When an API client makes an HTTP request with an Accept header containing the value "application/json", the API server should respond with a payload formatted as JSON. Here’s a detailed explanation:

Accept Header:

Purpose: The Accept header indicates the media type(s) that the client is willing to receive from the server.

Value "application/json": Specifies that the client expects a response in JSON format.

Valid JSON Response:

Format: JSON (JavaScript Object Notation) is a lightweight data interchange format that uses key-value pairs.

Example: A valid JSON response for the requested format would be {"status": "healthy"}.

Key: "status"

Value: "healthy"
