telegram-bot

I am using the telepot python library, I know that you can send a message when you have someone's UserID(Which is a number). I wanna know if it is possible to send a message to someone without having their UserID but only with their username(The one which starts with '@'), Also if there is a way to convert a username to a UserID. You can't send message to users using their username that is in form of @username , you can just send messages to channel usernames which your bot is administrator of it. Telegram bot api uses chat_id identifier for sending messages. If you want to achieve chat_id of

I have many telegram channels, 24\7 they send messages in the format "buy usdjpy sl 145.2 tp 167.4" "eurusd sell sl 145.2 tp 167.4" "eurusd sl 145.2 tp 167.4 SELL" or these words in some order My idea is to create app that checks every channel's message, and redirects it to my channel if it is in the above format. Does telegram api allow it? I solved a similar problem with TdLib . Their GitHub site has full C++, Java and C# examples that you can just modify. I worked on the Java example, and applied most of my changes to the UpdatesHandler.onResult method (line 353). The C++ and C# examples

When a user send an image via Telegram bot it there any way to get the image URL? or I just need to save the image somewhere? In the message array you receive you can find the key photo . There you will find multiple arrays with the following format "file_id" : "XXXX", "file_size" : 1107, "width" : 90, "height" : 51 From one of those array you need to take the file_id . You can then request the file_path with a simple get get on the url https://api.telegram.org/bot<token>/getFile?file_id=<file_id> You will receive an array that looks as following "ok" : true, "result" : { "file_id" : "XXXX",

My telegram bot is a dialog and it needs to keep the questions and the answers (like TriviaBot). What is the best (most efficient) method to do this? A database with the user id as key? There is a lot of telegram bots, but where are examples with the source code to get ideas? Your question is not really related to the telegram bot API. You are essentially asking: I have an application that has to keep an history of user interactions, how to do this (efficient)? To answer that: you could use a database and insert an entry for each conversation using an unique identifier. Since telegram has a

I'm trying to find out if a specific User is present in a supergroup, in order to keep track of those who left. For that, I'm calling the Bot API method getChatMember for each User and checking if their status is either Left or Kicked . However, I noticed that (recently?) I'm getting USER_ID_INVALID errors for many valid users that are either in the supergroup or have been in the past and then left. I also confirmed that those accounts are still active on Telegram. Here's the HTTP request I'm sending: POST https://api.telegram.org/botXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXX/getChatMember HTTP/1.1

My question is: how to join my telegram bot to a telegram public channel that I am not administrator of it, and without asking the channel's admin to add my bot to the channel? maybe the chatId of channel or thru link of channel? Thank you in advance :) edit------ I have heard that some people claim to do this join their bot to channels, and scrape data. So if Telegram does not allow it, how can they do it? can you think of any work around? Appreciate your time? Till today, only the Channel Creator can add a bot (as Administrator or Member) to the Channel, whether public or private. Even the
