Why teams connect Greenhouse and Streak CRM

Keep the people who own accounts in Streak 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.

Streak 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 Pipelines, Boxes, Stages, Contacts in Streak 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 Streak CRM keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Sync Streak boxes into Postgres so operations can query pipeline data with SQL and back internal tools
  • 02 Push deals and contacts into a warehouse to report on pipeline alongside product and billing data
  • 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 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 Streak 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 Streak CRM, so a new rep can start working accounts without waiting on a manual setup ticket.

What you can sync between Greenhouse and Streak CRM

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

Streak CRM Greenhouse Interval-based propagation

DetectionStacksync polls Streak CRM for changes on an incremental schedule, reading only records changed since the previous pass. Polling against pipeline, box, and contact endpoints.

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.
  • Streak CRM: Subject to the platform's API rate limits; quotas are not prominently published.
