Trouble with webhooks

Here is the code for my webhook, I replaced all the pertinent information

{
  "eventName": "Twilio",
  "url": "https://api.twilio.com/2010-04-01/Accounts/account_SID/Messages",
  "requestType": "POST",
  "auth":
  {
    "username": "account SID",
    "password": "Auth token"
  },
"form": {
	"From" : "+18501111112",
	"To" : "+18501111111",
	"Body" : "Breakin Detected"
},
  "mydevices": true
}

I can go into my particle dashboard and watch when I pull the pin high, it responds and shows the whole process, but I never get a text. Any thoughts?

I just got three texts in a row, 11 hours later, is this delay normal for twilio?
