Authorize is a standard endpoint that triggers authentication of an enduser via one of the IDP options, followed by authorization in terms of consent handling. Authorization information is then returned in the reponse to the requesting OIDC Client. The content of the authorization response is different for each of the supported message flows. The Authorize endpoint does in any case trigger a series of re-directs, eventually returning to the requesting OIDC Client at a redirect_uri specified by the client. For security reasons only pre-registered redirect URIs are allowed.

| Name | Description |
|---|---|
scope | List of scope values specifying what kind of resources (dataset) the OIDC Client requests access to. The value openid must always be included in the list. Note that scope values are case-sensitive. |
response_type | Determines the message flow to be used, thus also governing the content and type of the response from the Authorize endpoint. The following combinations are supported:
|
client_id | Unique ID (arbitrary string) for the OIDC Client in question. This is created as part of the provisioning process. |
redirect_uri | Redirect URI to which the Authorize response will be sent. This URI must exactly match one of the Redirect URI values for the OIDC Client pre-registered at the OpenID Provider |
state | Opaque value used to maintain state between the request and the callback. |
response_mode | The response mode to be used for returning parameters from the Authorization Endpoint. The following values are supported:
|
nonce | String value used to associate a ODIC Client session with an ID Token, and to mitigate replay attacks. The value is passed through unmodified from the Authentication Request to the ID Token |
ui_locales | May be used to set a language preference for GUI handling. The default GUI experience supports 'nb' (Norsk Bokmål) and 'en' (English). If ui_locales is not set, the first (if any) Accept-Language header of the request is used to dermine preferred locale. Otherwise 'nb' is used by default. |
prompt | Support for the standardized values none and login. The former can be used to check for an existing (still valid) authentication session with the OIDC provider. The latter can be used to force a re-authentication, possibly with a different login_hint and/or acr_values. |
acr_values | Requests use of any IDP at a given Level of Assurance (Authentication Context Class Reference) or above. A selector dialogue is shown to the enduser if more than one IDP option meet the required minimum level. Note that this parameter has no effect if the |
login_hint | This parameter may be used to specify the use of any particularly named IDP (Authentication Method Reference) along with any pre-configuration for the designated IDP. Note that this parameter has no effect f the See further details on login_hint support for each of the supported IDPs. |
id_token_hint | JWT value for an ID Token previously issued by the OIDC Provider used as a hint about the enduser's authenticated session with the OIDC provider. Note that this parameter has precedence before both acr_values and login_hint, but precedence after the prompt parameter. If the ID Token has expired, a new authentication is triggered for the IDP option that was used when the ID Token was issued. Otherwise the authentication is still granted valid and the OIDC Provider proceeds directly to consent handling. |
