Why teams connect Azure SQL Database and Klaviyo

Mirror Klaviyo's data into Azure SQL Database 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 Azure SQL Database.

Stacksync mirrors Tags, Profiles, Lists, Segments from Klaviyo into Tables, Views, Schemas, Rows and columns in Azure SQL Database 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 catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • Expose SaaS data (billing, support tickets) as tables in Azure SQL for reporting teams already on Microsoft tooling.
  • Replicate Azure SQL tables to a warehouse without building custom CDC pipelines.

Automate Klaviyo from your codebase

Write to the synced tables in Azure SQL Database 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 Azure SQL Database, so triggers, jobs, and services can respond in near real time.

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.

What you can sync between Azure SQL Database 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.

Azure SQL Database objects Klaviyo objects
Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts. Metrics Event type definitions organize the activity stream used in segmentation and attribution.
Change tracking / CDC tables System-maintained change records used to drive incremental sync. Campaigns Email and SMS sends expose performance data for warehouse-based reporting.
Tables The primary sync target; rows map one-to-one to records in the paired system. Flows Automation definitions and their engagement data sync outward for attribution.
Views Read-only projections used when the sync should expose a curated shape rather than raw tables. Templates Message templates are accessible via API for content management workflows.
Schemas Namespaces that organize tables and control which objects a sync user can reach. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
Rows and columns Standard relational records with typed columns; primary keys anchor upserts. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
