Use case for getting the GP Connect FHIR server's capability statement

Prerequisites

Consumer

The consumer system:

API usage

Request operation

FHIR relative request

GET /metadata

FHIR absolute request

GET https://[proxy_server]/https://[provider_server]/[fhir_base]/metadata

Request headers

Consumers SHALL include the following additional HTTP request headers:

Header Value
Ssp-TraceID Consumer’s TraceID (i.e. GUID/UUID)
Ssp-From Consumer’s ASID
Ssp-To Provider’s ASID
Ssp-InteractionID urn:nhs:names:services:gpconnect:fhir:rest:read:metadata-1

Payload request body

N/A

Error handling

Provider systems are expected to always be able to return a valid capability statement.

Request response

Response Headers

Provider systems are not expected to add any specific headers beyond that described in the HTTP and FHIR® standards.

Payload response body

Provider systems:

  • SHALL return a 200 OK HTTP status code on successful retrieval of the capability statement
  • SHALL return a capability statement which conforms to the standard FHIR CapabilityStatement

An example GP Connect CapabilityStatement is shown below ready for customisation and embedding into GP Connect assured provider systems. Providers should use this CapabilityStatement as a base for their own CapabilityStatement, replacing the element in square brackets ([ & ]) with specific information of their implementation. The main version at the top of the CapabilityStatement should represent the GP Connect specification version which the FHIR server implements.

Consumer systems:

  • SHOULD request the capability statement from the FHIR server endpoint in order to ascertain details of the implementation of GP Connect capabilities delivered by the FHIR server
  • Consumers may also cache the capability statement information retrieved from an endpoint to reduce the number of future calls they make to the target organization’s FHIR server.

Examples

C#

var client = new FhirClient("http://gpconnect.aprovider.nhs.net/GP001/STU3/1/");
client.PreferredFormat = ResourceFormat.Json;
var resource = client.CapabilityStatement();
FhirSerializer.SerializeResourceToXml(resource).Dump();
