Why teams connect Klaviyo and Newrelic

Connect the tickets, records, and events in Klaviyo to the systems engineering runs in Newrelic, kept current in real time and in both directions.

Klaviyo is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Newrelic 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 Metrics, Campaigns, Flows, Templates in Klaviyo with Synthetics Monitors, Custom Events, Change Tracking (Deployments), Dashboards in Newrelic 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.

Common use cases

  • 01 Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • 02 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 03 Sync the Entity catalog into a CMDB or warehouse for asset inventory, and add or replace entity Tags to keep ownership and environment metadata current.
  • 04 Provision Synthetics Monitors from a service catalog and read their results via NRQL for availability and latency reporting in SQL.

Common sync patterns

One shared record across both systems

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.

Where Newrelic tracks engineering work: requests become issues

A ticket or request raised in Klaviyo opens or updates a matching issue in Newrelic, and status, comments, and resolution flow back, so support and engineering work the same item instead of retyping it.

Where Newrelic moves messages between services: activity lands on the stream

Records created or changed in Klaviyo publish to the queue or topic in Newrelic as they happen, so downstream services react to real events rather than polling for them.

What you can sync between Klaviyo and Newrelic

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 Newrelic objects How this pairing syncs
Templates Message templates are accessible via API for content management workflows. Entities The entity catalog of APM applications, hosts, services, and monitors searched via NerdGraph entitySearch; read for inventory, with tags added or replaced through taggingAddTagsToEntity so ownership and environment metadata stay in sync. Templates is specific to Klaviyo and Entities to Newrelic — each maps to any object or custom field on the other side.
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Workloads Workload groupings of related entities via NerdGraph workloadCreate/workloadUpdate/workloadDelete with full CRUD; read for status rollups or provisioned from a service catalog to keep team-level views current. Catalog Items is specific to Klaviyo and Workloads to Newrelic — each maps to any object or custom field on the other side.
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Synthetics Monitors Synthetic uptime and scripted browser checks managed through NerdGraph synthetics mutations (create, update, delete); monitor results are read via NRQL for availability and latency reporting. Tags is specific to Klaviyo and Synthetics Monitors to Newrelic — each maps to any object or custom field on the other side.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Custom Events Custom events posted write-only to the Event API on insights-collector with a License/Ingest key; business or pipeline events pushed into New Relic to enrich dashboards, then queried back out with NRQL. Profiles is specific to Klaviyo and Custom Events to Newrelic — each maps to any object or custom field on the other side.
Lists Static audience memberships sync in from CRMs and forms for targeting. Change Tracking (Deployments) Deployment and change markers recorded through NerdGraph changeTrackingCreateDeployment; written from CI/CD to annotate charts, and read back via NRQL on the Deployment event for release correlation. Lists is specific to Klaviyo and Change Tracking (Deployments) to Newrelic — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Dashboards Dashboard definitions and widgets via NerdGraph dashboardCreate/dashboardUpdate/dashboardDelete mutations and entity queries, with full CRUD; exported for backup and audit or provisioned and updated programmatically from a source of truth. Segments is specific to Klaviyo and Dashboards to Newrelic — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and Newrelic

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.

Klaviyo Newrelic Sub-second propagation

DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.

DeliveryEach detected change is written to Newrelic through its API, with automatic retries and rate-limit backoff.

Newrelic Klaviyo Sub-second propagation

DetectionNewrelic notifies Stacksync of record changes through webhook events. NRQL polling over timestamp windows for telemetry (events, metrics, logs, spans).

DeliveryEach detected change is written to Klaviyo through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • Newrelic: NerdGraph allows 25 concurrent requests per user and returns HTTP 429 when exceeded; NRQL run via APIs is capped at 3,000 queries per account per minute with a 5-second default timeout and about 5,000 data points per response. The Event API accepts 1MB per POST and 100,000 POSTs per minute per account.

How the Klaviyo and Newrelic connectors work

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

Rate limits
Per-endpoint burst and steady rate limits apply

Newrelic

Integration surface
NerdGraph (GraphQL) plus REST data-ingest APIs (Event, Metric, Log, Trace) and the legacy REST API v2
Authentication
User API key (prefixed NRAK-) sent in the API-Key header for NerdGraph queries and mutations; the data-ingest APIs (Event, Metric, Log) use a License/Ingest key in the Api-Key header. Keys, endpoints, and data are region-scoped (US, EU, JP).
Change detection
NRQL polling over timestamp windows for telemetry (events, metrics, logs, spans); config objects such as dashboards, alert policies, and workloads carry no modified-date and are diffed on each run. Alert workflows can push outbound webhook notifications for near-real-time alerting. No CDC feed.
