DISCLAIMER: This version of Frost
is still work in progress.
MET Norway does not guarantee that the service will always behave
100% according to documentation or expectations.
Authentication
Most users of Frost will only access open data through the API and as such will use basic authentication. This means that you use the user id and secret that you can create here in the request:
curl --user "client ID":"client secret" 'https://frost-beta.met.no/api/v1/obs/met.no/kvkafka/get?stationids=18700&elementids=air_temperature&time=latest'
Those that have special access to restricted data will need to use the OAuth 2 workflow. These users will need to be provided with a client id and secret and then use it to get tokens to send with each request:
curl --data "grant_type=client_credentials&client_id=X&client_secret=X" https://login.met.no/auth/realms/External/protocol/openid-connect/token
curl -H 'Authorization: Bearer TOKEN' 'https://frost-beta.met.no/api/v1/obs/met.no/kvkafka/get?stationids=18700&elementids=air_temperature&time=latest'
Those that want to use the OAuth 2 tokens that do not have special access will have to use a different endpoint to get a generic token:
curl --data "grant_type=client_credentials&client_id=X&client_secret=X" https://frost-beta.met.no/auth/token
