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 Supergood's 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. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
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.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
eClinicalWorks has partial MCP support. eClinicalWorks publishes no official MCP server, but a community server wraps the eClinicalWorks/healow FHIR R4 API with SMART on FHIR auth and read access to patient clinical data, with public install docs and activity within the last six months. It is read only, covers only the FHIR surface, and has minimal adoption so far.
Partially. MCP support for eClinicalWorks exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
