Fetching a SMART on FHIR enabled HealthLake data store's Discovery Document

For a client application to make a successful FHIR REST request, it needs to gather the authorization requirements defined in the HealthLake data store. No authorization (bearer token) is required for this request to succeed.

To do so, make a GET request and append /.well-known/smart-configuration to the endpoint of the data store

GET https://healthlake.your-region.amazonaws.com/datastore/your-datastore-id/r4/.well-known/smart-configuration

This returns the HealthLake data store's Discovery Document as a JSON blob. In it, you will find the authorization_endpoint and the token_endpoint along with the specifications and capabilities defined in the HealthLake data store.

{
  "authorization_endpoint": "https://oidc.example.com/authorize",
  "token_endpoint": "https://oidc.example.com/oauth/token",
  "capabilities": [
    "launch-ehr",
    "client-public"
  ]
