Why teams connect AWS Aurora PostgreSQL and Klaviyo

Mirror Klaviyo's data into AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL.

Stacksync mirrors Metrics, Campaigns, Flows, Templates from Klaviyo into Foreign keys, Replication slots and publications, Databases and schemas, Tables in AWS Aurora PostgreSQL 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

  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Capture row-level changes with logical replication and propagate them to SaaS tools without batch jobs.
  • Sync JSONB-heavy application data into structured objects in downstream business systems.

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 Klaviyo with a query

Records from Klaviyo are ordinary rows in AWS Aurora PostgreSQL; 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 AWS Aurora PostgreSQL and Stacksync propagates the change into Klaviyo, replacing custom integration code.

What you can sync between AWS Aurora PostgreSQL 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.

AWS Aurora PostgreSQL objects Klaviyo objects
Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Metrics Event type definitions organize the activity stream used in segmentation and attribution.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Campaigns Email and SMS sends expose performance data for warehouse-based reporting.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Flows Automation definitions and their engagement data sync outward for attribution.
Replication slots and publications The logical replication objects that power log-based CDC. Templates Message templates are accessible via API for content management workflows.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
