SMART Backend services

This specification is designed to work with FHIR Bulk Data Access, but is not restricted to use for retrieving bulk data; it may be used to connect to any FHIR API endpoint.

Register a Client

Before a SMART client can run against a FHIR server, the client SHALL generate or obtain an asymmetric key pair and register its public key set as jsks_uri in Client resource. Aidbox provides .well-known/jwks.json endpoint so you can use it.

PUT /Client/inferno-my-clinic-bulk-client
content-type: application/json
accept: application/json

{
  "type": "bulk-api-client",
  "active": true,
  "auth": {
    "client_credentials": {
      "client_assertion_types": [
        "urn:ietf:params:oauth:client-assertion-type:jwt-bearer"
      ],
      "access_token_expiration": 300,
      "token_format": "jwt"
    }
  },
  "scope": [
    "system/*.read"
  ],
  "jwks_uri": "<AIDBOX_BASE_URL>/.well-known/jwks.json",
  "grant_types": [
    "client_credentials"
  ]
}

// 201 OK 

{
 "type": "bulk-api-client",
 "grant_types": [
  "client_credentials"
 ],
 "resourceType": "Client",
 "scope": [
  "system/*.read"
 ],
 "auth": {
  "client_credentials": {
   "client_assertion_types": [
    "urn:ietf:params:oauth:client-assertion-type:jwt-bearer"
   ],
   "access_token_expiration": 300,
   "token_format": "jwt"
  }
 },
 "active": true,
 "id": "",
 "jwks_uri": "https://releasetest.edge.aidbox.app/.well-known/jwks.json"
}

Create AccessPolicy for the Client

PUT /AccessPolicy/inferno-my-clinic-bulk-client 
accept: application/json 
content-type: application/json

{
  "engine": "allow",
  "link": [
    {
      "id": "inferno-my-clinic-bulk-client",
      "resourceType": "Client"
    }
  ]
}

{
 "id": "inferno-my-clinic-bulk-client",
 "link": [
  {
   "id": "inferno-my-clinic-bulk-client",
   "resourceType": "Client"
  }
 ],
 "engine": "allow",
 "resourceType": "AccessPolicy"
}

Obtain access token

To obtain an access token use /auth/tokenendpoint with following parameters:

Parametr

grant_type *

Fixed value - client_credentials

client_assertion_type *

Fixed value - urn:ietf:params:oauth:client-assertion-type:jwt-bearer

client_assertion *

Signed authentication JWT value.

*- required parameter

POST /auth/token
accept: application/json 
content-type: application/json
