Why teams connect Active Directory and Apollo.io

Keep the people Apollo.io and Active Directory both track in agreement in real time: the internal users who own records in Apollo.io, and the customer login accounts in Active Directory.

A CRM and an identity system usually describe different populations. Apollo.io tracks customers, contacts, and the deals in motion; Active Directory governs who is allowed to sign in and what they can reach. Where the two meet is people. The reps who own records in Apollo.io are the same employees Active Directory provisions and disables, and when Active Directory also runs the login accounts for your product, the customers in Apollo.io are the same users Active Directory authenticates. Left unconnected, a departure in Active Directory leaves stale ownership sitting in Apollo.io, and a signup in Active Directory never reaches the account it belongs to.

Stacksync syncs Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with Devices, Directory roles, Service principals & applications, Organizational units in Active Directory in real time and in both directions, matching on email or an external ID and mapping field by field. You decide which system owns which fields, and new users, role and group changes, deactivations, and account status move within seconds instead of waiting on a quarterly access review or a manual export.

Common use cases

  • 01 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 03 Read Devices and service principals into a database for identity, asset, and license inventory across the tenant.
  • 04 Two-way sync Users and Groups between Microsoft Entra ID and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision automatically.

Common sync patterns

Group and entitlement membership as CRM fields

Membership of a directory group or an entitlement in Active Directory maps to fields in Apollo.io, such as product tier, plan, or internal team, so segmentation reflects real access rather than a manual guess.

Where a closed deal should provision access: Apollo.io drives Active Directory

A won or activated customer in Apollo.io can create or update the corresponding user or account in Active Directory, so provisioning starts from the CRM record instead of a separate ticket.

Where Active Directory governs your workforce: CRM users kept current

New employees in Active Directory become active users in Apollo.io with the right role, and group or department changes update their access and team, so the CRM's user list matches the directory without an admin re-keying it.

What you can sync between Active Directory and Apollo.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 Apollo.io objects How this pairing syncs
Organizational units On-prem AD DS containers (LDAP organizationalUnit) used to scope which users and groups a sync includes. Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Organizational units is specific to Active Directory and Tasks and calls to Apollo.io — each maps to any object or custom field on the other side.
Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Organizational contacts is specific to Active Directory and Custom fields to Apollo.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. Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Users is specific to Active Directory and Contacts to Apollo.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. Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Groups is specific to Active Directory and Accounts to Apollo.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. People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Group memberships is specific to Active Directory and People (database records) to Apollo.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. Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Devices is specific to Active Directory and Sequences to Apollo.io — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Apollo.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 Apollo.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 Apollo.io through its API, with automatic retries and rate-limit backoff.

Apollo.io Active Directory Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

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.
  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.

How the Active Directory and Apollo.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.
