Why is HTTPS required for modern APIs and PWAs?

Example Concept: HTTPS uses TLS (Transport Layer Security) to encrypt data transmitted between the client and server, preventing eavesdropping and man-in-the-middle attacks. This security measure is mandatory for PWAs to access certain features like service workers and push notifications, as browsers require a secure context to enable these capabilities. Similarly, APIs that handle sensitive data must use HTTPS to protect user information and ensure data integrity during transmission.
