Thanks alot. For some reason, I had an error when I used "_json" (I'm not sure if that was a dummy variable). When I used a key value like below, it worked well. I appreciate you showing the way. I played around with it, and found making a temp variable with the casting made the result a bit more comfortable for me.

post "/" do |env|
    entry_elements = env.params.json["entry"] as Array
    entry_elements.each do |entries|
        e = entries as Hash(String, JSON::Type)
        id = e["id"]
        time = e["time"]
        puts id, time
    end
end
