 ## Idempotent routes
 
 Idempotence is a property of a route where the final state is achieved no matter how many times the route is called, that is, calling the route once or 10 times has the same effect. This is a useful property as it means the route can be safely retried if the request fails. For RESTful and HTTP APIs, the routes using GET, PUT, and DELETE verbs are expected to be idempotent.
