Why teams connect Active Directory and Customer.io
Keep the users, groups, and profile details that Customer.io and Active Directory share consistent in real time, so who can work in Customer.io always matches who your directory in Active Directory says belongs there.
Active Directory 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 Newsletters, People, Objects, Events in Customer.io with Directory roles, Service principals & applications, Organizational units, Organizational contacts in Active Directory 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 Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
- 02 Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
- 03 Read Users, Groups, and directoryRole assignments into a warehouse for periodic access reviews and SOC 2 audit evidence.
- 04 Keep security-group memberships aligned with application entitlement tables so access reflects the right teams as they change.
Common sync patterns
Provision access when someone joins
A user added to Active Directory, 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 Active Directory, their account in Customer.io is deactivated in step, so offboarding shuts down access everywhere instead of leaving a live login behind.
Keep profile attributes current
A person's name, email, department, manager, or phone number corrected in either system updates the other, so the productivity tool shows the same details the directory holds of record.
What you can sync between Active Directory and Customer.io
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.
| Active Directory objects | Customer.io objects | How this pairing syncs | |
|---|---|---|---|
| Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. | Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. | Organizational contacts is specific to Active Directory and Segments to Customer.io — each maps to any object or custom field on the other side. | |
| Users User accounts in Entra ID and on-prem AD DS; synced two-way to create, update attributes, and enable or disable accounts. | Campaigns Automated workflows whose membership and metrics can be read via the App API. | Users is specific to Active Directory and Campaigns to Customer.io — each maps to any object or custom field on the other side. | |
| Groups Security and Microsoft 365 groups; synced two-way including name, type, and owner, with membership tracked separately. | Broadcasts One-off sends to segments or audiences, triggerable via API. | Groups is specific to Active Directory and Broadcasts to Customer.io — each maps to any object or custom field on the other side. | |
| Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. | Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Group memberships is specific to Active Directory and Deliveries / Messages to Customer.io — each maps to any object or custom field on the other side. | |
| Devices Registered and joined device objects; typically read into a database for inventory and compliance reporting. | Newsletters Recurring email sends with performance metrics available for reporting syncs. | Devices is specific to Active Directory and Newsletters to Customer.io — each maps to any object or custom field on the other side. | |
| Directory roles Admin role assignments (directoryRole); read for access reviews and least-privilege governance. | People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. | Directory roles is specific to Active Directory and People to Customer.io — each maps to any object or custom field on the other side. |
How changes propagate between Active Directory and Customer.io
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.
Active Directory Customer.io Sub-second propagation
DetectionActive Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers.
DeliveryEach detected change is written to Customer.io through its API, with automatic retries and rate-limit backoff.
Customer.io Active Directory 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 Active Directory through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Active Directory: Graph throttles by resource-unit cost per app per tenant in 10-second windows (about 3,500–8,000 units by tenant size); directory delta tokens expire after ~7 days.
- Customer.io: Subject to per-API rate limits documented by Customer.io.

How the Active Directory and Customer.io connectors work
Active Directory
- Integration surface
- Microsoft Graph REST API (Entra ID / cloud) and LDAP/LDAPS (on-premises AD DS)
- Authentication
- OAuth 2.0 via the Microsoft identity platform — an app registration with application or delegated permissions (e.g. User.ReadWrite.All, Group.ReadWrite.All) and admin consent; on-prem AD DS uses a bound service account over LDAPS.
- Change detection
- Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling.

FAQ
Active Directory and Customer.io integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Active Directory and Customer.io: authenticate both systems, choose the objects to sync (such as Active Directory's Organizational contacts and Users), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Active Directory and Customer.io connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Active Directory–Customer.io integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Active Directory and Customer.io. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Active Directory: Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling. On Customer.io: Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection. 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: Newsletters, People, Objects, Events, plus custom fields where Customer.io exposes them. On the Active Directory side: Directory roles, Service principals & applications, Organizational units, Organizational contacts. 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.
