What HTTP methods do you know?

Main HTTP methods:

• GET — request to retrieve a resource without changing the server's state.
• POST — sending data to the server, often to create new resources.
• PUT — replacing or creating a resource at the specified URI.
• DELETE — deleting a resource.
• PATCH — partial update of a resource.
• HEAD — request for resource headers without the body.
• OPTIONS — request for supported server methods for a resource.
• TRACE — diagnostics of the request route.

Each method has its purpose and semantics, which is important to consider when designing APIs and testing.
