Is it possible to send payload in webhook

On button(payload) click in chat-bot widget, we are sending request to webhook(REST) in below mentioned format.

{ “sender”: “1”, “message”: “action_help” }

When we using payload we already knew the intent(for me it is “action_help”). In this case if have an option to mention the intent / payload in webhook it will be helpful.

At times I am also getting different intent for the payload options.
