GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS, TRACE.

Method	Description	Safe	Idempotent
GET	Request a resource.	Yes	Yes
POST	Send data for processing, often results in creating a new resource.	No	No
PUT	Update or create a resource at the specified URI.	No	Yes
DELETE	Delete a resource.	No	Yes
PATCH	Partially update a resource.	No	No
HEAD	Get only response headers, similar to GET.	Yes	Yes
OPTIONS	Get information about server or resource capabilities.	Yes	Yes
TRACE	Debugging, echo request to the server (rarely used for security reasons).	Yes	Yes

Safe means the request does not change the server state. Idempotent means that executing the request multiple times will produce the same result as executing it once (regardless of the number of repetitions).
