How to know if user has seen a message sent by my bot in Telegram?

Question

I'm developing a Telegram bot, and I want to know whether a user, that has started a private chat with my bot, has seen a certain message sent by bot, and to know when has he seen it.
Is it possible to do so?
Thank you very much.

Answer 1

That's currently not possible.

Answer 2

I'm using this solution.

1. Create a channel specially for your bot
2. Let your robot send message from this channel to users, you can use forward method.
3. Now you can see how many users have seen your message

Answer 3

Telegram Bot API has limit functionality. There is absolutely no way to get message view count at the time of this comment.

Usually TDLib can be used instead of Telegram Bot. It is Telegram client library. You can use it directly or make it as services for BOT to call.

For example. use TdApi.GetMessage to get the message, and the returned message has field of interactionInfo which contains forwardCount or viewCount.
