HumanUser in Json payload

Good morning to all. As I just have started to working with Shotgrid and its webhook beta options to integrate with our communicator. So the basic idea is to send the notification from Shotgrid with a webhook tool, but the problem is that, every notification has a “HumanUser” name in json template (regardlss the user name). Is there any solution to send the real name of user that is changing the state of shot with a webhook?
