Obtaining A Session
Prior to connecting to any API, your administrator should setup an Application identity and a Device identity (if not using two-way TLS).

Application / Client Session

A client-credentials session is used whenever your application will be interacting with the SanteDB system without user interaction. This is primarily intended for back-end processes, system integrations, etc.
To request a client-credentials session you will need:
  • Your client_id and your client_secret provided by your system administrator
  • Either:
    • A client certificate which is used to authenticate the node you're using, or
    • A device_id and a device_secret provided by your system administrator.
To authenticate, first, take your device credentials and encode them as a base64 payload, for example if you device id is EXAMPLE_DEVICE_NODE and the secret is qlcEtboF-H5XdK4x1t-arL5GaG4svF9TkL5a , your device authentication header would be : RVhBTVBMRV9ERVZJQ0VfTk9ERTpxbGNFdGJvRi1INVhkSzR4MXQtYXJMNUdhRzRzdkY5VGtMNWE=
Next, locate your application credentials. These are generated by your system administrator, this example will use client_id of EXAMPLE_APPLICATION with secret 4toXrw0x-SpM1K4c7D$M0OkJcA1OgW4HeOlV
Next, construct an HTTP POST request to the endpoint <root>/auth/oauth2_token , setting the X-Device-Authorization header and the appropriate OAUTH payload:
POST http://mpi-test.local:8080/auth/oauth2_token HTTP/1.1
User-Agent: Fiddler
Content-Type: application/x-www-form-urlencoded
Host: mpi-test.local:8080
Content-Length: 118
The server will respond with a series of tokens:
HTTP/1.1 200 OK
Content-Length: 1307
Content-Type: application/json
Server: Microsoft-HTTPAPI/2.0
Date: Mon, 11 Jan 2021 17:16:03 GMT
Your application should store the access_token somewhere in memory as this will need to be attached to all your requests.
You can decode the id_token to get key information about the session granted such as policies, permissions, expiration time, etc.

Using the Access_Token

The access_token is attached to each subsequent request as a BEARER token session
