Why teams connect Google Cloud SQL and Klaviyo

Mirror Klaviyo's data into Google Cloud SQL 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 Google Cloud SQL.

Stacksync mirrors Tags, Profiles, Lists, Segments from Klaviyo into Tables, Rows, Views, Transaction logs in Google Cloud SQL 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
  • Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.
  • Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.

React to changes as they happen

Updates in Klaviyo arrive as row changes in Google Cloud SQL, 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.

Read Klaviyo with a query

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

What you can sync between Google Cloud SQL 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.

Google Cloud SQL objects Klaviyo objects
Rows Read and written by primary key during each sync cycle. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
Views Read-only sources for shaping data before syncing it out. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes.
Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to. Lists Static audience memberships sync in from CRMs and forms for targeting.
Databases Scope the tables included in a sync configuration. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
Schemas Namespace tables in PostgreSQL and SQL Server instances. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.
