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:

Registering a Client

In order to access the Barentswatch BarentsWatch API you need an Api Client. You can register your own API Client connected to your user. To to so you must first create a user and log in at Here you can self register clients for use with your application.

When registering a client you need to choose between API-client and AIS-client, depending on the API you want to access. This also affects the 'scope' you must use when obtaining an access token.

Self registered clients only supports Open ID Connect's client_credentials flow. If you need to use something other than credentials flow, you will have to contact BarentsWatch ( to set up other types of clients.

  • 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: If your client does not url-encode automatically, you must url-encode it like this:
    • Key 'client_secret' must have a client secret you have created, as value.
    • Key 'scope' must have value 'api' or 'ais' depending on the type of API you want access

Note that the client_id, client_secret, scope (and grant_type) need to be sent in the body – not as headers!
