Why teams connect Customer.io and TiDB

Mirror Customer.io's data into TiDB 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 TiDB.

Stacksync mirrors Campaigns, Broadcasts, Deliveries / Messages, Newsletters from Customer.io into Sequences, Databases, Tables, Views in TiDB 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

  • Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas
  • Two-way sync between TiDB tables and SaaS tools so operational edits made in either system converge

Read Customer.io with a query

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

Automate Customer.io from your codebase

Write to the synced tables in TiDB and Stacksync propagates the change into Customer.io, replacing custom integration code.

React to changes as they happen

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

What you can sync between Customer.io and TiDB

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 TiDB objects
Campaigns Automated workflows whose membership and metrics can be read via the App API. Views Logical views for shaping reads before syncing outward.
Broadcasts One-off sends to segments or audiences, triggerable via API. Columns MySQL-compatible types mapped to fields in the paired system.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Indexes Secondary indexes that keep incremental sync queries efficient.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Sequences Server-side ID generation relevant when external systems write rows.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Databases MySQL-style schemas addressed by any MySQL-compatible client.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.

How the Customer.io and TiDB 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

TiDB

Integration surface
MySQL wire protocol (SQL)
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Log-based CDC via TiCDC, which captures row changes from TiKV and streams them to downstream sinks; polling also works
Capabilities
read · write · CDC
Rate limits
Throughput scales with cluster size rather than fixed API quotas
