Frontline REST API Overview
All URLs in the reference documentation use the following base URL:
https://frontline-api.twilio.com/v1
To authenticate requests to the Twilio APIs, Twilio supports HTTP Basic authentication. Use your API key as the username and your API key secret as the password. You can create an API key either in the Twilio Console or using the API.
Note: Twilio recommends using API keys for authentication in production apps. For local testing, you can use your Account SID as the username and your Auth token as the password. You can find your Account SID and Auth Token in the Twilio Console.
