Before automating anything in a healthcare practice, you need to know what your EHR will actually let you do. The platforms differ significantly in how accessible their data is and what integrations they'll support.
Athenahealth
Athenahealth's API documentation covers resources for patients, appointments, encounters, documents, claims, and other workflows. Production access still depends on the endpoint, scopes, customer context, and commercial terms. Verify the exact read and write operations the project needs.
Epic
Epic publishes FHIR resources and implementation steps through Epic on FHIR. An app still has to register correctly and be enabled in the customer's Epic environment. Available resources, scopes, and write operations depend on the use case and health system; there is no single "full Epic API" permission.
eClinicalWorks
eClinicalWorks publishes FHIR R4 documentation for patient-facing, provider-facing, and bulk/backend access. Its current certification disclosure also notes configuration, enablement, rate limits, and possible fees. Scheduling, billing, and write requirements must be checked separately from the certified read APIs.
Dentrix (dental)
Dentrix has an approved developer program with read, write, scheduling, and claims-summary API categories. For the on-premise product, the integration runs locally and uses approved API or ODBC access. The Dentrix developer FAQ explains the access and approval model. Dentrix Ascend has a separate cloud API program.
Eaglesoft, Tebra, and other platforms
Do not assume one product's access model applies to another. Ask the vendor for its current developer documentation, production approval process, supported resources, write operations, event or webhook support, fees, and BAA terms. If those cannot be verified before scoping, treat the integration as an open dependency.
What this means for planning
Your EHR shapes what's possible. Before scoping an automation project, inspect its current documentation and capability statement, then confirm production access with the customer and vendor.
If the EHR supports only approved data exports, a scheduled export may still feed reporting or staff alerts. It will not provide real-time writeback, and its timing and permitted use depend on the export.
If you're evaluating EHR platforms and automation matters to your practice, API accessibility should be on your checklist alongside clinical features and cost.
