If you use a Telesign SDK to make your request, authentication is handled behind-the-scenes for you. All you need to provide is your Customer ID and API Key(or password). The SDKs apply Digest authentication whenever they make a request to a Telesign service where it is supported. Intelligence uses Basic authentication.
