            SignalWire Basic Authentication using Project ID and API Token.


            The client sends HTTP requests with the Authorization header
            containing

            the word Basic followed by a space and a base64-encoded string of
            project_id:token.

            The project ID will be used as the username and the API token as the
            password.


            Example:

            ```

            Authorization: Basic base64(project_id:token)
