It is a common practice that APIs should accept JSON requests as the payload and also send responses back. JSON is a open and standardized format for data transfer. It is derived from JavaScript in a way to encode and decode JSON via the Fetch API or another HTTP client.

What is the best way to secure Web API?

For security concerns, it is recommended that the Web APIs should use the HTTPS (HTTP secure) endpoints to ensure that the data communication is encrypted using TLS/SSL (Transport Layer Security). By the way, SSL is a cryptographic protocol responsible for ensuring secure communication over a computer network.
