I'm trying to connect to a Twilio studio flow using the Web service task to send a confirmation text message following registration in a Qualtrics survey. I have tried using an Action, as well as a Web Service in the survey flow. I have used the "Authorization" header, along with Basic and the Base64 encoded AccountSid:AuthToken. I've also tried using the SID and the Token strings Base64 encoding, but nothing seems to work. Has anyone had experience connecting to Twilio? Any help will be much appreciated.
Thanks,
Jose
