## Resource Profile: NL Generic Functions Endpoint Profile ( Experimental )

Official URL: http://nuts-foundation.github.io/nl-generic-functions-ig/StructureDefinition/nl-gf-endpoint | Version: 0.2.0
Draft as of 2025-10-15 | Computable Name: NlGfEndpoint

The technical details of an endpoint that can be used for electronic services, such as for web services providing access to FHIR resources.

Usages:

- Examples for this Profile: FHIR STU3 Endpoint, FHIR Endpoint 2, FHIR Endpoint 3, FHIR Endpoint 1... Show 5 more, FHIR STU3 Endpoint, FHIR R4 Endpoint, FHIR Endpoint 2, DICOM-WADO-RS Endpoint and FHIR Endpoint 1
- CapabilityStatements using this Profile: Administration Directory for Administration Client, Administration Directory for Update Client and Query Directory for Query Client

You can also check for usages in the FHIR IG Statistics
