Why teams connect eClinicalWorks and Snowflake

Get the data locked inside eClinicalWorks into Snowflake as live tables, and send results back where eClinicalWorks can use them, without writing a pipeline.

Whatever eClinicalWorks is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Documents, Diagnostic reports, Patients, Appointments from eClinicalWorks into tables in Snowflake continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Snowflake can also be written back into fields in eClinicalWorks where the tool can use them.

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.
  • Feed finance reconciliation models from ERP data landed in Snowflake on a continuous basis
  • Land CRM and ERP records in Snowflake continuously so BI reflects business systems without nightly batch ETL

History that outlives the tool

A continuously synced copy in Snowflake preserves a queryable record even as data ages out of eClinicalWorks or gets changed inside it.

Analytics on eClinicalWorks's data

Records and events from eClinicalWorks land in Snowflake as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine eClinicalWorks's data with data from every other synced system to answer questions no single tool can.

What you can sync between eClinicalWorks and Snowflake

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 Snowflake objects
Practitioners Provider records used to keep directories and scheduling systems consistent. Stages File staging areas used for bulk loads into synced tables.
Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages. Tasks Scheduled SQL used to transform synced data after it lands.
Medications Prescription and medication-list data within the patient record. VARIANT Columns Semi-structured JSON payloads stored alongside relational columns.
Allergies Allergy and intolerance entries in the clinical record. Virtual Warehouses The compute a sync's queries run on, sized independently of storage.
Immunizations Vaccination history exposed for registries and patient apps. Databases Top-level containers that scope which data a sync can touch.
Documents Clinical notes and attachments referenced from the chart. Schemas Namespaces within a database used to organize synced tables.

How the eClinicalWorks and Snowflake 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

Snowflake

Integration surface
SQL via JDBC/ODBC and native drivers, plus the Snowflake SQL REST API
Authentication
Dedicated Snowflake service user + role with RSA key-pair authentication (Stacksync-provided public key), created via a setup script requiring SECURITY_ADMIN and ACCOUNTADMIN roles
Change detection
Not explicitly stated; the setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism
Capabilities
read · write · CDC
Rate limits
No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time
