ClientCredentialsOAuth2ClientFilter

Authenticates OAuth 2.0 clients by using the client’s OAuth 2.0 credentials to obtain an access token from an Authorization Server, and injecting the access token into the inbound request as a Bearer Authorization header. The access token is valid for the configured scopes.

The ClientCredentialsOAuth2ClientFilter obtains the client’s access token by using the client_credentials grant type. Client authentication is provided by the endpointHandler property, which uses a client authentication filter, such as ClientSecretBasicAuthenticationFilter. The filter refreshes the access token as required.

Use the ClientCredentialsOAuth2ClientFilter in a service-to-service context, where services need to access resources protected by OAuth 2.0.

    "handler": "ForgeRockClientHandler",
    "filters": [
      {
        "type": "ClientSecretBasicAuthenticationFilter",
        "config": {
          "clientId": "myConfidentialClient",
          "clientSecretId": "my.client.secret.id",
          "secretsProvider" : "mySystemAndEnvSecretStore",
        }
      }
    ]
  }
}

Default: ForgeRockClientHandler

"clientId": configuration expression<string>, required
This property is deprecated. Use endpointHandler instead. For more information, refer to the Deprecated section of the Release Notes.

The ID of the OAuth 2.0 client registered with the Authorization Server.

If you use the deprecated properties, provide clientId, clientSecretId to obtain the client secret, which authenticates using the client_secret_basic method.

"clientSecretId": configuration expression<secret-id>, required
This property is deprecated. Use endpointHandler instead. For more information, refer to the Deprecated section of the Release Notes.

The ID to use when querying the secretsProvider for the client secret.

This secret ID must point to a GenericSecret.

"handler": Handler reference or inline Handler declaration, optional
This property is deprecated. Use endpointHandler instead. For more information, refer to the Deprecated section of the Release Notes.

The Handler to use to access the Authorization Server’s OAuth 2.0 token endpoint. Provide either the name of a handler object defined in the heap or specify a handler object inline.
