The ticket obtained by authentication_session_ticket_for_webapi is authenticated using ISteamUserAuth/AuthenticateUserTicket and returns invalid ticket.

{
  "response": {
    "error": {
      "errorcode": 101,
      "errordesc": "Invalid ticket"
    }
  }
}

Does anyone have any experience with this, please?
