How to read full input json in custom action

I want to greet user with the name. For this my application will post the below json to rasa with username in “sender” option.

response =“http://localhost:5005/webhooks/rest/webhook”, headers = { “Content-Type”: “application/json” }, json = { ‘message’: ‘hi’ , “sender”: “aniket”} )

How do i use custom action for this. My file is

class UserName(Action): def name(self): return “utter_greet_user”

def run(self, dispatcher, tracker, domain):

	return []

If i could read “sender” option from input json in my action file then i can call this action while greeting. Any suggestions?

Hi Aniket, you can use tracker.sender_id to get the “sender” from the json send to actions server.
