n8n Workflow: Telegram Bot Command for GitHub Actions

This n8n workflow demonstrates a basic setup for triggering actions based on a Telegram bot command. It listens for incoming messages on Telegram, and if a specific command is detected, it passes the message content to a GitHub node.

What it does

This workflow automates the following steps:

1. Listens for Telegram Messages: It acts as a listener for messages sent to a configured Telegram bot.
2. Processes Incoming Data: Any message received by the Telegram bot is captured.
3. Conditional Logic: The workflow includes an "If" node, which suggests it's designed to evaluate the incoming Telegram message for a specific condition (e.g., a particular command).
4. Data Transformation (Optional): An "Edit Fields (Set)" node is present, indicating that the workflow might modify or extract specific data from the Telegram message before further processing.
5. GitHub Interaction: If the condition in the "If" node is met, the workflow is intended to interact with GitHub, likely to trigger a GitHub Action, create an issue, or perform another GitHub-related task.
6. No Operation (Fallback): A "No Operation, do nothing" node serves as a fallback path, presumably for when the condition in the "If" node is not met.

Prerequisites/Requirements

To use this workflow, you will need:

• Telegram Bot: A Telegram bot token and the bot added to the chat where commands will be sent.
• n8n Telegram Credential: Configured n8n credential for your Telegram bot.
• GitHub Account: Access to a GitHub repository where actions or other operations will be performed.
• n8n GitHub Credential: Configured n8n credential for your GitHub account.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Telegram Trigger:
   • Select your Telegram Bot API credential in the "Telegram Trigger" node.
   • Set up the "Allowed Updates" and "Message Type" as per your requirements (e.g., text messages).
3. Configure the If Node:
   • Edit the "If" node to define the condition for your Telegram bot command. For example, you might check if {{ $json.message.text }} contains a specific string like /release.
4. Configure Edit Fields (Set) Node:
   • Modify this node to extract or format any necessary data from the Telegram message that you want to pass to GitHub. For instance, you might extract a version number or a release message.
5. Configure GitHub Node:
   • Select your GitHub credential.
   • Configure the GitHub node to perform the desired action (e.g., "Repository Dispatch" to trigger a GitHub Action, "Create Release", etc.) using the data prepared in the "Edit Fields (Set)" node.
6. Activate the Workflow: Save and activate the workflow.

Once activated, your Telegram bot will listen for messages. When a message matching your defined condition (e.g., a specific command) is received, the workflow will execute the configured GitHub action.
