Add friend from SDK if you know their phone number / KakaoTalkID or just send them a message without adding as friend

I want to add friend from the SDK, is it possible? I can’t seem to find any method to do so. Also, is it possible to have a full text/voice chat through the sdk with someone if you know their number or talkID?

Do you mean executing features without Kakaotalk app?
SDK does not support those features because user privacy.
Friend adding and chatting are possible on KakaoTalk app only.

@richard.jeon Thank you. I wanted to know if it was possible. Is it possible to open someone’s profile in the KakaoTalk app if I know the talkID using a url scheme? So that the user can add and chat with that person in the KakaoTalk app. I know how to open the KakaoTalk app but beyond that I don’t know.

That feature is supported for Plus friend only, not general friend.
