Why teams connect Active Directory and Resend

Keep the users, groups, and profile details that Resend and Active Directory share consistent in real time, so who can work in Resend 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. Resend 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 Emails, Contacts, Audiences, Broadcasts in Resend with Organizational units, Organizational contacts, Users, Groups 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 Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • 02 Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
  • 03 Two-way sync Users and Groups between Microsoft Entra ID and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision automatically.
  • 04 Read Users, Groups, and directoryRole assignments into a warehouse for periodic access reviews and SOC 2 audit evidence.

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 Resend ties back to the right identity in Active Directory.

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 Resend, 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 Resend is deactivated in step, so offboarding shuts down access everywhere instead of leaving a live login behind.

What you can sync between Active Directory and Resend

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 Resend objects How this pairing syncs
Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. Emails Sent messages retrievable by ID with current delivery status. Organizational contacts is specific to Active Directory and Emails to Resend — 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 Recipient records with email, name, and subscription state, synced from CRMs or databases. Users is specific to Active Directory and Contacts to Resend — 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. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Groups is specific to Active Directory and Audiences to Resend — 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. Broadcasts One-to-many campaign sends addressed to an audience. Group memberships is specific to Active Directory and Broadcasts to Resend — 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. Domains Verified sending domains with DNS and DKIM status. Devices is specific to Active Directory and Domains to Resend — 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. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Directory roles is specific to Active Directory and Email events to Resend — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Resend

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 Resend 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 Resend through its API, with automatic retries and rate-limit backoff.

Resend Active Directory Sub-second propagation

DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle 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.

How the Active Directory and Resend 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.
