        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)

        ```

```
