling on time columns; regular Postgres tables replicate through standard logical replication
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by database resources and connection limits.
