Why teams connect Front and Greenhouse

Keep the people, teams, and status that Front 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 Front 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 Messages, Comments, Contacts, Accounts in Front with Users, Departments and Offices, Candidates, Applications in Greenhouse bi-directionally and in real time. A person added, moved, or offboarded in Greenhouse creates or updates the matching user in Front within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Front 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 Write CRM account tier, owner, and renewal data into Front contact and account custom fields so it shows next to the conversation.
  • 02 Keep Front contacts and accounts aligned with CRM contacts and accounts in both directions.
  • 03 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update stage, status, and custom fields in SQL while recruiters stay in Greenhouse.
  • 04 Write enriched or sourced Candidates from external tools into Greenhouse and keep contact fields refreshed as data changes.

Common sync patterns

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.

Org and team structure kept current

Department, team, and reporting-line changes from Greenhouse keep the groups, queues, or projects in Front assigned to the right people.

Where Front routes or assigns work by person: assignments follow the org

When someone changes teams or managers in Greenhouse, the queues, ownership, or approvals in Front update to match, so work reaches whoever holds the role now.

What you can sync between Front and Greenhouse

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.

Front objects Greenhouse objects How this pairing syncs
Tags Labels applied to conversations; drive routing and category-level analytics. Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. Tags is specific to Front and Jobs to Greenhouse — each maps to any object or custom field on the other side.
Teammates Agents; used for ownership mapping and workload reporting. Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. Teammates is specific to Front and Offers to Greenhouse — each maps to any object or custom field on the other side.
Channels Connected addresses (email, SMS, chat); define where messages originate and send from. Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. Channels is specific to Front and Scorecards to Greenhouse — each maps to any object or custom field on the other side.
Conversations The central threaded unit that messages, comments, and tags attach to; synced for support analytics. Scheduled Interviews Interview events with interviewers, times, and rooms; full create/update/delete support for calendar and reporting syncs. Conversations is specific to Front and Scheduled Interviews to Greenhouse — each maps to any object or custom field on the other side.
Messages Inbound and outbound emails, chats, and SMS within a conversation; read out for response-time reporting. Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Messages is specific to Front and Users to Greenhouse — each maps to any object or custom field on the other side.
Comments Internal team notes on conversations; usually read-only in syncs. Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. Comments is specific to Front and Departments and Offices to Greenhouse — each maps to any object or custom field on the other side.

How changes propagate between Front and Greenhouse

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.

Front Greenhouse Sub-second propagation

DetectionFront notifies Stacksync of record changes through webhook events. Application webhooks and rule-triggered webhooks, with the events endpoint available for polling.

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

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

Rate-limit considerations

  • Front: Request limits vary by plan.
  • 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.
