Why teams connect Azure Active Directory and Resend

Keep the users, groups, and profile details that Resend and Azure Active Directory share consistent in real time, so who can work in Resend always matches who your directory in Azure Active Directory says belongs there.

Azure 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 Broadcasts, Domains, Email events, API keys in Resend with Directory roles, Devices, Users, Groups in Azure 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 Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • 02 Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • 03 Provision and deprovision Entra ID Users and Group memberships from an HR system of record so account enablement follows employment status.
  • 04 Sync manager, department, and jobTitle from an HRIS back onto Entra ID User attributes to keep dynamic groups and Conditional Access accurate.

Common sync patterns

Close access when someone leaves

When a user is disabled or removed in Azure Active Directory, their account in Resend 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.

Mirror group and role membership

Moving a user between groups or roles in Azure Active Directory updates their team, permission set, or seat in Resend, so what someone can do reflects where they sit in the directory.

What you can sync between Azure 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.

Azure Active Directory objects Resend objects How this pairing syncs
Applications App registrations under /applications; usually read into a database or CMDB for app ownership and credential-expiry tracking. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Applications is specific to Azure Active Directory and Contacts to Resend — each maps to any object or custom field on the other side.
Service principals /servicePrincipals (enterprise apps) plus appRoleAssignments; read for app inventory and access-posture reporting. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Service principals is specific to Azure Active Directory and Audiences to Resend — each maps to any object or custom field on the other side.
Directory roles /directoryRoles and roleManagement assignments; read for privileged-access reviews, with role-assignment writes where the granted scopes permit. Broadcasts One-to-many campaign sends addressed to an audience. Directory roles is specific to Azure Active Directory and Broadcasts to Resend — each maps to any object or custom field on the other side.
Devices /devices registered or joined to the tenant; typically read-only into asset and security databases. Domains Verified sending domains with DNS and DKIM status. Devices is specific to Azure Active Directory and Domains to Resend — each maps to any object or custom field on the other side.
Users /users in Microsoft Graph; synced two-way — profile attributes, accountEnabled, and assignedLicenses are read out while provisioning writes (create, update, disable, delete) are pushed back. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Users is specific to Azure Active Directory and Email events to Resend — each maps to any object or custom field on the other side.
Groups /groups covering security and Microsoft 365 groups; created, updated, and deleted through Graph, and read into warehouses for entitlement reporting. API keys Scoped credentials managed per environment for send and read access. Groups is specific to Azure Active Directory and API keys to Resend — each maps to any object or custom field on the other side.

How changes propagate between Azure 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.

Azure Active Directory Resend Sub-second propagation

DetectionAzure Active Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (deltaLink tokens returning only changed users and groups, with @removed deletions) paired with change-notification.

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

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

Rate-limit considerations

  • Azure Active Directory: Resource-unit throttling: roughly 8,000 ResourceUnits per 10 seconds per app for reads on tenants over 500 users, writes near 3,000 requests per 2.5 minutes; 429 responses include a Retry-After header.
