Why teams connect Asana and Klaviyo

Stop re-entering the same information in Asana and Klaviyo: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Users, Portfolios, Tags, Teams / Workspaces in Asana with Profiles, Lists, Segments, Events in Klaviyo in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • 01 Mirror Projects, Sections, and Portfolios into a warehouse for cross-team reporting on status, timelines, and workload without CSV exports.
  • 02 Push support tickets or intake requests from an operational database into Asana Tasks, then read completion and status Custom fields back when work finishes.
  • 03 Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • 04 Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data

Common sync patterns

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

What you can sync between Asana 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.

Asana objects Klaviyo objects How this pairing syncs
Tags Labels applied across Tasks; synced as a many-to-many attribute for filtering and categorization. Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Teams / Workspaces Organizational containers that hold projects and members; used to scope which projects a given sync covers. Flows Automation definitions and their engagement data sync outward for attribution. Teams / Workspaces is specific to Asana and Flows to Klaviyo — each maps to any object or custom field on the other side.
Tasks The primary unit of work and main record; created, updated, completed, and deleted via REST and synced two-way. Subtasks are Tasks with a parent reference. Templates Message templates are accessible via API for content management workflows. Tasks is specific to Asana and Templates to Klaviyo — each maps to any object or custom field on the other side.
Projects Collections of Tasks with a layout (list, board, timeline, calendar); each project maps to a synced table scope and its custom fields define the mapping. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Projects is specific to Asana and Catalog Items to Klaviyo — each maps to any object or custom field on the other side.
Sections Ordered groupings of Tasks within a project; synced as a grouping attribute or category field on the row. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Sections is specific to Asana and Profiles to Klaviyo — each maps to any object or custom field on the other side.
Custom fields Typed fields (text, number, enum, multi-enum, date, people) defined at project or workspace level; mapped to database columns, with enum values written by option GID. Lists Static audience memberships sync in from CRMs and forms for targeting. Custom fields is specific to Asana and Lists to Klaviyo — each maps to any object or custom field on the other side.

How changes propagate between Asana 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.

Asana Klaviyo Sub-second propagation

DetectionAsana notifies Stacksync of record changes through webhook events. Resource-scoped webhooks (established with an X-Hook-Secret handshake) POST events on create, change, and delete.

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

Klaviyo Asana Sub-second propagation

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

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

Rate-limit considerations

  • Asana: Per token: 1,500 requests/minute on paid plans, 150/minute on free; the Search API is capped at 60/minute; concurrency caps at 50 GET and 15 write requests. Exceeding a limit returns HTTP 429 with a Retry-After header, and a separate cost-based limiter applies to complex graph traversals.
  • Klaviyo: Per-endpoint burst and steady rate limits apply.
