eClinicalWorks API
Certified FHIR R4 APIs with SMART on FHIR OAuth are free on two portals, one provider-facing and one patient-facing via healow, with open synthetic-data sandboxes. Production still needs per-practice enablement, and anything beyond the USCDI subset is a negotiated commercial interface.
Frequently asked questions
eClinicalWorks scores F on the API Report Card. Certified FHIR R4 APIs with SMART on FHIR OAuth are free on two portals, one provider-facing and one patient-facing via healow, with open synthetic-data sandboxes. Production still needs per-practice enablement, and anything beyond the USCDI subset is a negotiated commercial interface.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
eClinicalWorks (eCW) is a privately held healthcare IT vendor that sells a unified, cloud-based Electronic Health Record (EHR), Practice Management (PM), and Revenue Cycle Management (RCM) suite to ambulatory practices.
Vertical: Healthcare (ambulatory EHR + practice management + revenue cycle management). Front-office staff use eCW for patient registration, eligibility/benefits verification, scheduling, check-in, copay collection (often via healow Pay), and document imaging.
9/10, eClinicalWorks is one of the top three ambulatory EHR vendors in the United States and the largest privately held EHR company in the country.
Yes, eClinicalWorks is the system of record for essentially every clinical and financial transaction inside a practice running it.
Founded 1999 in Westborough, Massachusetts by Girish Navani, Sunil Wadhwani, and Mahesh Navani. eClinicalWorks remains privately held and founder-led, with Navani still CEO, a rarity among legacy EHR vendors, which have mostly been acquired or PE-rolled.
Production FHIR access still requires per-practice enablement on the eCW side, even a certified app cannot just connect to a customer's data without eCW-side activation. Proprietary (non-FHIR) integrations, HL7 v2, custom extracts, bidirectional PM/RCM feeds, are negotiated commercially per integration with fees, slowing third-party developer adoption.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial eClinicalWorks API and MCP server so AI agents and internal tools can read and write eClinicalWorks data. See the eClinicalWorks integration docs at supergood.ai/docs/eclinicalworks-api.
