I am trying to forward a message in telegram bot API in python . It shows “Bad Request: chat_id is empty” despite using same chat_id in sendMessage and works perfectly fine.

https://api.telegram.org/bot{BOT_TOKEN}/forwardMessage?chat_id={CHAT_ID}&from_chat_id={ID}&message_id={MID}

my problem is what is the message id and how can i find it?
for example chat id is like this number 123456789.

what does message id look like ?

  1. You are a bot. So, people interact with you (directly or in a group). When a message is sent to your bot, you would receive a callback that includes the message details (including the chat_id, the sender chat id, the message id, and all other details). Something like this (see message->message_id and message->from_id):

    { 
       "update_id":1111,
       "message":{ 
          "message_id":111,
          "from":{ 
             "id":1111,
             "is_bot":false,
             "first_name":"...",
             "last_name":"...",
             "username":"...",
          },
          "chat":{ 
             "id":1111,
             "first_name":"...",
             "last_name":"...",
             "username":"...",
             "type":"private"
          },
          "date": 1111,
          "text":"...."
       }
    }
    

    So, you can store those details and use them to forward that message to another chat. In each chat (unique chat id), each message has a chat id (which is usually an incremental number) and by these two identifier, you can uniquely select which message from which chat should be forwarded.

  2. Depends on where you want to access a chat_id, you can use different ways.
    if you want to send a specific message to a user or bot that you don’t know his chat_id, you can print a message from that user and access chat_id. Or simply forward a message from that user to @ShowChatIdBot and it returns you the related chat_id.
    In fact this bot extract data from your forwarded message and gives back chat_id in that message to you.
