Why teams connect Greenhouse and Intercom

Keep the people who own accounts in Intercom in step with the workforce records in Greenhouse, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.

Intercom runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Greenhouse. Greenhouse is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.

Stacksync syncs Conversations, Tickets, Data Events, Custom Data Attributes in Intercom with Applications, Jobs, Offers, Scorecards in Greenhouse field by field, in real time, and in both directions. You decide which system owns which fields, so Greenhouse stays authoritative on roles and org structure while Intercom keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Push product usage events from an application database into Intercom to trigger onboarding and retention messages
  • 02 Mirror conversations and tickets into a warehouse for support analytics and SLA reporting
  • 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

Deactivate access when someone leaves

When Greenhouse marks a worker as departed, the matching user in Intercom is flagged or deactivated, so former employees do not keep CRM access after their last day.

One directory of people

A person's name, title, email, phone, or manager corrected in either system updates the other, so both stop maintaining separate copies of the same individual.

Where Greenhouse tracks people the business also engages: contacts stay in sync

A person recorded in Greenhouse, such as a candidate or applicant, can create or update the matching contact in Intercom, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.

What you can sync between Greenhouse and Intercom

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.

How changes propagate between Greenhouse and Intercom

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

Intercom Greenhouse Sub-second propagation

DetectionIntercom notifies Stacksync of record changes through webhook events. Webhook topic subscriptions for contact, company, and conversation events, plus polling for backfill.

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.
  • Intercom: Subject to per-app rate limits on the Intercom API.
