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?!

    It's not possible with Bot API without joining the group. You should instead use an mtproto client like telethon https://docs.telethon.dev/en/latest/ to get the dialogs in your telegram and match the group name, and then get the id. – Ali Padida Dec 01 '20 at 07:07

the easiest way is to add @chatBotRaw the bot will dump raw data, and you can copy their chat_id or anything else you need,

Remember to remove the bot afterwards because it dumps raw data of every message sent/received in the group.

the simplest way i found is

  • open web-telegram in a browser
  • right click on the group name on the left menu
  • click 'inspect' button
  • you will see the group id in the attribute data-peer-id="-xxxxxxxxxx" or peer="-xxxxxxxxxx"

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

if using a bot is acceptable, you can use @username_to_id_bot - no need to add it to a group, just send username or invite link and get the id
