Why teams connect Hibob and Resend
Keep the people, teams, and status that Resend and Hibob share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.
Each tool in Resend keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Hibob is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.
Stacksync syncs Domains, Email events, API keys, Emails in Resend with Work, Salaries, Time off, Lifecycle in Hibob bi-directionally and in real time. A person added, moved, or offboarded in Hibob creates or updates the matching user in Resend within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Resend captures details of its own, such as a corrected contact or a login identity, those can flow back to Hibob in whichever direction you configure.
Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.
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 Push Salaries and Variable Pay from Bob into a payroll provider or warehouse each pay cycle, using the Payroll-permitted service user.
- 04 Mirror Work data (department, site, manager, title) into an org-chart or reporting warehouse for headcount and structure analysis.
Common sync patterns
Where Resend routes or assigns work by person: assignments follow the org
When someone changes teams or managers in Hibob, the queues, ownership, or approvals in Resend update to match, so work reaches whoever holds the role now.
Onboarding: access ready on day one
A new hire recorded in Hibob creates the matching user in Resend with the right team and manager already set, so people can start working without waiting on a provisioning ticket.
Offboarding: no standing access after a departure
When someone is marked as leaving in Hibob, the matching account in Resend is deactivated or flagged, so departures do not leave open access behind.
What you can sync between Hibob 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.
| Hibob objects | Resend objects | How this pairing syncs | |
|---|---|---|---|
| Documents Employee documents accessed under the Docs API; gated behind the Documents permission granted per service user. | Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. | Documents is specific to Hibob and Audiences to Resend — each maps to any object or custom field on the other side. | |
| Named lists Dropdown option lists such as departments and sites used to resolve field values when mapping People records during sync. | Broadcasts One-to-many campaign sends addressed to an audience. | Named lists is specific to Hibob and Broadcasts to Resend — each maps to any object or custom field on the other side. | |
| People (Employees) Core employee records with out-of-the-box and custom fields; read via POST /people/search, created and updated through the /people endpoints. | Domains Verified sending domains with DNS and DKIM status. | People (Employees) is specific to Hibob and Domains to Resend — each maps to any object or custom field on the other side. | |
| Employment Historical table of job terms, contract, and working pattern under /people/{id}/employment; full CRUD, entries keyed by effectiveDate. | Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. | Employment is specific to Hibob and Email events to Resend — each maps to any object or custom field on the other side. | |
| Work Reporting line, department, site, and title under /people/{id}/work; drives the org chart and is synced two-way to directories. | API keys Scoped credentials managed per environment for send and read access. | Work is specific to Hibob and API keys to Resend — each maps to any object or custom field on the other side. | |
| Salaries Compensation history at /people/{id}/salaries; full CRUD but gated behind the Payroll permission on the service user. | Emails Sent messages retrievable by ID with current delivery status. | Salaries is specific to Hibob and Emails to Resend — each maps to any object or custom field on the other side. |
How changes propagate between Hibob 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.
Hibob Resend Sub-second propagation
DetectionHibob notifies Stacksync of record changes through webhook events. Webhooks fire for employee created/updated/deleted, table-entry created/updated, time off, and lifecycle events.
DeliveryEach detected change is written to Resend through its API, with automatic retries and rate-limit backoff.
Resend Hibob Sub-second propagation
DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.
DeliveryEach detected change is written to Hibob through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Hibob: Rate limits are enforced per service user; violations return HTTP 429 with X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. The docs list POST /people/search at 50 requests per minute, and bulk /people/search is preferred over per-record reads.

How the Hibob and Resend connectors work
Hibob
- Integration surface
- REST API (the Bob API)
- Authentication
- Service User credentials over HTTP Basic auth (Base64-encoded serviceUserId:serviceUserToken); permissions granted per data category (People, Payroll, Documents) in Bob admin
- Change detection
- Webhooks fire for employee created/updated/deleted, table-entry created/updated, time off, and lifecycle events; the employee.updated payload flags which fields changed and Bob recommends an API call for the full record. There is no CDC stream, and deleting a table entry fires no webhook (Bob has no table-entry deletion event).

FAQ
Hibob and Resend integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Hibob and Resend: authenticate both systems, choose the objects to sync (such as Hibob's Documents and Named lists), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Hibob: Webhooks fire for employee created/updated/deleted, table-entry created/updated, time off, and lifecycle events; the employee.updated payload flags which fields changed and Bob recommends an API call for the full record. There is no CDC stream, and deleting a table entry fires no webhook (Bob has no table-entry deletion event). On Resend: Webhooks for email lifecycle events; polling for contact and audience state. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Resend side: Domains, Email events, API keys, Emails, plus custom fields where Resend exposes them. On the Hibob side: Work, Salaries, Time off, Lifecycle. 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.
