Why teams connect eClinicalWorks and Greenhouse

Keep the people, teams, and status that eClinicalWorks 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 eClinicalWorks 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 Practitioners, Observations, Medications, Allergies in eClinicalWorks with Scorecards, Scheduled Interviews, Users, Departments and Offices in Greenhouse bi-directionally and in real time. A person added, moved, or offboarded in Greenhouse creates or updates the matching user in eClinicalWorks within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where eClinicalWorks 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 Land encounter and billing-context data in a warehouse for utilization and revenue-cycle reporting.
  • 02 Feed appointment events to reminder and messaging platforms to reduce no-shows.
  • 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 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 eClinicalWorks assigned to the right people.

Where eClinicalWorks routes or assigns work by person: assignments follow the org

When someone changes teams or managers in Greenhouse, the queues, ownership, or approvals in eClinicalWorks update to match, so work reaches whoever holds the role now.

What you can sync between eClinicalWorks and Greenhouse

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.

eClinicalWorks objects Greenhouse objects How this pairing syncs
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Appointments is specific to eClinicalWorks and Users to Greenhouse — each maps to any object or custom field on the other side.
Encounters Visit records tying diagnoses, providers, and billing context together. Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. Encounters is specific to eClinicalWorks and Departments and Offices to Greenhouse — each maps to any object or custom field on the other side.
Practitioners Provider records used to keep directories and scheduling systems consistent. Candidates Person records with contact details, tags, and custom fields; read and written via Harvest, often created from sourcing or enrichment pipelines. Practitioners is specific to eClinicalWorks and Candidates to Greenhouse — each maps to any object or custom field on the other side.
Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages. Applications Links a Candidate to a Job; carries current stage, status, and source. Movable, rejectable, and hireable through Harvest write calls. Observations is specific to eClinicalWorks and Applications to Greenhouse — each maps to any object or custom field on the other side.
Medications Prescription and medication-list data within the patient record. Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. Medications is specific to eClinicalWorks and Jobs to Greenhouse — each maps to any object or custom field on the other side.
Allergies Allergy and intolerance entries in the clinical record. Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. Allergies is specific to eClinicalWorks and Offers to Greenhouse — each maps to any object or custom field on the other side.

How changes propagate between eClinicalWorks 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.

eClinicalWorks Greenhouse Interval-based propagation

DetectionStacksync polls eClinicalWorks for changes on an incremental schedule, reading only records changed since the previous pass. HL7 interface feeds push event messages as they occur.

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

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

Rate-limit considerations

  • eClinicalWorks: Subject to the platform's API rate limits and interface throughput agreements.
  • 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.
