What is REST API and what HTTP methods are used?

REST API (Representational State Transfer) is an architectural style for creating web services that uses standard HTTP methods to interact with resources.

Main HTTP methods in REST:

• GET — retrieve resource data.
• POST — create a new resource.
• PUT — update an existing resource entirely.
• PATCH — partially update a resource.
• DELETE — delete a resource.

REST API relies on the concept of resources, which are identified by URLs, and operations on them are performed through these methods, ensuring simplicity and scalability.
