Why teams connect Customer.io and Okta
Keep the users, groups, and profile details that Customer.io and Okta share consistent in real time, so who can work in Customer.io always matches who your directory in Okta says belongs there.
Okta is where a company records who its people are: their accounts, the groups and roles they hold, and the attributes attached to each one. Customer.io is where a slice of those same people do their work, as agents, members, or seats, and every one of them needs a matching account with the right access. When a directory and a productivity tool are maintained by hand, someone added, moved, or offboarded in one becomes a stale entry in the other within the hour.
Stacksync syncs People, Objects, Events, Segments in Customer.io with Devices, Users, Groups, Applications in Okta bi-directionally and in real time. A user created, renamed, moved between groups, or deactivated in either system updates the matching record in the other within seconds, with field-level mapping and conflict resolution in place of CSV uploads and nightly IT batch jobs.
That matters most at the edges of employment. When both systems agree on who has an account, which groups they belong to, and whether they are still active, granting access on day one and revoking it on the last day stops being a manual checklist that trails the directory.
Common use cases
- 01 Push CRM segments and lead status into Customer.io so messaging respects sales stage.
- 02 Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
- 03 Read Application assignments and Factors into a database to report on who can reach which app and which users have strong MFA enrolled.
- 04 Drive Group Rules and policy assignments from HR attributes so access changes the moment a title, department, or location changes.
Common sync patterns
One record per person
People matched across both systems on email or an external ID stay linked, so every account and action in Customer.io ties back to the right identity in Okta.
Provision access when someone joins
A user added to Okta, or moved into a group inside it, gets the matching account or membership created in Customer.io, so a new hire can start working without a separate setup ticket.
Close access when someone leaves
When a user is disabled or removed in Okta, their account in Customer.io is deactivated in step, so offboarding shuts down access everywhere instead of leaving a live login behind.
What you can sync between Customer.io and Okta
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 | Okta objects | How this pairing syncs | |
|---|---|---|---|
| Objects Non-person entities such as accounts or companies, related to people for account-level messaging. | Users Universal Directory user records with profile attributes, credentials, and lifecycle status (staged, active, suspended, deprovisioned); full CRUD, so users are created, updated, activated, and deactivated to match an HR or identity source. | Objects is specific to Customer.io and Users to Okta — each maps to any object or custom field on the other side. | |
| Events Behavioral events sent via the Track API that trigger campaigns. | Groups Okta groups (OKTA_GROUP, APP_GROUP, BUILT_IN) and their memberships; OKTA_GROUP records and membership are written to drive app and resource access. | Events is specific to Customer.io and Groups to Okta — 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. | Applications App integrations (SAML, OIDC, SWA) with per-user and per-group assignments; read and updated to manage which identities can reach each downstream app. | Segments is specific to Customer.io and Applications to Okta — each maps to any object or custom field on the other side. | |
| Campaigns Automated workflows whose membership and metrics can be read via the App API. | Group Rules Dynamic rules that add users to groups from profile attributes; read and written to automate access based on department, title, or location. | Campaigns is specific to Customer.io and Group Rules to Okta — each maps to any object or custom field on the other side. | |
| Broadcasts One-off sends to segments or audiences, triggerable via API. | Factors (Authenticators) MFA enrollments per user (Okta Verify, WebAuthn, SMS, email); read for security-posture reporting and reset when a device is lost or rotated. | Broadcasts is specific to Customer.io and Factors (Authenticators) to Okta — each maps to any object or custom field on the other side. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Policies Sign-on, password, and authenticator-enrollment policies with their rules; read to audit access controls or updated to manage them centrally. | Deliveries / Messages is specific to Customer.io and Policies to Okta — each maps to any object or custom field on the other side. |
How changes propagate between Customer.io and Okta
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 Okta 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 Okta through its API, with automatic retries and rate-limit backoff.
Okta Customer.io Sub-second propagation
DetectionOkta notifies Stacksync of record changes through webhook events. Event Hooks send an HTTPS POST to a subscribed endpoint on events such as user.lifecycle.create and group.user_membership.add (after a one-time.
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.
- Okta: Rate limits are enforced per org, per endpoint group, per minute and vary by Okta edition; responses carry X-Rate-Limit-Limit, X-Rate-Limit-Remaining, and X-Rate-Limit-Reset headers and exceeding one returns HTTP 429. The System Log is more tightly limited (about 120 requests/minute) and a separate concurrent-request cap (default 75 in-flight transactions) also applies.

How the Customer.io and Okta 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
Okta
- Integration surface
- REST API (Okta Management API, /api/v1) with Event Hooks for outbound events and the System Log API as the change feed
- Authentication
- SSWS API tokens (Authorization: SSWS {token}) scoped to the creating admin's permissions, or OAuth 2.0 for Okta service apps using a private-key-JWT client-credentials grant with granular scopes (DPoP supported)
- Change detection
- Event Hooks send an HTTPS POST to a subscribed endpoint on events such as user.lifecycle.create and group.user_membership.add (after a one-time verification handshake); the System Log API (/api/v1/logs) is polled by the since parameter and the next Link header for a near-real-time change feed

Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Customer.io side: People, Objects, Events, Segments, plus custom fields where Customer.io exposes them. On the Okta side: Devices, Users, Groups, Applications. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Customer.io and Okta: One record per person; Provision access when someone joins; Close access when someone leaves. People matched across both systems on email or an external ID stay linked, so every account and action in Customer.io ties back to the right identity in Okta.
