Why teams connect Klaviyo and Neo4j

Mirror Klaviyo's data into Neo4j 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 Neo4j.

Stacksync mirrors Lists, Segments, Events, Metrics from Klaviyo into Databases, Users & Roles, Nodes, Relationships in Neo4j 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
  • Mirror CRM accounts and contacts into a graph to model buying-group and referral relationships.
  • Sync product catalog and order history into Neo4j to power recommendation queries.

Automate Klaviyo from your codebase

Write to the synced tables in Neo4j 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 Neo4j, 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 Klaviyo and Neo4j

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.

Klaviyo objects Neo4j objects
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Labels Node type markers used to map source tables or objects onto the graph.
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast.
Metrics Event type definitions organize the activity stream used in segmentation and attribution. Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Users & Roles Security principals controlling what an integration credential can query or modify.
Flows Automation definitions and their engagement data sync outward for attribution. Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes.
Templates Message templates are accessible via API for content management workflows. Relationships Typed, directed edges that carry the connections syncs exist to model.
