Transforming keys of a map in Clojure

I'm working with a REST API that represents an account with the following JSON: ``` { "userName": "foo", "password": "bar", "emailId": "baz" } ``` I have a Clojure function to create an account that can be called like this: ``` (create-account :username "foo" :password "bar" :email "baz") ``` What I want to do is map the nice keys that `create-account` takes to the funky ones that the REST API expects. My current solution is this: ``` (def clj->rest {:username :userName :email :emailId}) (apply hash-map (flatten (map (fn [[k v]] [(or (clj->rest k) k) v]) args))) ;; args is the arguments to create-account, as above ``` Is there a more idiomatic way to accomplish this?
