Creé la aplicación web rails. Cuando el usuario realiza algunas acciones, mi aplicación debe crear un nuevo evento en mi Google Calendar. Para mi tarea, elijo la autorización de servidor a servidor.

Escribí el siguiente código ruby:

  client = Google::APIClient.new({:application_name => "Rails calendar",
                         :application_version => "1.0"})

  keypath = Rails.root.join('config','google_secrets.p12').to_s
  key = Google::APIClient::PKCS12.load_key(keypath, "notasecret")

# generate request body for authorization
  client.authorization = Signet::OAuth2::Client.new(
      :token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
      :audience             => 'https://accounts.google.com/o/oauth2/token',
      :scope                => 'https://www.googleapis.com/auth/calendar',
      :issuer               => '***',
      :signing_key          => key).tap{ |auth| auth.fetch_access_token! }


  api_method = client.discovered_api('calendar','v3').events.insert
  @meeting_data = {
      guests: [{email: '***@gmail.com'}, {email: '***@gmail.com'}],
      start_time: "2016-08-10T19:00:00+03:00",
      end_time: "2016-08-10T20:00:00+03:00",
      topic: "Test meeting",
      messages_thread_id: 2
  }

  event = {
      summary: @meeting_data[:topic],
      start: {
          dateTime: @meeting_data[:start_time],
          time_zone: 'Asia/Jerusalem'
      },
      end: {
          dateTime: @meeting_data[:end_time],
          time_zone: 'Asia/Jerusalem'
      },
      attendees: @meeting_data[:guests],
      visibility: 'private',
      reminders: {
          useDefault: true,
      }
  }

  result = client.execute(:api_method => api_method,
                          :parameters => {calendarId: 'primary'},
                          :body => JSON.dump(event),
                          :headers => {'Content-Type' => 'application/json'})

  puts result.data.as_json

Pero cuando trato de usar ese código y el servidor me devuelve el resultado como JSON, si voy a la URL del evento "creado", google me muestra un mensaje de que el evento no existe.
