https://kauth.kakao.com/oauth/authorize?response_type=code&client_id=**************&redirect_uri=http://dean-webchats.cs113.force.com/KakaoAppLoginSite&scope=talk_message,friends

hi~
Please check two things below about friends who can’t be viewed through API.

  1. Have you logged in to your site at least once?
  2. Did the friend agree to “friends” authority?

Tell me the email of a friend who is not on the list.

my team member and me we both get same response this
{“elements”:[],“total_count”:0,“after_url”:null,“result_id”:“zbnYtN-As4e_h7WDu4qz7Nju3unQ4L_NqM-m1aHEttO36I7vmfaE7Zn8o5LNrMCs85j3qN7tFQ”,“favorite_count”:0}
