Method: fhir.history

Full name: projects.locations.datasets.fhirStores.fhir.history

Lists all the versions of a resource (including the current version and deleted versions) from the FHIR store.

Implements the per-resource form of the FHIR standard history interaction (DSTU2, STU3, R4).

On success, the response body contains a JSON-encoded representation of a Bundle resource of type history, containing the version history sorted from most recent to oldest versions. Errors generated by the FHIR store contain a JSON-encoded OperationOutcome resource describing the reason for the error. If the request cannot be mapped to a valid API method on a FHIR store, a generic GCP error might be returned instead.

For samples that show how to call history, see Listing FHIR resource versions.
