How to get identities access_token inside an Action

Get Help
1

This page https://auth0.com/docs/authenticate/database-connections/custom-db/custom-database-connections-scripts/execution#identity-provider-tokens suggests that if I return an access_token and refresh_token in login custom script, the user profile will contains the linked identity.

I can’t find how I can retreive that information inside an Custom post-login action.
event.user.identities only contains basic connection fields:

{ connection: 'custom-backend', isSocial: false, provider: 'auth0', userId: 'custom|2000000|4', user_id: 'custom|2000000|4' }

I manage to get it using the management API. But it seems overkill.
Even the test sample in action contains an access token :thinking::

"user": {
    "app_metadata": {},
    "created_at": "2022-10-18T15:29:04.063Z",
    "email_verified": true,
    "email": "j+smith@example.com",
    "family_name": "Smith",
    "given_name": "John",
    "identities": [
      {
        "connection": "Username-Password-Authentication",
        "isSocial": false,
        "provider": "auth0",
        "userId": "5f7c8ec7c33c6c004bbafe82",
        "accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gU21pdGgiLCJpYXQiOjE1MTYyMzkwMjJ9.Q_w2AVguPRU2KskCXwR7ZHl09TQXEntfEA8Jj2_Jyew",
        "profileData": {},
        "user_id": "5f7c8ec7c33c6c004bbafe82"
      }

How did you actually get the access token of the user in an action? I am running into the same issue, and the code I’m using with the management API isn’t working.

Here it is.

try {
    const auth0Domain = 'MY AUTH0 DOMAIN';
    const auth0ManagementApiClientId = event.secrets.CLIENT_ID
    const auth0ManagementApiClientSecret = event.secrets.CLIENT_SECRET
    const userId = event.user.user_id;

    const response = await axios.post(
      `https://${auth0Domain}/oauth/token`,
      {
        grant_type: 'client_credentials',
        client_id: auth0ManagementApiClientId,
        client_secret: auth0ManagementApiClientSecret,
        audience: `https://${auth0Domain}/api/v2/`,
        scope: 'read:users',
        subject: userId,
      }
    );

    const accessToken = response.data.access_token;

    await axios.post('MY API URL', {
    }, {
      headers: {
        Authorization: `Bearer ${accessToken}`,
      },
    })

    console.log('Successfully called the API');

  } catch (error) {
    // Handle error response
    console.error('Error retrieving access token:', error);
  }

This code is succesful in getting A access token, but it’s not the same as the users, which I’ve verified by manually printing out the access token from this request and a valid request on the backend. So whos accces token is it, I don’t know??

Any help?

I only wanted to get the delegated access_token. You cannot access the actual auth0 token.
