도움! HTTP notification for REST API

Hello,

I want to receive a http message when another KakaoTalk user messages me and have my bot reply back. The user may or may not be a friend. The message will either be text or a video.

How can I set up this http message? How can I reply back? My backend is using nodejs, I’m not using kakaolink or any intermediary service.

Also, what is the JSON format for such a video message? It is not in the documentation but the other types are.

Unfortunately, there is no way to receive KakaoTalk message via API.
If you want to send as service provider, Biz Message is suitable, but receiving is not available. Sending or receiving video API is not provided.
