Why teams connect Amazon Aurora and Customer.io

Mirror Customer.io's data into Amazon Aurora 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 Amazon Aurora.

Stacksync mirrors Deliveries / Messages, Newsletters, People, Objects from Customer.io into Databases, Schemas, Tables, Views in Amazon Aurora 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.
  • Two-way sync between Aurora application tables and a CRM so product data and account data stay consistent.
  • Stream row-level changes from Aurora into a warehouse for near-real-time analytics without batch exports.

Read Customer.io with a query

Records from Customer.io are ordinary rows in Amazon Aurora; 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 Amazon Aurora 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 Amazon Aurora, so triggers, jobs, and services can respond in near real time.

What you can sync between Amazon Aurora and Customer.io

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.

Amazon Aurora objects Customer.io objects
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate.
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Campaigns Automated workflows whose membership and metrics can be read via the App API.
Databases Logical databases within a cluster that scope a sync connection. Broadcasts One-off sends to segments or audiences, triggerable via API.
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks.
Tables Relational tables synced bi-directionally at row level. Newsletters Recurring email sends with performance metrics available for reporting syncs.
Views Read-only query-backed sources for downstream syncs. People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs.

How the Amazon Aurora and Customer.io connectors work

Amazon Aurora

Integration surface
MySQL or PostgreSQL wire protocol (SQL); optional RDS Data API over HTTPS
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits

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
