Authentication
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. The SDKs apply Digest authentication whenever they make a request to a Telesign service where it is supported. When Digest authentication is not supported, the SDKs apply Basic authentication.
