Before you start to use (or test) our RADAR API please:
Contact us for activating an OAuth ClientID. This client gives you permission to communicate with the RADAR backend authorization service.
In case you use RADAR with Shibboleth accounts: Please take note, that no Shibboleth account can be used for this API user, but only a user who has registered via the local RADAR database with ID / PW. Thus please create a new RADAR API user that is used to retrieve the OAuth token with its credentials.
