Why teams connect Autopilot and Klaviyo

Feed Klaviyo's records into Autopilot for indexing, classification, and generation, then land the model's output back on those same records, in real time and in both directions.

Autopilot works on data it does not own. The records, conversations, tickets, messages, and events it needs to embed, classify, summarize, or answer questions about actually live in Klaviyo, the tool the team uses every day. So the value of Autopilot depends on two flows that most teams stitch together with a custom script or a one-time export: getting Klaviyo's data in, and getting the model's results back out to where people can act on them. When either flow runs on a batch or a stale snapshot, the model reasons over yesterday's data and its output never reaches the record it belongs to.

Stacksync syncs Metrics, Campaigns, Flows, Templates from Klaviyo into Autopilot continuously, so the model always works from current records instead of a snapshot, and writes Custom Fields, Smart Segments, Journeys (Triggers), Activities, the scores, labels, summaries, drafts, and embedding metadata Autopilot produces, back onto the matching record in Klaviyo. The sync is field-level and keyed on a stable identifier, so every output attaches to the exact record it came from and each system keeps its own extra fields untouched.

You decide the direction and the trigger conditions per field: pull records one way to build and keep a retrieval corpus current, push results the other way onto the operational record, or both.

Common use cases

  • 01 Add contacts to a Journey from a database event or CRM stage change to start automated onboarding or nurture sequences.
  • 02 Mirror List and Smart Segment membership into a warehouse to power attribution and audience analytics alongside other sources.
  • 03 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 04 Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data

Common sync patterns

Where Autopilot classifies or scores: results land on the record

Categories, sentiment, priority, or scores produced by Autopilot write back onto the matching record in Klaviyo, so the team acts on them in the tool they already use.

Where Autopilot generates text: drafts and summaries where the work happens

Summaries, suggested replies, or generated content from Autopilot sync onto the Klaviyo record as a field or note, ready for a person to review before it goes out.

Every output routes back to the right record

Because each item is matched on a stable identifier, an Autopilot result always attaches to the record in Klaviyo it was computed from, with no manual reconciliation.

What you can sync between Autopilot 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.

Autopilot objects Klaviyo objects How this pairing syncs
Lists Static contact lists; membership is readable per list and writable by adding or removing contacts. Lists Static audience memberships sync in from CRMs and forms for targeting. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Journeys (Triggers) Automation journeys; a contact can be added to a journey via its trigger endpoint to start automated email or SMS sequences. Metrics Event type definitions organize the activity stream used in segmentation and attribution. Journeys (Triggers) is specific to Autopilot and Metrics to Klaviyo — each maps to any object or custom field on the other side.
Activities Per-contact activity and event history (opens, clicks, journey steps); read-only feed used for engagement reporting. Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Activities is specific to Autopilot and Campaigns to Klaviyo — each maps to any object or custom field on the other side.
Contacts Core people records (email, name, custom fields, list and segment membership); upserted two-way as the primary sync object. Flows Automation definitions and their engagement data sync outward for attribution. Contacts is specific to Autopilot and Flows to Klaviyo — each maps to any object or custom field on the other side.
Custom Fields User-defined contact properties (string, number, date, boolean); discovered so field keys map cleanly to destination columns. Templates Message templates are accessible via API for content management workflows. Custom Fields is specific to Autopilot and Templates to Klaviyo — each maps to any object or custom field on the other side.
Smart Segments Rule-based dynamic audiences; membership is computed by Autopilot, so it is read-only over the API. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Smart Segments is specific to Autopilot and Catalog Items to Klaviyo — each maps to any object or custom field on the other side.

How changes propagate between Autopilot and Klaviyo

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.

Autopilot Klaviyo Interval-based propagation

DetectionStacksync polls Autopilot for changes on an incremental schedule, reading only records changed since the previous pass. No CDC.

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

Klaviyo Autopilot Sub-second propagation

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

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

Rate-limit considerations

  • Autopilot: The REST API is capped at 100 requests/minute per account; exceeding it returns HTTP 429. Enterprise plans can request a higher limit. Contact writes accept an array for bulk upsert, and list and segment reads paginate via a bookmark cursor.
  • Klaviyo: Per-endpoint burst and steady rate limits apply.

How the Autopilot and Klaviyo connectors work

Autopilot

Integration surface
REST API (Autopilot v1); Autopilot rebranded to Ortto in 2021 and the newer Ortto API co-exists with the legacy Autopilot endpoints
Authentication
Per-account API key sent in the autopilotapikey request header (generated in account settings); requests use Content-Type application/json against https://api2.autopilothq.com/v1/
Change detection
No CDC; incremental sync polls the /contacts endpoint with bookmark cursor pagination and updated timestamps. Journey webhook actions can push specific contact events, but there is no general change-subscription webhook, so polling is the reliable path.
