| Official URL: http://fhir.org/argonaut/smart-imaging/StructureDefinition/requires-access-token | Version: 0.1.0 | |||
| Draft as of 2026-08-21 | Computable Name: RequiresAccessToken | |||
Indicates whether retrieving data from this endpoint requires the same access token that authorized the request which returned the endpoint.
When true on a WADO-RS Endpoint returned by a SMART Imaging Access server,
the app presents the same SMART access token it used for the ImagingStudy
search when it retrieves DICOM data from the endpoint.
This mirrors the requiresAccessToken concept from the
FHIR Asynchronous Bulk Data Request Pattern,
expressed as an extension so it can travel on an Endpoint resource.
Context of Use
This extension may be used on the following element(s)
