The webhook ir rather simple. Takes the info from VAPI to an Excel or to Twilio, so as to send an SMS to this number.
I can get it right into the excel. Twilio does not accept it.
I tried also typing +1 in Twilio field, before connect the data from the webook - since in my twilio trial account this number is whitelisted with +1 format.
I have defined the variable as string in VAPI, showing as Text in Make.
If I type the phone number manually in Twilio module, it works, but of course I want that this number is being read from the webhook.
