Hi everyone,
I am trying to build a healthcare application using FHIR and OpenAI Realtime API with a low-code/no-code platform.
My goal is to:
- Connect FHIR patient data securely
- Use OpenAI Realtime features for live conversation or voice interaction
- Build workflows with minimal coding
- Possibly integrate tools like webhooks, APIs, or automation platforms
I would like guidance on:
- Best low-code platforms for OpenAI Realtime integration
- How to connect FHIR resources (Patient, Observation, Encounter, etc.)
- Authentication and security best practices
- Example architecture or workflow
- Any sample projects or tutorials
Has anyone implemented a similar solution in healthcare?
Any recommendations, examples, or documentation would be very helpful.
Thanks
Yes, this is very possible with OpenAI Realtime API + FHIR + low-code tools.
A simple architecture is:
FHIR Server (Epic/Cerner/HAPI FHIR)
→ Low-code platform (n8n, Retool, Make)
→ OpenAI Realtime API
→ Web/mobile voice app
Best low-code tools:
n8n — great for webhooks and OpenAI workflows
Retool — good for healthcare dashboards/apps
Make — easy automation workflows
Bubble — full no-code frontend apps
FHIR integration:
Use REST APIs for resources like Patient, Observation, Encounter
Example:
GET /Observation?patient=123
Recommended security:
SMART on FHIR + OAuth2
Keep OpenAI keys on backend only
Encrypt PHI data
Add audit logging
Typical workflow:
User asks a question by voice
Realtime API triggers a webhook/tool
Workflow fetches FHIR data
AI responds naturally
Useful docs:
OpenAI Realtime API Docs
FHIR Specification
SMART on FHIR
For an MVP, I’d recommend:
Bubble or Retool + n8n + HAPI FHIR + OpenAI Realtime API.
