Healthcare API integration
over HL7 and FHIR, without the breakage.
Healthcare data does not move on its own. Patient records, lab results, scheduling, and billing sit in systems that were never built to talk to each other. Healthcare API integration connects them over HL7 and FHIR, and HighCraft handles the parts that usually break: patient matching, data mapping, and keeping records in sync.
Scoped estimate in 3 to 5 days. No obligation, NDA on request.
“They were absolutely phenomenal. The team put in a lot of work to break down what was required of the project and gave an excellent presentation on the process. I highly recommend them and will be working with them again in the future.”

Who you work with
We wire the systems that were never meant to talk
HighCraft is a senior team that pairs full-stack engineering with applied AI for healthcare, SaaS, and expert-led businesses. We have earned Top Rated and a 100 percent Job Success Score on Upwork since 2023, one five-star delivery at a time, before growing to a team of six.
We built a HIPAA-aligned EMR and patient portal for a healthcare wellness platform, including the connectors that move clinical and billing data between systems. You work with the engineers who wrote those integrations, not a sales layer in front of them.

engineers, no handoffs
Interoperability sounds standardized until you connect two real systems. Different versions, custom fields, and edge cases the spec never anticipated. We build to the FHIR specification standard and handle the messy reality around it: terminology mapping, patient matching, and the legacy HL7 v2 feeds that are not going away.

AI Prototype Sprint
Validate the workflow before you fund the platform.
A four-week sprint that turns a complex workflow into a clickable prototype, architecture direction, and a build estimate you can act on.
- Clickable prototype
- Workflow map
- Architecture recommendation
- AI opportunity and risk assessment
- Delivery roadmap
- Fixed or phased build estimate
Four weeks, one fixed scope. You own everything we build, whether or not you continue.
Week 1
Discover the real workflow
Week 2
Build the spine
Week 3
AI where it pays back
Week 4
Prototype + estimate
Engagement models
Four ways to engage, and a low-risk way to start
We fit the model to the project and the risk, not to our invoice. Most clients start with a four-week discovery sprint that turns the idea into a working prototype and a real estimate, then move into whichever model fits the build.
Time and materials
You pay for the hours you use, billed weekly or monthly. The right call when scope is still moving and you want to steer as you go.
Dedicated team
A senior team embedded with yours and billed monthly, scaling up or down as the roadmap changes. Built for ongoing work, not a one-off.
Fixed price
Agreed scope, agreed price, agreed date. Works when the requirements are already clear and you want certainty before you sign.
Fixed milestones
Phased delivery, paid one milestone at a time. A way to take on a larger build and de-risk it stage by stage.
What clients say
Clients trust us with messy, real-world software
From regulated healthcare workflows to payment-heavy platforms and internal business systems, the common thread is delivery that survives production.
They demonstrated their dedication to our project from the beginning, and I am pleased with the final result. For anyone looking to develop a software product that requires meticulous attention to detail and regulatory compliance, HighCraft.io is the partner you need.

HighCraft team did a great job creating a brand new site for my company, and I am loving it. It is exactly what I wanted and the team were true professionals and very nice to work with.

What we do
Three ways we turn complex workflows into working software
Start with a prototype, add AI where it creates leverage, or build the full production platform.
Working prototypes
A clickable prototype built around the real edge cases, so you can validate scope before funding a full build. The cheapest way to find the edge case nobody mentioned.
AI-enabled features
AI inside the product you already run: intake, search, summarization, classification, recommendations, or workflow assistance, with evaluation and guardrails. Built so a real user opens it twice.
Production platforms
Custom .NET, Azure, React, and Angular platforms built for real users: integrations, permissions, billing, audit trails, and maintenance. HIPAA-aware where it has to be.
Related services
Part of the same healthcare build
If your project touches more than one of these, one team covers them.
Client work
Software that works, in production
Our clients get to focus on their business, instead of babysitting the stack that holds it together. The work below is anonymized: a healthcare wellness platform, no logo, just the architecture.

How we build
How we build AI workflows that stay controllable
Agentic does not have to mean opaque. We put the controls where the risk is: permissions, approvals, and audit around every AI-assisted step.
Frontend
The product your users and staff actually work in.
API
Typed contracts and validation at the boundary.
Workflow engine
The deterministic spine: states, rules, and handoffs.
Agentic workflow layer
Inspects context, suggests next steps, and triggers tools, with human approval where it matters.
AI / LLM services
Models behind evaluation and fallback logic, not raw and unchecked output.
Integrations
EMR, Stripe, CRM, scheduling, and internal APIs.
Audit, monitoring, permissions
Every AI-assisted step logged, observable, and role-gated.
Controls, not black boxes
- Human approval for sensitive actions
- Tool calls scoped by permissions
- Audit logs for every AI-assisted step
- Evaluation and fallback logic, not raw model output
- Role-based access throughout
- Observability in production
- Integration with EMR, Stripe, CRM, scheduling, or internal APIs
FAQ
Hiring a healthcare API integration team
What buyers ask before they start.
Most engagements here start with an AI Prototype Sprint or a scoped production build.
What is healthcare API integration?
It is the work of getting healthcare systems to share data. EHRs, lab systems, scheduling, billing, and devices each hold a piece of the picture. Integration connects them over standards like HL7 v2 and FHIR, plus REST APIs, so a record updated in one place shows up correctly everywhere it should.
Can you integrate with Epic, Cerner, or athenahealth?
Yes, through their published APIs and interface programs, over FHIR or HL7 depending on what the system exposes. The timeline often depends on the vendor approval and sandbox access more than the code, and we will tell you where that path is slow before you commit.
Do we need HL7 v2 or FHIR?
Usually both, for a while. FHIR is where modern systems are heading, but a lot of real clinical data still moves over HL7 v2 feeds that are not retiring soon. We bridge the two so you are not forced to rip out the old to adopt the new.
Can you integrate labs and medical devices?
Yes. We bring in lab results coded to LOINC and device data feeds, normalize them, and land them in the record where a clinician can actually use them. The hard part is rarely the connection, it is making the data clean and consistent once it arrives.
How much does healthcare API integration cost?
Send the systems you need connected and we reply with a scoped estimate, usually within 3 to 5 business days. Cost tracks the number of systems, whether each exposes a modern API, and how much data cleanup the integration carries.
When are you not the right fit?
If an off-the-shelf integration engine or a pre-built connector already covers your systems, we will point you there instead of quoting custom work. We are the right call when the standard connectors stop at the edge of your actual workflow.
