The Hypertext Transfer Protocol Secure (HTTPS) is the secure version of HTTP that encrypts communication between clients and servers using Transport Layer Security (TLS), ensuring data confidentiality, integrity, and authentication during transmission.

A fundamental message exchange pattern where a client sends a request and a server returns a corresponding response.

A machine-readable specification for describing HTTP APIs, enabling AI systems and applications to discover and integrate callable API operations.

An HTTP callback mechanism that sends real-time data payloads to target applications when specific events occur.
