What is the role of the HTTP DELETE method and when is it used?

The HTTP DELETE method is used to delete a resource identified by a URI. Its main role is to request the server to delete the specified resource. DELETE is commonly used in REST APIs when you need to delete a record, file, or other object.

Example: if there is a resource /users/123, a DELETE request to /users/123 should delete the user with ID 123.

It is important that DELETE be idempotent — repeated DELETE requests to the same resource should not cause errors, but simply confirm that the resource has been deleted.
