Why teams connect Customer.io and Wrike

Stop re-entering the same information in Customer.io and Wrike: 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 Segments, Campaigns, Broadcasts, Deliveries / Messages in Customer.io with Folders & Projects, Custom Fields, Comments, Timelogs in Wrike 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 Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • 02 Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
  • 03 Sync Comments and status changes from Wrike into a database so downstream dashboards and tools react to project progress in near real time.
  • 04 Two-way sync of Tasks and their Custom Fields between a Wrike project and Postgres so ops teams work in SQL while project owners stay in Wrike.

Common sync patterns

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.

Where Wrike is where the team documents or plans: keep its data fed

Information that originates in Customer.io stays current in Wrike instead of going stale after a one-time paste.

What you can sync between Customer.io and Wrike

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.

Customer.io objects Wrike objects How this pairing syncs
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Comments Discussion and activity entries attached to Tasks and Folders; read out for history and reporting or written back as comments. Deliveries / Messages is specific to Customer.io and Comments to Wrike — each maps to any object or custom field on the other side.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Timelogs Time-tracking entries logged against Tasks; read for billing and utilization reporting or written back when hours are recorded elsewhere. Newsletters is specific to Customer.io and Timelogs to Wrike — each maps to any object or custom field on the other side.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Contacts Account members and user groups referenced by task responsibles and authors; read to resolve IDs to names and email addresses. People is specific to Customer.io and Contacts to Wrike — each maps to any object or custom field on the other side.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Workflows Sets of custom statuses grouped into stages (Active, Completed, Cancelled, Deferred); read to map task status transitions to database values. Objects is specific to Customer.io and Workflows to Wrike — each maps to any object or custom field on the other side.
Events Behavioral events sent via the Track API that trigger campaigns. Spaces Top-level containers that hold Folders, Projects, and their members; used to scope which Folders a given sync covers. Events is specific to Customer.io and Spaces to Wrike — each maps to any object or custom field on the other side.
Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Tasks The primary unit of work and main record; created, updated, completed, and deleted via the REST v4 API and synced two-way. Subtasks are Tasks linked by superTask/subTask references. Segments is specific to Customer.io and Tasks to Wrike — each maps to any object or custom field on the other side.

How changes propagate between Customer.io and Wrike

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.

Customer.io Wrike Sub-second propagation

DetectionCustomer.io notifies Stacksync of record changes through webhook events. Reporting webhooks push message and delivery events.

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

Wrike Customer.io Sub-second propagation

DetectionWrike notifies Stacksync of record changes through webhook events. Webhooks scoped to a folder, a space, or the whole account fire on events like TaskCreated, TaskStatusChanged, and FolderCreated, with event.

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

Rate-limit considerations

  • Customer.io: Subject to per-API rate limits documented by Customer.io.
  • Wrike: Approximately 400 requests/minute per user (estimated on a per-second basis) with a higher per-IP ceiling; exceeding the limit or tripping Wrike's internal overload protection returns HTTP 429, handled with exponential backoff.

How the Customer.io and Wrike connectors work

Customer.io

Integration surface
REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
Authentication
Basic auth with site ID and API key for the Track API; bearer token for the App API
Change detection
Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
Capabilities
read · write · webhooks
Rate limits
Subject to per-API rate limits documented by Customer.io

Wrike

Integration surface
REST API v4 (JSON), single account endpoint such as www.wrike.com/api/v4; the data-center host (US or EU) comes from the OAuth token response, plus REST-managed Webhooks
Authentication
OAuth 2.0 for multi-user apps (Authorization header carrying access_token and requested scopes), and a legacy Permanent Access Token for single-account and testing use
Change detection
Webhooks scoped to a folder, a space, or the whole account fire on events like TaskCreated, TaskStatusChanged, and FolderCreated, with event filtering and custom payload fields; polling the task updatedDate is the fallback
Capabilities
read · write · webhooks
Rate limits
Approximately 400 requests/minute per user (estimated on a per-second basis) with a higher per-IP ceiling; exceeding the limit or tripping Wrike's internal overload protection returns HTTP 429, handled with exponential backoff
