Using the Perl API you can get it this way  first you send a message to the bot from Telegram  then issue a getUpdates and the chat id must be there      usr bin perl  use Data  Dumper  use WWW  Telegram  BotAPI   my  TOKEN    blablabla   my  api   WWW  Telegram  BotAPI- gt new       token   gt   TOKEN   or die  I can t connect    my  out    api- gt api request   getUpdates    warn Dumper  out   my  chat id    out- gt  result - gt  0 - gt  message - gt  chat - gt  id   print  chat id  chat id n     The id should be in chat id but it may depend of the result  so I also added a dump of the whole result   You can install the Perl API from https   github com Robertof perl-www-telegram-botapi  It depends on your system but I installed easily running this on my Linux server     sudo cpan WWW  Telegram  BotAPI   Hope this helps

There is a bot that echoes your chat id upon starting a conversation   Just search for  chatid echo bot and tap  start  It will echo your chat id     Another option is  getidsbot which gives you much more information  This bot also gives information about a forwarded message  from user  to user  chad ids  etc  if you forward the message to the bot

First  post a message in a chat where your bot is included  channel  group mentioning the bot  or one-to-one chat   Then  just run   curl https   api telegram org bot lt TOKEN gt  getUpdates   jq   Feel free to remove the   jq part if your dont have jq installed  it s only useful for pretty printing  You should get something like this     You can see the chat ID in the returned json object  together with the chat name and associated message

The message updates you receive via getUpdates or your webhook will contain the chat ID for the specific message  It will be contained under the message chat id key   This seems like the only way you are able to retrieve the chat ID  So if you want to write something where the bot initiates the conversation you will probably have to store the chat ID in relation to the user in some sort of key- value store like MemCache or Redis    I believe their documentation suggests something similar here  https   core telegram org bots deep-linking-example  You can use deep-linking to initiate a conversation without requiring the user to type a message first
