title: how to send a request to google home\assistant like IFTTT+webhooks
body: <p>Please direct me the right way. I'm stuck with some documentation issue. Going to code a small service with Google HOME for everyone to add a new phrase and make a POST request or answer with specific "TEXT" (like IFTTT run with WEBHOOKS) (fe: "Hey Google switch my kitchen light" -> service will send POST request to my own HTTP server). I know that IFTTT works but - I would to code the target service for tiny cases with fast response.</p>
  
  <p>I tried to understand all Google Assistant layers - but still no luck and didn't find the clear path.</p>
  
  <p>What I learned are: 
  1. connect to Google Account using OAuth 2 
  2. .... save the phrase and action for that in my DB - it's ok and simple way 
  3. ...??? how to send and to where? in (json?) a specific format 
  4. receive the answer from google home to understand the right case and make my action.... (for example: turn on\off the kitchen light)</p>
  
  <p>It should be not so hard as I can image.... anyway Please help :). </p>
  
  <p>Appreciate your time and answers and have a nice day!</p>
