Hi everyone, I'm newbie in Nintex and I want to create a chatbot to help my automative job. E.g. I have a work flow to booking a meeting room, user will chat with bot to select the room and time, then bot will start the workflow to book a room and get approval from manager. Currently I try to test with Nintex Cloud, but I don't know how to set up the connection between chatbot and Nintex, are there any REST API to get information such as available room and time, how to start the workflow by REST API and how to integrate with my own exchange server. I think its basic but I can't find the anwser.
