Why teams connect eClinicalWorks and PostgreSQL

Mirror eClinicalWorks's data into PostgreSQL so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like eClinicalWorks through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in PostgreSQL.

Stacksync mirrors Encounters, Practitioners, Observations, Medications from eClinicalWorks into Materialized Views, Schemas, Columns, Primary and Unique Keys in PostgreSQL and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into eClinicalWorks, so the tool and the database never disagree.

Common use cases

  • Land encounter and billing-context data in a warehouse for utilization and revenue-cycle reporting.
  • Feed appointment events to reminder and messaging platforms to reduce no-shows.
  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • Let an application write to its own database and have those rows appear as records in business systems in near real time

Read eClinicalWorks with a query

Records from eClinicalWorks are ordinary rows in PostgreSQL; join them, index them, and use them in application logic without touching the vendor API.

Automate eClinicalWorks from your codebase

Write to the synced tables in PostgreSQL and Stacksync propagates the change into eClinicalWorks, replacing custom integration code.

React to changes as they happen

Updates in eClinicalWorks arrive as row changes in PostgreSQL, so triggers, jobs, and services can respond in near real time.

What you can sync between eClinicalWorks and PostgreSQL

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 PostgreSQL objects
Allergies Allergy and intolerance entries in the clinical record. Sequences Generate surrogate keys for rows created by inbound syncs.
Immunizations Vaccination history exposed for registries and patient apps. Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields.
Documents Clinical notes and attachments referenced from the chart. Tables The primary sync target; rows map one-to-one to records in connected SaaS systems.
Diagnostic reports Structured result reports grouping observations for a study or panel. Views Read-side projections used to expose joined or filtered data to a sync.
Patients Demographic records exposed via FHIR Patient resources and HL7 ADT feeds; the anchor for all clinical syncs. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Schemas Namespaces that scope which tables a sync reads and writes.

At scale

Event queues

Handle millions of events per minute without losing a single eClinicalWorks or PostgreSQL record.

Observability

Monitoring

Track your eClinicalWorks ⇄ PostgreSQL sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between eClinicalWorks and PostgreSQL.

How the eClinicalWorks and PostgreSQL connectors work

eClinicalWorks

Integration surface
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
Change detection
HL7 interface feeds push event messages as they occur; the FHIR API is polled
Capabilities
read · write
Rate limits
Subject to the platform's API rate limits and interface throughput agreements

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
Change detection
Logical replication (wal_level = logical) for change data capture via the "Postgres" connector; database triggers (TRIGGER grant + stacksync_logging schema) via the trigger-based "Postgres Heroku" connector where
Capabilities

How it works

How to connect eClinicalWorks to PostgreSQL — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate eClinicalWorks and PostgreSQL with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
