FHIR R4 is typically used for:

Point-of-care data access
Patient-centric clinical data retrieval
Integration with modern FHIR-native systems

All resources follow the HL7 FHIR R4 specification, with Health Gorilla–specific extensions where applicable. The API Reference lists the supported operations per resource.

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

Base URLs

FHIR R4 endpoints are accessed using a common base URL per environment. Resource paths are appended to the base URL (for example, /Patient, /Observation).

Environment	Base URL
Sandbox	`https://sandbox.healthgorilla.com/fhir/R4`
Production	`https://api.healthgorilla.com/fhir/R4`

FHIR R4 Resource Capabilities

The table below summarizes the operations documented for FHIR R4 resources in the Health Gorilla API Reference and highlights the Health Gorilla solutions where each resource is commonly surfaced in client-facing workflows.

Associated solutions are illustrative and non-exhaustive. Resource availability and behavior depend on enabled products, configuration, and granted scopes.

† The Download PDF column applies to resource-level document retrieval and does not apply to patient-scoped export or aggregation operations.

Notes

Operation support varies by resource. Use the API Reference operations listed under each resource as the source of truth.
“Download PDF” is a resource-specific GET operation where documented (for example, DiagnosticReport, DocumentReference, RequestGroup, and ServiceRequest).
Patient-level aggregation using the FHIR standard is documented under Patient/$everything (GET).
