Can you integrate eClinicalWorks with ServiceNow?

Yes. Stacksync provides a managed, real-time two-way integration between eClinicalWorks and ServiceNow: authenticate both systems, choose the objects to sync (such as eClinicalWorks's Appointments and Encounters), map fields visually, and changes propagate both ways in milliseconds — no code required.

Can the eClinicalWorks–ServiceNow sync run one-way instead of two-way?

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

How do teams use the eClinicalWorks and ServiceNow integration?

Common patterns for eClinicalWorks and ServiceNow: Handoffs between teams; Where both tools track people or companies: one consistent record; Where one tool produces events: mirror them in the other. When work started in one tool continues in the other, the shared fields travel with it automatically.

What should I know about the two APIs?

eClinicalWorks: FHIR R4 REST API plus HL7 v2 interfaces (ADT, SIU, ORU) through an interface engine. Authentication: OAuth 2.0 / SMART on FHIR for the FHIR API; site-configured credentials for HL7 interface connections. ServiceNow: REST API (Table, Import Set, and Aggregate APIs); SOAP remains for legacy integrations. Authentication: OAuth 2.0 or basic authentication against the instance. Stacksync manages authentication, retries, and rate limits on both sides.

What makes eClinicalWorks's data model different?

eClinicalWorks: All patient data is PHI, so integrations must run under HIPAA business associate agreements with appropriate access controls. ServiceNow: Sys_updated_on and sys_created_on columns exist on every table, giving a consistent basis for incremental extraction. Stacksync's field mapping accounts for these differences between eClinicalWorks and ServiceNow without custom code.

Is the eClinicalWorks–ServiceNow integration secure?

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means eClinicalWorks and ServiceNow records are not retained after a sync operation.

Why teams connect eClinicalWorks and ServiceNow

Stop re-entering the same information in eClinicalWorks and ServiceNow: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Diagnostic reports, Patients, Appointments, Encounters in eClinicalWorks with Custom Tables, Incidents, Change Requests, Problems in ServiceNow in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

Push referral or intake data captured in external forms into the EHR via HL7 interfaces.
Sync patient demographics and appointments into a CRM so patient outreach and intake teams work from current data.
Sync sys_user records with the HR system or identity provider so assignment groups stay accurate
Mirror incident and task data into Postgres or a warehouse for SLA and workload reporting

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

What you can sync between eClinicalWorks and ServiceNow

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		ServiceNow objects
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach.	⇄	Knowledge Articles Support content that can be mirrored to help centers or search indexes.
Encounters Visit records tying diagnoses, providers, and billing context together.	⇄	Custom Tables Scoped or u_-prefixed tables are addressable through the same Table API as standard ones.
Practitioners Provider records used to keep directories and scheduling systems consistent.	⇄	Incidents The core ITSM ticket; commonly synced with engineering trackers and CRMs.
Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages.	⇄	Change Requests Track planned changes; synced to deployment and release tooling.
Medications Prescription and medication-list data within the patient record.	⇄	Problems Root-cause records linked to incidents, useful in cross-system reporting.
Allergies Allergy and intolerance entries in the clinical record.	⇄	Service Catalog Requests Requested items and approvals that often trigger provisioning in other systems.
