The discussion of the various patterns (create, update, delete) given in the [*Introduction & Overview*](#Introduction---Overview) section is highly relevant to the radius area. Individual Managed Objects and collections of MOs are accessed by the client using the APIs defined for each core Radius resource. Any operation that completes successfully returns a 2XX HTTP code, while unsuccessful operations return a 4XX HTTP code.
