Why teams connect Greenhouse and Zoho CRM

Keep the people who own accounts in Zoho 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.

Zoho 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 Purchase Order, Invoice, Lead, Contact in Zoho CRM with Users, Departments and Offices, Candidates, Applications 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 Zoho CRM keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Run Zoho CRM and another CRM in parallel with bi-directional sync during a migration.
  • 02 Push warehouse-computed lead scores and product signals into Zoho CRM fields for rep prioritization.
  • 03 Write enriched or sourced Candidates from external tools into Greenhouse and keep contact fields refreshed as data changes.
  • 04 Stream Jobs, Departments, and Offices into a reporting database for recruiting funnel and time-to-fill dashboards.

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 Zoho 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 Zoho CRM, so a new rep can start working accounts without waiting on a manual setup ticket.

How changes propagate between Greenhouse and Zoho 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 Zoho 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 Zoho CRM through its API, with automatic retries and rate-limit backoff.

Zoho CRM Greenhouse Sub-second propagation

DetectionZoho CRM notifies Stacksync of record changes through webhook events. Notification API (webhooks) on watched modules, with polling on Modified_Time.

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.
  • Zoho CRM: API credits are allocated per day and vary by edition.
