Why teams connect Customer.io and IBM Informix

Mirror Customer.io's data into IBM Informix 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 IBM Informix.

Stacksync mirrors Events, Segments, Campaigns, Broadcasts from Customer.io into Stored procedures, Logical logs, Databases, Tables in IBM Informix 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

  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • Sync sensor and meter readings stored in Informix TimeSeries structures to analytics platforms.
  • Run a two-way sync between an Informix-backed retail or POS application and a CRM so store data reaches go-to-market teams.

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 IBM Informix; 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 IBM Informix and Stacksync propagates the change into Customer.io, replacing custom integration code.

What you can sync between Customer.io and IBM Informix

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 IBM Informix objects
Broadcasts One-off sends to segments or audiences, triggerable via API. Stored procedures Server-side logic sometimes invoked as part of write paths.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Logical logs The transaction log that Informix's CDC interface reads committed changes from.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Databases Top-level containers that scope a sync connection.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Tables Relational tables mapped directly to sync targets.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Rows The unit of read and write, keyed by primary key.
Events Behavioral events sent via the Track API that trigger campaigns. Views Read-only projections used to shape outbound data.

How the Customer.io and IBM Informix 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

IBM Informix

Integration surface
SQL over JDBC/ODBC drivers; DRDA connectivity is also supported
Authentication
Database credentials
Change detection
Informix's Change Data Capture API reading committed changes from logical logs; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by server resources and session limits rather than an API quota.
