GraphQL FHIR resources S-Z

This page records root fields found by introspecting the Ovok sandbox on 8 October 2026. Every listed type links to its canonical FHIR R4 resource page, which remains the source for resource elements, parameter meanings, and REST interactions. See queries and pagination for common arguments and their behavior, and mutations for shared write signatures.

The search column lists only resource-specific arguments. The schema declares these as GraphQL String arguments. A field in this snapshot is not a guarantee that every environment or AccessPolicy permits the operation.
