SMART on FHIR App Development Services
SMART on FHIR app development lets digital health vendors put their products directly inside the EHR, where clinicians already work. Taction Software builds EHR-embedded apps that launch with patient and user context, request only the scopes they need, and pass vendor reviews for distribution. We handle SMART App Launch, OAuth 2.0 authorization, FHIR data access and the practical steps toward listing with major EHR vendors. We also tell you honestly what takes time. Tell us about your app and get a realistic delivery plan.
What SMART on FHIR App Development Involves
SMART on FHIR is an open framework combining FHIR APIs with OAuth 2.0 authorization, so third-party apps can run securely with EHR data. A SMART app can launch inside the EHR with context already set, or run standalone for patients and providers. The same app can work across multiple EHRs that support the standard. Building one well requires attention to launch flows, scopes, user experience inside EHR frames and vendor-specific differences in implementation.
The SMART App Launch Framework
SMART App Launch defines how apps discover authorization endpoints, request permissions and receive tokens with context. It builds on OAuth 2.0 and OpenID Connect, which most development teams already understand.
EHR Launch
In EHR launch, a clinician opens your app from inside the EHR, and the app receives patient and encounter context automatically. Users skip extra logins and stay within their normal clinical workflow.
Standalone Launch
In standalone launch, users open your app directly, then authenticate with the EHR and select a patient if needed. This suits patient-facing apps and tools used outside the EHR interface.
Scopes and Context
Scopes define which data your app can read or write, such as patient-level Observation access. Requesting only necessary scopes speeds approvals and reduces risk if credentials are ever compromised. Justify each scope.
Working Across Multiple EHRs
SMART is a standard, but EHRs differ in supported scopes, resources and launch behavior. We build configuration layers, so one app adapts to each vendor without separate codebases or duplicated logic.
Our SMART on FHIR Integration Services
Our SMART on FHIR integration services cover the full path from architecture to production use at customer sites. We work with digital health vendors building new apps and with existing products adding EHR-embedded experiences. Every build includes secure token handling, audit logging and documentation for customer security reviews. Our FHIR integration development experience means your app handles real-world EHR data variations, not just clean sandbox test records. Our HIPAA compliant app development guide explains the baseline.
App Architecture and Design
We design apps for embedded use, including responsive layouts that fit EHR frames, fast load times and session handling that respects the EHR's context and timeout behavior for clinicians. Clinicians notice slow apps.
SMART Launch and Authorization
We implement EHR and standalone launch, PKCE, token refresh and secure storage. Credentials never appear in browsers or logs, and sessions end cleanly when users close the app or log out.
FHIR Data Access Layer
Using our healthcare API development patterns, we build a data layer that reads US Core resources efficiently, handles pagination and missing elements, and caches responsibly, so your app performs well even under vendor rate limits. Errors never block users.
Write-Back Where Supported
When your app needs to create notes, observations or documents in the EHR, we implement write-back where vendors allow it and design fallbacks where write access is unavailable or restricted.
Security and Compliance Controls
We apply HIPAA technical safeguards, including audit logging, encryption and least-privilege scopes, and prepare documentation answering typical hospital security questionnaires before your first customer asks for them. Reviews move faster as a result.
Listing Your App With EHR Vendors
Building the app is only part of EHR embedded app development. To reach customers at scale, most vendors require registration, technical review and sometimes marketplace listing before production use. These processes differ by vendor and change over time, so always check current program requirements directly. Listing timelines are controlled by EHR vendors and customers, and no agency can guarantee them. We help you prepare thoroughly, so reviews move as smoothly and predictably as possible.
Epic
Epic offers developer registration, sandbox access and a partner program with listing in its app marketplace, formerly App Orchard. Production use usually requires customer sponsorship and review by each health system's team.
Oracle Health (Cerner)
Oracle Health provides a code console for app registration, sandbox access and FHIR R4 APIs for Millennium. Customer-level approval and configuration are still needed before apps run in production environments.
Frequently Asked Questions
What is SMART on FHIR app development?
SMART on FHIR app development is building applications that securely access EHR data using FHIR APIs and the SMART App Launch framework, based on OAuth 2.0. These apps can launch inside the EHR with patient context or run standalone, and the same app can work across multiple EHRs supporting the standard.
What is the difference between EHR launch and standalone launch?
EHR launch starts your app from inside the EHR, automatically passing patient, user and encounter context, so clinicians skip extra logins. Standalone launch starts your app independently, then the user authenticates with the EHR and selects a patient if needed. Standalone suits patient-facing apps and tools used outside the EHR.
How long does it take to launch a SMART on FHIR app?
Development of a focused SMART app often takes two to four months. Vendor review, listing and customer security approval can add several weeks to several months, and these steps are controlled by vendors and health systems. Planning reviews in parallel with development helps protect realistic launch dates.
Can one SMART app work with Epic and Oracle Health?
Yes, SMART on FHIR is designed for portability. However, vendors differ in supported scopes, resources, launch behavior and review processes. A well-designed app uses a configuration layer to adapt to each EHR, avoiding separate codebases while handling vendor-specific differences reliably and predictably.
Can SMART on FHIR apps write data back to the EHR?
Sometimes. Write support is narrower than read support and varies by vendor and resource. Common write use cases include clinical notes, observations and documents. Confirm write capabilities for each target EHR before designing features that depend on writing data, and plan fallbacks where writes are restricted.
Do SMART on FHIR apps need to be HIPAA compliant?
Yes, if they create, receive, store or transmit protected health information on behalf of covered entities. That typically requires a Business Associate Agreement, audit logging, encryption, secure token handling and least-privilege scopes. Hospitals review these controls during onboarding, so build them in from the start.
