**APIs profiled:** 3

eClinicalWorks is a cloud-based EHR and practice-management platform serving more than 180,000 physicians and 850,000 medical professionals. Its API surface is standards-based rather than proprietary: FHIR R4 served by the eCW FHIR Facade behind SMART on FHIR and OAuth 2.0, split across a provider-facing facade (fhir4.eclinicalworks.com) and a patient-facing healow facade (fhir4.healow.com), each tenant-scoped by a six-character practice code. eClinicalWorks publishes no OpenAPI; the machine-readable contract is the FHIR CapabilityStatement at each tenant's /metadata plus the SMART configuration at /.well-known/smart-configuration, which advertises 486 scopes. Capabilities include SMART EHR Launch and Standalone Launch, Backend Services with Group/$export bulk data, CDS Hooks, a documented writeback catalogue, patient-facing healow Clinical and Scheduling APIs, and a bidirectional healow RPM Vendor (Tracker) API for remote-monitoring device orders and observations. APIs are certified to the ONC 45 CFR 170.315(g)(10) Standardized API for Patient and Population Services criterion.
