EMR Direct phiQuery FHIR integration API
Overview
The EMR Direct phiQuery FHIR integration API is a component of EMR Direct’s Interoperability Engine, designed to facilitate health information exchange using the HL7 FHIR standard. It enables health data holders to make FHIR resources available to authorized users and client applications.
- What it does: The phiQuery API allows for the secure exchange of health data over the internet, supporting read-only RESTful HL7 FHIR R4 API requests and FHIR Bulk Data Access Group export. It also includes support for OAuth and OpenID Connect for authentication and authorization.
- Who it is for: This tool is primarily for health IT developers and organizations that manage patient data, such as hospitals, clinics, and other healthcare providers, who need to enable modern API-based interoperability. It assists in meeting ONC Health IT certification criteria for application access and standardized APIs for patient and population services.
- How it fits a clinical or practice workflow: The phiQuery API integrates with existing EMR software, allowing authorized third-party applications or patient portals to access patient health data. This can support clinical decision-making, care coordination, and patient engagement by enabling applications that help patients access their own health information.
- Notable capabilities: The API supports USCDI v3 and SMART v2, and is designed to meet 2026 ONC certification requirements, including g.7, g.9, and g.10 criteria. It also offers an integration model where data remains on the implementer’s system and is returned to authorized requesters in real-time. EMR Direct provides developer tools, including SDKs, sandbox environments, and testing guides, to aid in integration and certification.

Overall: MixedStrengths
- Easy integration with lightweight SDKs and connectors for multiple programming languages (Java, .NET, Python, PHP, Node.js, Ruby).
- Helps meet ONC certification criteria for Application Access (g.7, g.9) and Standardized API for patient and population services (g.10).
- Supports secure exchange of protected health information with built-in support for SMART, UDAP, and OAuth.
- Provides a complimentary developer account with sandbox environments, sample code, documentation, and technical support for testing and certification.
- Allows data to remain on the implementer's system, with real-time data return to authorized requesters.
- Offers an API management platform and resources for client app developers through the HealthToGo App Studio.
Limitations
- Limited public reviews from physicians, healthcare IT professionals, or on platforms like Reddit, G2, or Capterra, making it difficult to gauge widespread user experience.
- While FHIR is a standard, individual institutions may implement it differently, potentially leading to integration challenges with specific EHRs like Epic.
- Integrating with major EHR systems like Epic can involve lengthy approval processes and potential fees for production access.
