I've been using actions on Google Assistant by Dialogflow to creat my own assistant, the Dialogflow's webhook uses a POST command unlike the GET command of Join, so I used Zapier to receive the POST and do a GET webhook using the Dialogflow parameters in the Join's URL. This is working fine and I can send a lot of commands, but I cant get responses. I want to do a PHP program to use as my own webhook, to send pushes to Join and receive responses. The only thing that is stopping me is that I don't know anything about PHP, so if someone could help me to do it, I would be very gratefull. There is one thing im thinking right now: I'd need a new especific Join device to do that and get the responses?
