Twilio Conversations, you must first verify the phone number you plan to use for outbound messaging. This verification step is mandatory only for Twilio trial accounts. Twilio Conversations also supports several other messaging channels, including in-app messaging, Facebook Messenger that you can configure for your use case.

2. Obtaining the Account SID and Auth Token for your project.

2. Creating the UI in DronaHQ
a. Create a blank application, and add two text input controls for the user name and email. Add a phone control for the phone number to which we want to send the messages to. Also, add rating and text area control for rating and feedback description respectively. At the end add a button, on whose “button_click” action we will configure the Twilio send SMS event.

Firstly add a Validate Screen action, which will check for all the validations and mandatory fields have been filled or not.

-Then bind the “Message Text” with the “message” action we created, “Recipient’s Number” with the concatenated phone number from the action flow, and at the end add the “Sender’s Number” from Twilio.
