Connect n8n to checkpoint harmony endpoint

Questions

  1. I generated an API Key from the Infinity Portal, assigned to the Endpoint service, with the Admin role.

  2. I successfully obtain a token from:

    https://cloudinfra-gw-us.portal.checkpoint.com/v2/auth/external

    The response returns "success": true and a valid token.

  3. I use that token in the request header:

    Authorization: Bearer <token>
Content-Type: application/json

  4. Then I try to query endpoints using:

    POST https://cloudinfra-gw-us.portal.checkpoint.com/app/harmony-endpoint-web/api/v1/endpoint/query

    (I also tried /app/hec-api/v1/agents/query).

Result:

The server responds with:

403 Forbidden – perhaps check your credentials

or sometimes:

Authentication required

The token is active and valid (verified by decoding the JWT), so it doesn’t seem to be an authentication issue (401), but rather an authorization problem.
