try the following:
|(defmacrodefapihandler [handler-name params & body]`(defn~handler-name
['~passed-param](let[param-keys# (vec(map(comp symbol name
:key)~params)){:keysparam-keys#}'~passed-param];; some check~@body))) |
Sorry for brevity, I'm on my phone...

I don’t think your answer is correct. From the expaned macro

passed-param__10243__auto__] (do (println username)))) |
and following test

know how to create ISeq from: clojure.lang.Symbol (println a b)) (let
[{:keys [a b]} {:a 1 :b 2}] ; ok (println a b)) |
I think it is in let destructuring form, we can’t use dynamic var to
represent symbols

you need to use `'~passed-param` in your arg-vector, and the same
whenever you use it inside the newly defined fn.
