Can you list the main characteristics of different HTTP methods?

Main HTTP methods and their characteristics:

• GET: Requests data from the server. Safe and idempotent method, should not change the server's state.
• POST: Sends data to the server to create a resource or perform an action. Not idempotent.
• PUT: Completely replaces the resource on the server. Idempotent.
• PATCH: Partially updates the resource. Not necessarily idempotent.
• DELETE: Deletes the resource. Idempotent.
• HEAD: Requests only the response headers, without the body.
• OPTIONS: Requests the methods supported by the server for the resource.

Understanding these methods is important for proper API testing and interaction with web services.
