Two-way sync
Changes in Elasticsearch or Klaviyo instantly reflect in both systems. No stale data, no manual imports.
Keep Elasticsearch and Klaviyo in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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.
Records from Klaviyo are ordinary rows in Elasticsearch; join them, index them, and use them in application logic without touching the vendor API.
Write to the synced tables in Elasticsearch and Stacksync propagates the change into Klaviyo, replacing custom integration code.
Updates in Klaviyo arrive as row changes in Elasticsearch, so triggers, jobs, and services can respond in near real time.
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. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Elasticsearch–Klaviyo connection.
Changes in Elasticsearch or Klaviyo instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Elasticsearch or Klaviyo data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Elasticsearch or Klaviyo record.
Track your Elasticsearch ⇄ Klaviyo sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Elasticsearch and Klaviyo.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Elasticsearch and Klaviyo with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Elasticsearch and Klaviyo objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Elasticsearch and Klaviyo: authenticate both systems, choose the objects to sync (such as Elasticsearch's Aliases and Data streams), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Elasticsearch and Klaviyo: Read Klaviyo with a query; Automate Klaviyo from your codebase; React to changes as they happen. Records from Klaviyo are ordinary rows in Elasticsearch; join them, index them, and use them in application logic without touching the vendor API.
Elasticsearch: REST API (JSON over HTTP). Authentication: API keys or basic authentication; Elastic Cloud also issues service account tokens. Klaviyo: REST API compliant with the JSON:API specification. Authentication: OAuth 2.0 for apps or private API keys. Stacksync manages authentication, retries, and rate limits on both sides.
Klaviyo: Profiles accept arbitrary custom properties, and events are append-only records tied to named metrics, which together form the segmentation model external data is synced into. Elasticsearch: A field's mapping is fixed once indexed; changing a field type requires reindexing into a new index, typically swapped in behind an alias. Stacksync's field mapping accounts for these differences between Elasticsearch and Klaviyo without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Elasticsearch and Klaviyo records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Elasticsearch and Klaviyo connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Elasticsearch–Klaviyo integration in-house.
As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
Immediately get alerted about record syncing issues over email, Slack, PagerDuty and WhatsApp. Resolve issues from a centralized dashboard with retry and revert options.
