Why teams connect Greenhouse and Zendesk

Keep the people, teams, and status that Zendesk and Greenhouse share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in Zendesk 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. Greenhouse 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 Tickets Comments, Users, Organizations, Attachments in Zendesk with Departments and Offices, Candidates, Applications, Jobs in Greenhouse bi-directionally and in real time. A person added, moved, or offboarded in Greenhouse creates or updates the matching user in Zendesk within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Zendesk captures details of its own, such as a corrected contact or a login identity, those can flow back to Greenhouse 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 tickets, users, and organizations into Postgres so support analytics run on SQL instead of repeated API pulls.
  • 02 Write CRM account tier, owner, and renewal data onto Zendesk organizations and ticket fields so agents see context in the ticket.
  • 03 Stream Jobs, Departments, and Offices into a reporting database for recruiting funnel and time-to-fill dashboards.
  • 04 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.

Common sync patterns

Onboarding: access ready on day one

A new hire recorded in Greenhouse creates the matching user in Zendesk 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 Greenhouse, the matching account in Zendesk is deactivated or flagged, so departures do not leave open access behind.

One employee directory

A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.

What you can sync between Greenhouse and Zendesk

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.

Greenhouse objects Zendesk objects How this pairing syncs
Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Users End users and agents; matched to CRM contacts to keep requester data consistent. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. Attachments Synced with incremental and full sync per the Stacksync docs. Departments and Offices is specific to Greenhouse and Attachments to Zendesk — each maps to any object or custom field on the other side.
Candidates Person records with contact details, tags, and custom fields; read and written via Harvest, often created from sourcing or enrichment pipelines. Ticket Forms Synced with incremental and full sync per the Stacksync docs. Candidates is specific to Greenhouse and Ticket Forms to Zendesk — each maps to any object or custom field on the other side.
Applications Links a Candidate to a Job; carries current stage, status, and source. Movable, rejectable, and hireable through Harvest write calls. Tickets The central work object; synced to databases for SLA and volume reporting or mirrored into engineering tools. Applications is specific to Greenhouse and Tickets to Zendesk — each maps to any object or custom field on the other side.
Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. Tickets Comments Synced with incremental and full sync per the Stacksync docs. Jobs is specific to Greenhouse and Tickets Comments to Zendesk — each maps to any object or custom field on the other side.
Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. Organizations Company groupings for users; typically kept aligned with CRM accounts. Offers is specific to Greenhouse and Organizations to Zendesk — each maps to any object or custom field on the other side.

How changes propagate between Greenhouse and Zendesk

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.

Greenhouse Zendesk Sub-second propagation

DetectionGreenhouse notifies Stacksync of record changes through webhook events. HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after /.

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

Zendesk Greenhouse Sub-second propagation

DetectionZendesk notifies Stacksync of record changes through webhook events. Incremental export endpoints with cursor-based pagination, plus webhooks fired by triggers.

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

Rate-limit considerations

  • Greenhouse: Harvest enforces a per-integration limit over a rolling 10-second window (X-RateLimit-Limit, commonly 50 requests / 10s for approved integrations); responses carry X-RateLimit-Remaining and, on a 429, X-RateLimit-Reset and Retry-After.
  • Zendesk: Request limits vary by plan; incremental export endpoints have their own allowances.
