Token exchange issue

Questions OAuth/OIDC

Hello. Im trying to exchange access token using the following guide: Set up OAuth 2.0 On-Behalf-Of Token Exchange

But it fails with error: {"error":"invalid_request","error_description":"The required parameter 'actor_token' is missing."} Am I missing something? This guide doesn’t say anything about actor_token…

Hello,

  • Include the actor_token in your token exchange request. This should be the access token of the client application making the request on behalf of the user.

  • Ensure your request includes both the actor_token and subject_token parameters. The subject_token should be the user’s access token that you’re trying to exchange.

  • Your request should look something like this:

    curl --request POST \
      --url https://{yourOktaDomain}/oauth2/default/v1/token \
      --header 'Accept: application/json' \
      --header 'Content-Type: application/x-www-form-urlencoded' \
      --data-urlencode 'client_id={client 2 ID}' \
      --data-urlencode 'grant_type=urn:ietf:params:oauth:grant-type:token-exchange' \
      --data-urlencode 'actor_token={deviceSecret}' \
      --data-urlencode 'actor_token_type=urn:x-oath:params:oauth:token-type:device-secret' \
      --data-urlencode 'subject_token={idToken}' \
      --data-urlencode 'subject_token_type=urn:ietf:params:oauth:token-type:id_token' \
      --data-urlencode 'scope=openid offline_access' \
      --data-urlencode 'audience={audience}'
