4. Request and Response

Dive into the structure of API requests and responses. Learn how to format request payloads and handle different response formats (e.g., JSON, XML). Understand how to provide appropriate headers, including content type and accept headers.

Request: A typical API request consists of an HTTP method, headers (including content type), a URI, and an optional request body containing data.

Response: An API response includes an HTTP status code, headers, and a response body containing the requested data or an error message. Common response formats include JSON and XML.
