<para>
Keycloak allows you to obtain an access token dedicated to some Client Application (not to any user).
See <ulink url="http://tools.ietf.org/html/rfc6749#section-4.4">Client Credentials Grant</ulink>
from OAuth 2.0 spec.
</para>
<para>
To use it you must have
registered a valid confidential Client and you need to check the switch <literal>Service Accounts Enabled</literal> in Keycloak
admin console for this client. In tab <literal>Service Account Roles</literal> you can configure the roles available to the service account retrieved on behalf of this client.
Don't forget that you need those roles to be available in Scopes of this client as well (unless you have <literal>Full Scope Allowed</literal> on).
As in normal login, roles from access token are intersection of scopes and the service account roles.
</para>
<para>
The REST URL to invoke on is <literal>/{keycloak-root}/realms/{realm-name}/protocol/openid-connect/token</literal>.
Invoking on this URL is a POST request and requires you to post the clientId and clientSecret of the client in <literal>Authorization: Basic</literal> header.
Later we want to add more mechanisms for authenticating clients. You also need to use parameter <literal>grant_type=client_credentials</literal> as per OAuth2 specification.
</para>
<para>
For example the POST invocation to retrieve service account can look like this:
<programlisting><![CDATA[
POST /auth/realms/demo/protocol/openid-connect/token
Authorization: Basic cHJvZHVjdC1zYS1jbGllbnQ6cGFzc3dvcmQ=
Content-Type: application/x-www-form-urlencoded
grant_type=client_credentials]]>
</programlisting>
The response would be this <ulink url="http://tools.ietf.org/html/rfc6749#section-4.4.3">standard JSON document</ulink> from the OAuth 2.0 specification.
<programlisting><![CDATA[
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
Cache-Control: no-store
Pragma: no-cache
{
"access_token":"2YotnFZFEjr1zCsicMWpAA",
"token_type":"bearer",
"expires_in":60,
"refresh_token":"tGzv3JOkF0XG5Qx2TlKWIA",
"refresh_expires_in":600,
"id_token":"tGzv3JOkF0XG5Qx2TlKWIA",
"not-before-policy":0,
"session-state":"234234-234234-234234"
}]]>
</programlisting>
</para>
<para>
The retrieved access token can be refreshed or logged out by out-of-bound request.
</para>
<para>
See the example application <literal>service-account</literal>
from the main Keycloak <literal>demo</literal> example.
