Most resources in Health Gorilla's FHIR API are tied to a specific patient. This page provides a reference guide to all supported resource types that reference or depend on the Patient resource, grouped by their clinical or operational function.

This overview is useful for developers building patient-centric applications or workflows, especially when using queries like:

GET /[ResourceType]?patient=Patient/{id}

or

GET /Patient/{id}/$everything
