Why teams connect Folk CRM and Greenhouse

Keep the people who own accounts in Folk 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.

Folk 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 Notes, Reminders, People, Companies in Folk CRM with Scorecards, Scheduled Interviews, Users, Departments and Offices 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 Folk CRM keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Push enriched contact data from a data warehouse into folk custom fields.
  • 02 Mirror folk groups into a reporting database to track pipeline and outreach coverage.
  • 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

New team members provisioned when they are hired

When Greenhouse records a new hire, a matching user or owner is created in Folk CRM, so a new rep can start working accounts without waiting on a manual setup ticket.

Ownership and territory follow the org chart

When a person changes team, manager, or region in Greenhouse, their accounts and territory assignments in Folk CRM update to match, so pipeline stays with the right owner.

Deactivate access when someone leaves

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

How changes propagate between Folk CRM 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.

Folk CRM Greenhouse Sub-second propagation

DetectionFolk CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling of list endpoints as a fallback.

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

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

Rate-limit considerations

  • Folk CRM: Subject to the platform's API rate limits.
  • 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.
