Why teams connect Copper CRM and Greenhouse

Keep the people who own accounts in Copper 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.

Copper 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 Opportunities, Activities, Tasks, Projects in Copper CRM with Offers, Scorecards, Scheduled Interviews, Users 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 Copper CRM keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Mirror Copper data into Postgres so internal tools can query CRM state without extra API calls.
  • 02 Sync Copper people and opportunities into a warehouse for pipeline reporting beyond Copper's native dashboards.
  • 03 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.
  • 04 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.

Common sync patterns

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 Copper CRM, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.

New team members provisioned when they are hired

When Greenhouse records a new hire, a matching user or owner is created in Copper 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 Copper CRM update to match, so pipeline stays with the right owner.

How changes propagate between Copper 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.

Copper CRM Greenhouse Sub-second propagation

DetectionCopper CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record create/update/delete events.

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

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

Rate-limit considerations

  • Copper 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.
