Get a Telegram notification only when a word is used on a channel
You can use the Junction Bot - it allows you to follow channels and filter the messages - without joining the channel.
From the bot help message:
I can collect all posts from your favorite Telegram and Twitter channels, so you can read them like a news feed. Also you can use me inside groups and to forward one channel into another.
Steps:
- Start the bot.
- After choosing a language, send the bot the channel you're interested at - newportal.
- Send the bot a filter command, with the string that interest you:
Format: /filter @channel_name mustHave text_to_pass
(get the full/filter
command usage by sending the/filter
command to the bot).- For example, send
/filter @newportal mustHave (ru)
to get only the messages with the text(ru)
from the channel@newportal
.
- If you want, you can set the bot to forward those message to another channel - so in that case, you can create a new channel for your area.
Note: The bot help message states that it can take around 10 minutes of delay until you get the updates.
