Learn moreWhy FHIR matters
HL7® FHIR® (Fast Healthcare Interoperability Resources) is a standard developed and maintained by HL7 International. It models clinical and administrative data as discrete, well-defined resources — Patient, Observation, Encounter, MedicationRequest and many more — and exposes them through a RESTful API using JSON or XML.
Because FHIR uses the same web technologies developers already know, applications can read and write health data far more easily than with older message-based standards like HL7 v2. Implementation guides such as US Core constrain FHIR for specific regions and use cases, so systems agree not just on format but on meaning.
In the United States, regulations including the 21st Century Cures Act and CMS interoperability rules have made standardized FHIR APIs central to patient access, payer data exchange and EHR certification — which is why choosing the right FHIR partner has become a strategic decision.
Shared resource definitions, terminologies and profiles reduce custom point-to-point mapping.
RESTful APIs, Bulk Data export and subscriptions support everything from single records to population data.
Patients can connect apps of their choice to retrieve their records through certified FHIR APIs.
SMART on FHIR lets third-party apps launch securely inside EHR workflows using OAuth 2.0.
Buyer's checklist
Use these criteria to structure vendor conversations and RFPs. Ask for evidence — documentation, test results, references — not just claims.
Confirm which versions (R4, R4B, R5) and implementation guides — such as US Core — the vendor supports in production, not just on a roadmap.
Ask for comparable projects, including HL7 v2 and C-CDA coexistence, terminology mapping and profile validation.
Check support for EHR and standalone launch, granular scopes, PKCE and SMART Backend Services for system-to-system access.
Review their approach to HIPAA safeguards, audit logging, encryption, penetration testing and willingness to sign a BAA.
Look for hands-on experience with the specific EHRs you run, including app registration, sandbox access and customer-specific enablement.
Discuss search performance, paging, Bulk Data export, rate limits and how the solution behaves at your expected data volumes.
Clarify SLAs, upgrade policies for new FHIR versions and EHR API changes, monitoring and who owns incidents after go-live.

Find a FHIR PartnerResources
FHIR is the HL7 standard for exchanging healthcare data through web APIs. This guide explains resources, the REST API, profiles, extensions and versions in plain terms.
"HL7 or FHIR?" is a confusing question because FHIR is an HL7 standard. This guide separates the organization from its family of standards and explains where each fits.
A side-by-side technical look at HL7 v2 messaging and FHIR: data structure, transport, eventing, mapping an ADT^A01 to FHIR, and how the two coexist in real architectures.
A practical walk-through of integrating with a FHIR REST API, from reading the CapabilityStatement to authentication, searching, paging, error handling, rate limits and testing.
A step-by-step plan for implementing FHIR, from discovery and implementation guide selection through mapping, terminology, testing, go-live and ongoing operations, plus the challenges that derail projects.
FHIR integration budgets vary widely. This guide breaks down the factors that drive cost, compares build, buy and partner options, and gives illustrative planning ranges.
FAQ
Questions about finding a FHIR vendor
How the directory works, and what to know before you start evaluating FHIR vendors.
Read our methodologyA FHIR vendor is any company whose product or service helps organizations exchange health data using HL7 FHIR. That includes FHIR server and data platforms, integration engines and API networks, managed cloud FHIR services, and consultancies that design and build FHIR solutions. Our directory groups them by type so you can compare like with like.
No. Taction Software, which is affiliated with the owner of this site, is shown first and labelled; all other listings are alphabetical. "Featured" is an editorial choice to show the range of vendor types, not a ranking. Sponsored placements are always labelled and shown separately. See our editorial policy.
Each profile is compiled from the vendor's own public materials and lists the source URLs used. Capabilities are marked as vendor-stated unless a profile is labelled "Editorially reviewed". Always confirm details such as FHIR version support directly with the vendor.
For most production work in the US today that means FHIR R4 with the US Core implementation guide, plus SMART App Launch for authorization. R5 matters for some newer features. Our R4 vs R5 guide explains the trade-offs.
It depends on scope: the number of EHRs, read versus write access, implementation guide conformance, terminology mapping and ongoing maintenance. Our FHIR integration cost guide breaks down the drivers so you can compare quotes.
