Working with channels¶
Telegram Channels provides a way to broadcast a message to multiple users. You can manually send messages to them with your preferred Telegram client, but sometimes you would want to send them with a script, or from a bot.
With botogram you can easily do that, without even the need to run the bot.
Before you can start working with channels, you need to create a bot which will be able to send messages to your channel. If you haven’t done that already, check the bot creation chapter of this documentation.
After that you need to allow your bot to send messages to your channel. Open your favorite Telegram client, and go to the administrators’ section of your channel. From there you should add your bot, and then you’re ready.
Manage without a full bot¶
Because a bot’s initialization is quite an heavy process, you can use a
lightweight API to just interact with channels. First of all you should import
botogram, and then call the
botogram.channel() function to get a
import botogram chan = botogram.channel("@my_channel", "YOUR_API_KEY")
You need to replace
@my_channel with your channel’s public name, and
YOUR_API_KEY with the key you got before. Then you can use all the methods
Chat object with the instance you are returned.
For example, if you want to send a text message you should do:
chan = botogram.channel("@my_channel", "YOUR_API_KEY") chan.send("Hello world")
Manage from a running bot¶
If you want to control a channel from your bot, you can use all the methods
which sends messages with the channel name as the user ID. For example, if you
want to forward all the messages your bot receives to the
channel, you can do something like this:
@bot.process_message def forward_messages(chat, message): message.forward_to("@my_channel")
If instead you want to announce to the
@my_channel channel when someone
cites botogram in a chat, you can do this:
@bot.message_contains("botogram") def we_are_famous(bot, chat, message): user = "Someone" if message.sender.username is not None: user = message.sender.username bot.chat("@my_channel").send("%s mentioned botogram!" % user)
