# REST API Reference Overview The four main HTTP methods (GET, PUT, POST, and DELETE) are mapped to CRUD operations as follows: * GET retrieves the representation of the resource at a specified URI. GET has no side effects on the server. * PUT updates a resource at a specified URI. * POST creates a new resource. The server assigns the ID for the new object and returns this ID as part of the response message. * DELETE deletes a resource at a specified URI. The API represents resources as hierarchical URIs to force the clients to use certain request sequences. ## The reports API exposes the following methods: | Action | HTTP method | Relative URI | |
