Why teams connect Greenhouse and Vtiger CRM

Keep the people who own accounts in Vtiger 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.

Vtiger 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 Campaigns, Contacts, Organizations, Leads in Vtiger 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 Vtiger CRM keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Mirror Leads and Campaigns to an email platform to keep marketing lists current.
  • 02 Two-way contact and organization sync between Vtiger and a billing or ERP system.
  • 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

New team members provisioned when they are hired

When Greenhouse records a new hire, a matching user or owner is created in Vtiger 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 Vtiger 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 Vtiger CRM is flagged or deactivated, so former employees do not keep CRM access after their last day.

How changes propagate between Greenhouse and Vtiger CRM

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.
  • Vtiger CRM: Subject to the platform's API rate limits, which vary by edition.
