What do you know about REST? What request methods are available?

REST (Representational State Transfer) is an architectural style for creating web services based on the use of standard HTTP methods and stateless principles. In REST, resources are identified by URIs, and interaction with them occurs through standard HTTP methods.

Main HTTP methods in REST:

• GET — retrieve a resource or a list of resources.
• POST — create a new resource.
• PUT — complete update of a resource.
• PATCH — partial update of a resource.
• DELETE — delete a resource.
• OPTIONS — get supported methods for a resource.

REST assumes that the server does not store client state between requests, and all data and actions are transmitted through requests and responses. This simplifies scaling and caching.
