TecXra is a full-cycle, AI-powered software company building web and mobile applications, HIPAA-ready healthcare platforms, MVPs and SaaS products for startups and enterprises.
Connect your product to the systems your clinicians already use. TecXra builds FHIR, HL7 and API integrations with HIPAA safeguards designed in from the first sprint.
A product that cannot read and write clinical data inside the EHR rarely survives in a hospital or practice. Every EHR vendor has its own APIs, access program and approval process, even though most now support the HL7 and FHIR standards. Under the 21st Century Cures Act, certified EHRs must offer standardized FHIR APIs, which makes integration far more practical than it used to be, but each system still needs its own plan. Our healthcare software team has hands-on experience across Epic, Cerner, athenahealth and Meditech.
We build on HL7 v2, FHIR R4 and SMART on FHIR so your integration works across systems, not just one.
Every EHR has its own developer program, sandbox and approval path. We scope that early so it does not stall your launch.
Encrypted storage, role-based access, audit logging and BAAs with infrastructure providers, from the first sprint.
These five platforms cover a large share of US hospitals and ambulatory practices. Here is how each one works and what a typical integration involves.
Large health systems and academic medical centers. FHIR APIs, SMART on FHIR and HL7 v2 interfaces.
Hospitals on Oracle Health Millennium. FHIR R4 APIs, code Console app registration and a sandbox.
Ambulatory practices and medical groups on athenaOne. 800+ API endpoints, HL7 and C-CDA interfaces.
Hospitals running MEDITECH Expanse. SMART on FHIR testing and partner programs through Greenfield.
Ambulatory practices on eClinicalWorks. FHIR R4 API with US Core profiles and OAuth 2.0 / SMART on FHIR.
Epic is the EHR many large health systems and academic medical centers run. Epic’s developer site, open.epic.com, publishes a large library of APIs, including FHIR APIs, and Epic Showroom is where Epic customers discover third-party products that work with Epic. Apps that run inside the clinician workflow typically use SMART on FHIR, and data exchange uses FHIR APIs and HL7 v2 interfaces.
Cerner is now part of Oracle Health. Its Millennium platform exposes FHIR R4 APIs. Developers create an application in Oracle Health’s code Console, test it in a nonproduction sandbox, and then work with each customer, who provisions the application against their own tenant through a service request.
athenahealth’s cloud platform, athenaOne, is used by ambulatory practices and medical groups. athenahealth offers over 800 API endpoints for extending the platform, HL7 and C-CDA interfaces for exchanging clinical data, and a Marketplace Partners Program that helps promote and distribute integrated apps.
MEDITECH’s Expanse EHR is used by hospitals of many sizes, including community hospitals. MEDITECH’s Greenfield initiative has two parts: Greenfield Workspace, a development environment where app developers can test solutions, including SMART on FHIR apps, in a real MEDITECH EHR, and Greenfield Alliance, for partners with proven products that complement or extend Expanse.
eClinicalWorks (eCW) is a widely used ambulatory EHR. It exposes a FHIR R4 API built on US Core profiles, secured with OAuth 2.0 under SMART on FHIR. You register an application in the eClinicalWorks developer program, which issues a client ID, and then each practice must authorize your app in its own environment, so build lead time into your plan.
A quick comparison of the five systems. Details vary by customer deployment, so we confirm the exact scope with each organization.
| System | Typical setting | APIs and standards | How access works |
|---|---|---|---|
| Epic | Large health systems, academic medical centers | FHIR APIs, SMART on FHIR, HL7 v2 | Epic developer program (open.epic.com), then customer approval |
| Oracle Health (Cerner) | Hospitals and health systems on Millennium | FHIR R4, SMART on FHIR, HL7 v2 | code Console app, sandbox, customer provisions app on their tenant |
| athenahealth | Ambulatory practices, medical groups | 800+ REST endpoints, HL7, C-CDA, FHIR | Developer portal and Marketplace Partners Program |
| MEDITECH | Hospitals on Expanse, including community hospitals | FHIR, SMART on FHIR, HL7 | Greenfield Workspace and Greenfield Alliance |
| eClinicalWorks | Ambulatory practices and groups | FHIR R4 (US Core), OAuth 2.0, SMART | Developer registration, then practice-by-practice authorization |
A clear process with clinical review built in, so you always know what is happening and what comes next.
Pick the target EHRs, the data you need and the approval path for each, before any code is written.
FHIR and HL7 mapping, SMART on FHIR apps and secure data sync, built in two-week sprints.
Sandbox testing against real clinical scenarios, with clinical stakeholder review gates.
Compliant deployment, audit logging and hands-on support through the first weeks.
EHR integration connects your software to an electronic health record system so data such as patients, appointments, medications and results can be read and, where permitted, written securely. It uses standards such as HL7 v2 and FHIR, and each EHR vendor adds its own access program.
TecXra has hands-on experience with Epic, Cerner (Oracle Health), athenahealth and Meditech, and we scope eClinicalWorks integrations around its FHIR R4 API. We use HL7, FHIR APIs and custom connectors depending on what each system supports.
Each system has its own access requirements and approval timelines, and customers often have their own steps too. We scope this early and guide you through each system's process, so access does not become a surprise late in the project.
It depends on the systems and data involved. FHIR R4 is the modern standard and most major EHRs offer FHIR APIs, but many hospitals still exchange data over HL7 v2 interfaces. We design the integration layer to support the standards your customers actually use.
HIPAA compliance depends on how the whole system is built and operated. We design with encrypted storage, role-based access controls, audit logging and BAAs with cloud infrastructure providers, and your own compliance team or counsel should confirm the final setup.
Yes, through approved APIs. For example, our healthcare AI agent case study shows an agent that books appointments and answers insurance questions, with a clear hand-off to staff for anything clinical.
