How to create Telegram Bot and send messages to your group

1. Create Telegram bot:

   Search for user @BotFather in Telegram app. Type /help in BotFather chat and wait for the reply. Type in the chat:

   /newbot

   or select /newbot command from Help text. Answer few setup questions:

   • Name of your bot? Write anything you like, that info will be shown in contact details. For example:

   Dead Parrot

   • Username for your bot? Must have _bot at the end, use only Latin characters, numbers or underscore sign, for example:

   deadparrot_bot

   BotFather will give you HTTP API token, remember it and keep SECRET! Example:

   1234567890:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

2. Create new Telegram group in web or mobile application and add the new bot in your group.

   https://web.telegram.org/

3. Send dummy message into your group, replace botname_bot with actual bot name:

   /my_id @botname_bot

4. Find Chat ID of your group: Type this URL in the browser - change {HTTP_API_TOKEN} to actual value

   https://api.telegram.org/bot{HTTP_API_TOKEN}/getUpdates

   From JSON result, get "chat_id" of last message in your group, including minus sign in front of it, that's Group Chat ID.

   If JSON is empty, repeat steps 3 and 4.

5. That's it, now use the bot. For all available methods, read doc from:

   https://telegram-bot-sdk.readme.io/reference

   Example for Send Text Message method:

   https://api.telegram.org/bot{HTTP_API_TOKEN}/sendMessage?chat_id={CHAT_ID}&text={MESSAGE_TEXT}

this is wrong:
/my_id @botname_bot

Unrecognized command. Say what?

wrong:From JSON result, get "chat_id" of last message in your group, including minus sign in front of it, that's Group Chat ID.

JSON does't have "chat_id"

me too, it says"{"ok":true,"result":[]}"。and /my_id@****_bot command didn't work.

It works for me fine.
"If JSON is empty, repeat steps 3 and 4."

A big note is: You have to add your bot to the group chat, and everything will work fine, at least for me

me too, it says"{"ok":true,"result":[]}"。and /my_id@****_bot command didn't work.

Ensure your bot's Group Privacy is off (to enable access to group messages).
Use BotFather to set turn off Group Privacy for your bot.
Once you do that you'll be able to see the messages.

It works for me. Must add bot to group first before send command /my_id @botname_bot and then you will got the result from http request

Thank you! It works great

This is sending the messages to the group as if they were from the admin and not from the bot, any help?

In the group, go to admins, click on the bot and untick 'remain anonymous' . Depends on the settings, you might have to use the owner account and not a admin account
