Vonage Video API - Secure Callbacks Public Beta Announcement

The Vonage Video API has introduced a new feature called Secure Callbacks, which is currently available in public beta and will be made generally available in June 2023. This feature provides an additional layer of security to protect against unauthorized callbacks and ensures compliance with specific industries' requirements. Developers can enable this feature by toggling the Secured Callback slider button on in their project settings, and then configure the callback URL and signature secret to verify the authenticity and payload integrity of incoming requests. Secure Callbacks includes a JWT in the Authorization header, which corresponds to the user-configured signature secret, and also allows developers to verify the request payload has not been tampered with during transit by comparing an SHA-256 hash of the payload to the `payload_hash` field found in the JWT claims.
