About FHIR R4

Health Gorilla’s FHIR R4 implementation supports real-time access to structured clinical data across a wide range of FHIR resources. This version is ideal for use cases involving:

  • Point-of-care data access
  • Real-time patient queries
  • Integration with modern FHIR-native systems

FHIR R4 is used in synchronous APIs, including resource-level access (GET /fhir/R4/AllergyIntolerance) and system-wide interactions. All resources follow the HL7® FHIR® R4 specification, with Health Gorilla–specific extensions where applicable.

Tip: If your calls begin with /fhir/R4/..., you're using the R4 version of the API.
