Why teams connect Klaviyo and RavenDB

Mirror Klaviyo's data into RavenDB 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 RavenDB.

Stacksync mirrors Lists, Segments, Events, Metrics from Klaviyo into Time series, Data subscriptions, Documents, Collections in RavenDB 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 reference data from relational systems into RavenDB collections that serve application reads.
  • Consolidate documents from distributed RavenDB clusters into one reporting store.

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 RavenDB; 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 RavenDB and Stacksync propagates the change into Klaviyo, replacing custom integration code.

What you can sync between Klaviyo and RavenDB

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 RavenDB objects
Lists Static audience memberships sync in from CRMs and forms for targeting. Data subscriptions Server-side change feeds that push matching documents to consumers
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Documents JSON records, the primary unit read and written during sync
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. Collections Groupings of documents by type, mapped to tables in relational targets
Metrics Event type definitions organize the activity stream used in segmentation and attribution. Indexes Static and auto indexes used to query documents for filtered reads
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Attachments Binary payloads stored with documents, handled separately from the JSON body
Flows Automation definitions and their engagement data sync outward for attribution. Revisions Historical versions of documents, useful for audit-oriented replication
