$("#btn").click(function() {

				Kakao.init('JavaScript 키');
			     Kakao.API.request({
			          url: '/v1/payment/ready',

이런식으로 자바스크립트에 넣어줬는데요

{name: “KakaoError”, message: “Invalid parameter keys: Authorization,method at API.request”}
message: "Invalid parameter keys: Authorization,method at API.request"
name: “KakaoError”

라는 에러가 나요 뭐가 문제인가요?
