Why teams connect Greenhouse and Twenty CRM

Keep the people who own accounts in Twenty CRM 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.

Twenty CRM 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 Companies, Opportunities, Tasks, Notes in Twenty CRM with Candidates, Applications, Jobs, Offers 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 Twenty CRM keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Sync Opportunities into a finance system to keep revenue forecasts current.
  • 02 Mirror support tickets or tasks between Twenty and an operations tool.
  • 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

Deactivate access when someone leaves

When Greenhouse marks a worker as departed, the matching user in Twenty CRM 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 Twenty CRM, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.

What you can sync between Greenhouse and Twenty CRM

How changes propagate between Greenhouse and Twenty CRM

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 Twenty CRM 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 Twenty CRM 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.
  • Twenty CRM: Subject to the platform's API rate limits; self-hosted deployments control their own limits.
