n8n Workflow: RSS Feed to Telegram Messenger

This n8n workflow automates the process of reading an RSS feed and sending its new items as messages to a Telegram chat. It's designed to keep you updated on your favorite feeds directly within Telegram.

What it does

This workflow performs the following steps:

1. Schedules Execution: The workflow is triggered periodically by a Cron node, ensuring that the RSS feed is checked at regular intervals.
2. Reads RSS Feed: It fetches the latest items from a configured RSS feed URL.
3. Processes Feed Items: A Function node processes the incoming RSS feed items. (Note: The specific logic within the Function node is not detailed in the provided JSON, but it typically involves formatting the data or performing initial filtering).
4. Conditional Logic: An If node evaluates each item. This is likely used to determine if an item is new or meets certain criteria before sending it to Telegram.
5. Sends Telegram Message: If an item passes the conditional check, a Telegram node sends a formatted message containing the RSS item's details to a specified Telegram chat.
6. No Operation (Fallback): If an item does not pass the conditional check, it goes to a "No Operation" node, effectively doing nothing with that item.

Prerequisites/Requirements

• n8n Instance: A running instance of n8n.
• RSS Feed URL: The URL of the RSS feed you wish to monitor.
• Telegram Bot Token: A Telegram bot token obtained from BotFather.
• Telegram Chat ID: The ID of the Telegram chat (user, group, or channel) where messages should be sent.

Setup/Usage

1. Import the Workflow:
   • Save the provided JSON content as a .json file.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the "Import from JSON" button and upload the saved file.
2. Configure Nodes:
   • Cron Node (Node ID: 7): Adjust the schedule to your preferred interval for checking the RSS feed.
   • RSS Read Node (Node ID: 37):
     • Enter the URL of the RSS feed you want to monitor.
   • Function Node (Node ID: 14):
     • Review and modify the JavaScript code within this node if you need specific data transformations or formatting before the conditional check.
   • If Node (Node ID: 20):
     • Configure the conditions based on which RSS items should be sent to Telegram. For example, you might check for a specific keyword in the title or if the item is truly new (often handled by n8n's RSS node automatically if "Read All" is false).
   • Telegram Node (Node ID: 49):
     • Credentials: Set up a new Telegram API credential using your Telegram Bot Token.
     • Chat ID: Enter the Telegram Chat ID where the messages should be sent.
     • Message: Customize the message text to include relevant RSS item details using expressions (e.g., {{ $json.title }} - {{ $json.link }}).
3. Activate the Workflow: Once configured, activate the workflow by toggling the "Active" switch in the top right corner of the workflow editor.

The workflow will now run according to the Cron schedule, fetch new RSS items, and send them to your specified Telegram chat.
