Why teams connect ConnectWise and Greenhouse

Keep the people, teams, and status that ConnectWise and Greenhouse share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in ConnectWise keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Greenhouse is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.

Stacksync syncs Opportunities, Agreements, Projects, Time Entries in ConnectWise with Applications, Jobs, Offers, Scorecards in Greenhouse bi-directionally and in real time. A person added, moved, or offboarded in Greenhouse creates or updates the matching user in ConnectWise within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where ConnectWise captures details of its own, such as a corrected contact or a login identity, those can flow back to Greenhouse in whichever direction you configure.

Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.

Common use cases

  • 01 Push closed-won opportunities from the CRM into ConnectWise to kick off agreements and onboarding projects.
  • 02 Reconcile ConnectWise invoices and agreements against the accounting system to catch billing gaps.
  • 03 Stream Jobs, Departments, and Offices into a reporting database for recruiting funnel and time-to-fill dashboards.
  • 04 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.

Common sync patterns

Offboarding: no standing access after a departure

When someone is marked as leaving in Greenhouse, the matching account in ConnectWise is deactivated or flagged, so departures do not leave open access behind.

One employee directory

A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.

Org and team structure kept current

Department, team, and reporting-line changes from Greenhouse keep the groups, queues, or projects in ConnectWise assigned to the right people.

How changes propagate between ConnectWise 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.

ConnectWise Greenhouse Sub-second propagation

DetectionConnectWise notifies Stacksync of record changes through webhook events. Callbacks (webhooks) on record changes, supplemented by polling on last-updated fields.

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

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

Rate-limit considerations

  • ConnectWise: Subject to the platform's API rate limits per company and integration.
  • 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.
