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

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
