Why teams connect Elasticsearch and Klaviyo

Mirror Klaviyo's data into Elasticsearch 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 Elasticsearch.

Stacksync mirrors Metrics, Campaigns, Flows, Templates from Klaviyo into Index templates, Indices, Documents, Index mappings in Elasticsearch 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
  • Feed enriched customer records into an index used for vector or hybrid search in AI applications.
  • Sync CRM accounts and contacts into an Elasticsearch index to power internal search across customer records.

Read Klaviyo with a query

Records from Klaviyo are ordinary rows in Elasticsearch; 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 Elasticsearch 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 Elasticsearch, so triggers, jobs, and services can respond in near real time.

What you can sync between Elasticsearch 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.

Elasticsearch objects Klaviyo objects
Aliases Stable read/write names that let a sync cut over between index versions without downtime. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
Data streams Append-only targets for time-series or event data pushed from source systems. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
Ingest pipelines Server-side transforms applied to documents as a sync writes them. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes.
Index templates Reusable settings and mappings applied automatically to new indices a sync creates. Lists Static audience memberships sync in from CRMs and forms for targeting.
Indices Target containers for synced records; each holds a table-like collection of JSON documents. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
Documents The unit of sync; JSON records created, updated, and deleted by _id. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.

How the Elasticsearch and Klaviyo connectors work

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities
read · write
Rate limits
No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity

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
read · write · webhooks
Rate limits
Per-endpoint burst and steady rate limits apply
