Access Token Endpoint

The access token endpoint is an endpoint to obtain OpenID Connect Access Tokens and similar to the OpenID Provider's token endpoint. The access token endpoint can be used with a mytoken as the OIDC token endpoint can be sued with a refresh token.

Access Token Request

To obtain an OIDC access token the client makes an access token request to the access token endpoint by adding the following parameters using the application/json or application/x-www-form-urlencoded format in the HTTP request entity-body:

Parameter Necessity Description
oidc_issuer OPTIONAL The issuer url of the OpenID Provider
grant_type REQUIRED. MUST be mytoken or refresh_token
mytoken REQUIRED, unless refresh_token is given The mytoken that should be transferred
refresh_token REQUIRED if mytoken not given This is an alias for mytoken to be compatible with OIDC.
scope RECOMMENDED The scopes for the requested access token as a space separated list; if omitted all scopes allowed by the used mytoken are used (if multiple restriction clauses can be used, the first match is used)
audience OPTIONAL The audiences for the requested access token as a space separated list; if omitted all audiences allowed by the used mytoken are used (if multiple restriction clauses can be used, the first match is used)
comment OPTIONAL A comment string indicating the intended usage of the access token

Example

POST /api/v0/token/access HTTP/1.1
Host: mytoken.example.com
Content-Type: application/json

{
    "oidc_issuer": "https://op.example.org",
    "grant_type": "mytoken",
    "mytoken": "eyJhbGcio...",
    "scope": "openid profile eduperson_entitlement"
}

Access Token Response

A successful response is analog to a successful access token response from the authorization server as described in OAuth 2 Section 5.1. In particular the response returns the following parameters (if possible) using the application/json media type:

Parameter Necessity Description
access_token REQUIRED The access token issued by the authorization server
token_type REQUIRED The type of the token issued as described in OAuth 2 Section 7.1
expires_in RECOMMENDED The lifetime in seconds of the access token
scope OPTIONAL The scope of the access token
audience OPTIONAL JSON array indicating the audiences of the access token

Example

HTTP/1.1 200 OK
Content-Type: application/json

{
    "access_token":"2YotnFZFEjr1zCsicMWpAA",
    "token_type":"Bearer",
    "expires_in":3600,
    "scope": "openid profile"
}
