At first i should emphasis that this is a question about telegram GROUP NOT CHANNEL.I need to get group id to send message via telgram api.
I have review this link .
using @rawDataBot needs to add bot to group, that is not possible most of the times. CuteGram does not login (does not send login code) .so i can say none of the proposed method works.
so is there a new method -except adding a bot to the group- to get telgram group ID ?
if the answer is no, i need to know if it is possible to send message to group by using group name?!
You can get chat id throw object "chat"
You can set middleware which handle new update
Example on Node.JS: bot.on('text', ctx => console.log('Chat id is:', ctx.chat.id))
P.S. group id and chat id are same
