Why teams connect Amazon RDS and Klaviyo

Mirror Klaviyo's data into Amazon RDS 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 Amazon RDS.

Stacksync mirrors Templates, Catalog Items, Tags, Profiles from Klaviyo into Primary and Unique Keys, Read Replicas, Stored Procedures, Databases in Amazon RDS 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

  • Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • Use a read replica as the sync source to keep change capture load off the primary instance
  • Bi-directional sync between an RDS database and a CRM so application data and sales data stay consistent without custom integration code

React to changes as they happen

Updates in Klaviyo arrive as row changes in Amazon RDS, 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 Amazon RDS; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Amazon RDS 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.

Amazon RDS objects Klaviyo objects
Schemas Namespaces within a database used to isolate synced tables. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
Tables The core sync target; rows map to records in connected SaaS systems. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
Views Read-side projections exposed to outbound syncs. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes.
Columns Field-level mapping targets, typed per the underlying engine. Lists Static audience memberships sync in from CRMs and forms for targeting.
Primary and Unique Keys Match keys for idempotent upserts. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
Read Replicas Low-impact read endpoints often used as the source side of a sync. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.

How the Amazon RDS and Klaviyo connectors work

Amazon RDS

Integration surface
SQL wire protocol of the chosen engine (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle)
Authentication
Database credentials over SSL/TLS, or IAM database authentication on supported engines
Change detection
Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC; enabled through RDS parameter groups, with polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance class, storage IOPS, and connection limits

Klaviyo

Integration surface
REST API compliant with the JSON:API specification
Authentication
OAuth 2.0 for apps or private API keys
Change detection
Polling on updated timestamps; outbound webhooks exist for event topics (availability depends on plan or app-partner status) and as flow webhook actions
Capabilities
