Why teams connect Customer.io and Oracle DB

Mirror Customer.io's data into Oracle DB 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 Oracle DB.

Stacksync mirrors Events, Segments, Campaigns, Broadcasts from Customer.io into Partitions, JSON columns, Tables, Views in Oracle DB 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

  • Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Log-based replication of order and inventory tables into an analytics warehouse instead of nightly batch dumps.
  • Expose a curated subset of an on-prem Oracle ERP schema to cloud tools by syncing it to a managed Postgres.

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 Oracle DB; 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 Oracle DB and Stacksync propagates the change into Customer.io, replacing custom integration code.

What you can sync between Customer.io and Oracle DB

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 Oracle DB objects
Broadcasts One-off sends to segments or audiences, triggerable via API. Partitions Physical subdivisions relevant when replicating high-volume tables
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. JSON columns Document data stored in the converged engine and synced alongside relational rows
Newsletters Recurring email sends with performance metrics available for reporting syncs. Tables The primary read/write surface for row-level sync over SQL
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Views Curated read-only projections exposed to downstream consumers
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Materialized views Precomputed results occasionally used as stable replication sources
Events Behavioral events sent via the Track API that trigger campaigns. Schemas Per-user namespaces that scope sync permissions and object visibility

How the Customer.io and Oracle DB 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

Oracle DB

Integration surface
SQL wire protocol (Oracle Net) via JDBC, ODBC, and native OCI drivers
Authentication
database username and password; wallets, Kerberos, and directory-based authentication in enterprise setups
Change detection
log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling
Capabilities
read · write · CDC
Rate limits
throughput bounded by database resources rather than API quotas
