Two-way sync
Changes in Datadog or Klaviyo instantly reflect in both systems. No stale data, no manual imports.
Keep Datadog 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.
Klaviyo is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Datadog is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.
Stacksync syncs Events, Metrics, Campaigns, Flows in Klaviyo with Monitors, Logs, Events, Dashboards in Datadog field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.
Open items, throughput, and error counts from Klaviyo replicate into Datadog, so the operational view reflects what is actually happening in the business.
Where both systems keep records for the same contacts, items, or users, a correction in either updates the other, ending dual maintenance and keeping IDs aligned for every other flow.
A ticket or request raised in Klaviyo opens or updates a matching issue in Datadog, and status, comments, and resolution flow back, so support and engineering work the same item instead of retyping it.
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.
| Datadog objects | Klaviyo objects | How this pairing syncs | |
|---|---|---|---|
| Events The event stream (deploys, alerts, comments) searched via the v2 Events endpoint and posted via POST /api/v1/events; used to correlate deploy and incident timelines or to publish deploy and pipeline events into Datadog. | Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Metrics Time-series metrics queried in aggregate windows through the query API and submitted via POST /api/v1/series; individual raw points cannot be extracted beyond retention. | Metrics Event type definitions organize the activity stream used in segmentation and attribution. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Service Level Objectives SLO definitions and status history via the v1 SLO API with full CRUD; read out for reliability and error-budget reporting, or provisioned and updated from a reliability config. | Templates Message templates are accessible via API for content management workflows. | Service Level Objectives is specific to Datadog and Templates to Klaviyo — each maps to any object or custom field on the other side. | |
| Hosts Infrastructure host inventory with tags and metadata from the v1 host list API; loaded into a CMDB or warehouse for asset tracking, and hosts can be muted or unmuted via the API. | Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. | Hosts is specific to Datadog and Catalog Items to Klaviyo — each maps to any object or custom field on the other side. | |
| Monitors Alert definitions with query, thresholds, and current state via the v1 Monitors API, which supports full create, update, and delete; Stacksync reads alert state into a warehouse or provisions and updates monitors from a config source. | Tags Organizational labels on campaigns, flows, and lists support reporting rollups. | Monitors is specific to Datadog and Tags to Klaviyo — each maps to any object or custom field on the other side. | |
| Logs Log events searched via the v2 Logs search endpoint by time window and submittable through the log intake API; commonly streamed to a warehouse for retention beyond Datadog's storage period. | Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Logs is specific to Datadog and Profiles to Klaviyo — each maps to any object or custom field on the other side. |
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
DetectionDatadog notifies Stacksync of record changes through webhook events. Polling with time-windowed search queries on Logs and Events (timestamp cursor).
DeliveryEach detected change is written to Klaviyo through its API, with automatic retries and rate-limit backoff.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Datadog–Klaviyo connection.
Changes in Datadog or Klaviyo instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Datadog 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 Datadog or Klaviyo record.
Track your Datadog ⇄ Klaviyo sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Datadog 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 Datadog 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 Datadog 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 Datadog and Klaviyo: authenticate both systems, choose the objects to sync (such as Datadog's Events and Metrics), map fields visually, and changes propagate both ways in milliseconds — no code required.
Datadog: REST API (v1 and v2). Authentication: API key (DD-API-KEY) plus an Application key (DD-APPLICATION-KEY) sent as request headers; application keys are tied to the creating user and inherit that user's permissions and authorization scopes. 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. Datadog: The REST API supports full create/update/delete on Monitors, Dashboards, SLOs, and Incidents, and accepts submitted Events and Metrics, so the connector can write into Datadog as well as read from it. Stacksync's field mapping accounts for these differences between Datadog 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 Datadog and Klaviyo records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Datadog and Klaviyo connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Datadog–Klaviyo integration in-house.
Yes — Stacksync ships production-grade connectors for both Datadog and Klaviyo. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
