Prerequisites

You'll need a Telegram bot to send messages to a specific user / chat. If you don't yet have a bot, create one before you copy this workflow.

You'll also need the chat ID of the user or group you're trying to message.

Finally, Telegram imposes some requirements for communicating with users / groups. For example, to send a message to a user, the user must have previously communicated with the bot.

Please consult the Telegram docs if you're encountering any issue with their API (e.g. a 400 Bad Request error).

Usage

1. Copy the workflow.
2. In the send_telegram_message step, add the chat ID where you want to deliver the message, and press Connect Account to link your Telegram account.
3. Deploy the workflow. Every time a new item shows up in your RSS feed, this workflow will send it to Slack.
