Automate Workflow Execution with Telegram Bot Command Center

This n8n workflow empowers you to remotely trigger and manage other n8n workflows using simple commands sent to a Telegram bot. It acts as a centralized command center, allowing you to execute specific workflows by name directly from your Telegram chat.

What it does

1. Listens for Telegram Commands: The workflow starts by listening for incoming messages from a configured Telegram bot.
2. Extracts Command: It processes the incoming message to identify if it's a command (e.g., /execute_workflow_name).
3. Filters Valid Commands: An If node checks if the received message matches a predefined pattern for workflow execution commands.
4. Extracts Workflow Name: A Code node extracts the specific workflow name from the command (e.g., workflow_name from /execute_workflow_name).
5. Routes to Sub-workflows: A Switch node dynamically routes the execution based on the extracted workflow name.
6. Executes Targeted Workflow: For each recognized command, an Execute Sub-workflow node is triggered, which then calls the corresponding n8n workflow by its name.
7. Confirms Execution (Implicit): Although not explicitly shown in the provided JSON, a typical implementation would include a Telegram node to send a confirmation message back to the user after a workflow is executed.

Prerequisites/Requirements

• n8n Instance: A running n8n instance where this workflow will be imported and other workflows are hosted.
• Telegram Bot: A Telegram bot token and a chat ID to listen for commands and potentially send responses.
• Target Workflows: Existing n8n workflows that you want to be able to trigger via Telegram commands. These workflows should ideally be configured to accept input from an Execute Sub-workflow node if they require specific data.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Telegram Trigger:
   • Open the "Telegram Trigger" node.
   • Add your Telegram Bot API credentials.
   • Ensure the trigger is active and listening for messages.
3. Configure Workflow Execution Logic:
   • If Node (Node 20): Adjust the condition to match the command prefix you intend to use (e.g., {{ $json.message.text.startsWith('/execute_') }}).
   • Code Node (Node 834): Modify the JavaScript code to correctly parse the workflow name from your chosen command format. For example, if your command is /execute_MyWorkflow, the code should extract MyWorkflow.
   • Switch Node (Node 112):
     • For each workflow you want to execute, add a new case to the Switch node.
     • The "Value 1" for each case should be the exact workflow name extracted by the Code node (e.g., MyWorkflow).
     • Connect each case output to an "Execute Sub-workflow" node.
   • Execute Workflow Nodes (Node 111 and others):
     • For each Execute Sub-workflow node, select the specific n8n workflow you want to trigger from the dropdown list.
     • You can pass data from the Telegram message to the sub-workflow if needed.
4. Activate the Workflow: Save and activate the main workflow.
5. Send Commands: Send commands to your Telegram bot (e.g., /execute_MyWorkflow) to trigger the corresponding n8n workflows.
