SMSing from Keap using Twilio

Hey, I’m trying to have keap sms clients as well as emailing them. I’ve set up a twilio account a and applied instructions as directed.

Yet it’s still not working. Has anyone don this know what I’m missing?

I’ve attached the screenshots of the settings I’m using.




I’m an integrations developer and I’ve never seen any of the SMS systems (Twilio, message bird etc) just take post parameters. Usually it has to be sent via JSON body. This can’t be done through campaign builder’s http post widget but can be done with some code that the http post sends to so that it can then be formatted for the api of the sms product. It’s possible zapier may have a solution that basically does the same thing though?
