Can you list the main HTTP methods you know?

Main HTTP methods:

• GET — request to retrieve data from the server.
• POST — send data to the server to create a resource.
• PUT — update an existing resource or create it if it does not exist.
• DELETE — delete a resource.
• PATCH — partial update of a resource.
• HEAD — retrieve only response headers without the body.

These methods are used for client-server interaction in web applications and APIs.
