Clojure question

I am trying to use Clojure to connect to Alpaca. Right now I am stuck trying to mimic the Postman tutorial.

This is my code:
(client/get "" {:headers {:APCA-API-KEY-ID "...", :APCA-API-SECRET-KEY "..."}})
the response I get is
"{\"code\":40110000,\"message\":\"access key verification failed : access key not found (Code = 40110000)\"}",
I registered today if that makes any difference.

I solved it. I didn’t register properly with Alpaca is all.

Please explain what was necessary so others that have the issue find a potential fix.
