How to connect to the Barentswatch API.
The BarentsWatch API supports Open ID Connect flows (client credentials, authorization code, and device code). You will need to register a client with us in order to access the APIs. The OpenID discovery document is here: https://id.barentswatch.no/.well-known/openid-configuration
Registering a Client
In order to access the Barentswatch API you need an Api Client. You can register your own client API Client connected to your user. To to so you must first create a user and log in at https://www.barentswatch.no/minside/. Here you can self register clients for use with your application.
Self registered clients only supports Open ID Connect's client_credentials flow. You If you need to use something other than credentials flow, you will have to contact BarentsWatch (firstname.lastname@example.org) to set up other types of clients.
The OpenID discovery document is here: https://id.barentswatch.no/.well-known/openid-configuration (production).
How to request an access token
Obtaining an Access Token
Once you have a client (either from self-registration on MyPage/Minside, or obtained from BarentsWatch.
) you can use the clients ClientID and ClientSecret to obtain an Access Token. The Access Token is used for granting access to endpoints providing data.
An application can obtain a token for use with the BarentsWatch API by posting a token request via HTTPS to https://id.barentswatch.no/connect/token:
- Use HTTPS POST
- URL must be id.barentswatch.no/connect/token
- Header 'content-type' must be 'application/x-www-form-urlencoded'
- Body must have four key-value pairs, separated by ampersand (&):
- Key 'grant_type' must have value 'client_credentials'
- Key 'client_id' must have your full client ID as value, which is often written like this: email@example.com:myclient. If your client does not url-encode automatically, you must url-encode it like this: myusername%40example.com%3Amyclient
- Key 'client_secret' must have a client secret you have created, as value.
- Key 'scope' must have value 'api'
Note that the client_id, client_secret, scope (and grant_type) need to be sent in the body – not as headers!
