Why teams connect Customer.io and IBM Db2

Mirror Customer.io's data into IBM Db2 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 Db2.

Stacksync mirrors Deliveries / Messages, Newsletters, People, Objects from Customer.io into Databases, Schemas, Tables, Views in IBM Db2 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.
  • Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.
  • Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.

Read Customer.io with a query

Records from Customer.io are ordinary rows in IBM Db2; 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 Db2 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 IBM Db2, so triggers, jobs, and services can respond in near real time.

What you can sync between Customer.io and IBM Db2

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 Db2 objects
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Databases The connection target; each database holds the schemas a sync addresses.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Schemas Namespaces separating synced data from application and system objects.
Events Behavioral events sent via the Track API that trigger campaigns. Tables Primary read/write target for syncing rows with SaaS systems or other databases.
Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Views Read-only projections often used to expose curated slices to a sync.
Campaigns Automated workflows whose membership and metrics can be read via the App API. Indexes Support fast key lookups on sync match columns.
Broadcasts One-off sends to segments or audiences, triggerable via API. Stored Procedures Existing business logic sometimes invoked as part of write paths.

How the Customer.io and IBM Db2 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 Db2

Integration surface
SQL via JDBC/ODBC/CLI drivers; optional REST endpoints in some editions
Authentication
Database credentials, typically backed by OS or LDAP authentication
Change detection
Log-based CDC through IBM's replication tooling where licensed; otherwise polling on timestamp or audit columns
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by instance resources and workload management settings
