Why teams connect InterSystems IRIS and Klaviyo

Mirror Klaviyo's data into InterSystems IRIS 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 Klaviyo 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 InterSystems IRIS.

Stacksync mirrors Lists, Segments, Events, Metrics from Klaviyo into Tables, Views, Schemas, Persistent Classes in InterSystems IRIS 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 Klaviyo, so the tool and the database never disagree.

Common use cases

  • Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Keep reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools
  • Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing

Read Klaviyo with a query

Records from Klaviyo are ordinary rows in InterSystems IRIS; join them, index them, and use them in application logic without touching the vendor API.

Automate Klaviyo from your codebase

Write to the synced tables in InterSystems IRIS and Stacksync propagates the change into Klaviyo, replacing custom integration code.

React to changes as they happen

Updates in Klaviyo arrive as row changes in InterSystems IRIS, so triggers, jobs, and services can respond in near real time.

What you can sync between InterSystems IRIS and Klaviyo

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.

InterSystems IRIS objects Klaviyo objects
Namespaces Namespaces partition databases and determine the connection context for integrations. Metrics Event type definitions organize the activity stream used in segmentation and attribution.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Campaigns Email and SMS sends expose performance data for warehouse-based reporting.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Flows Automation definitions and their engagement data sync outward for attribution.
Views SQL views expose curated slices of data for outbound replication. Templates Message templates are accessible via API for content management workflows.
Schemas Schema organization scopes which tables a sync connection can see. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
