n8n Workflow: Automate Meeting Scheduling through Telegram

This n8n workflow provides a robust framework for automating meeting scheduling. It primarily focuses on receiving commands via a Telegram bot, processing them, and potentially interacting with other services (though the provided JSON only shows the Telegram input and email output, with placeholders for more advanced logic).

What it does

This workflow is designed to:

1. Receive Telegram Messages: It starts by listening for incoming messages or commands from a Telegram bot.
2. Process Telegram Input: It processes the received Telegram message, extracting relevant information.
3. Conditional Logic: It includes an If node, indicating that different actions might be taken based on the content of the Telegram message.
4. Send Email: In one potential branch of the workflow, it sends an email. This could be for notifications, confirmations, or to trigger further actions.
5. Respond to Webhook: It can respond to the initial webhook trigger, which is useful for acknowledging receipt of the message or providing immediate feedback.
6. HTTP Requests: It includes an HTTP Request node, suggesting potential integration with external APIs (e.g., Google Calendar, Notion CRM, or other scheduling tools).
7. Data Manipulation: Uses a Set node to manipulate or prepare data for subsequent steps.
8. Code Execution: Includes a Code node for custom JavaScript logic, allowing for highly flexible data processing or integration.
9. Manual & Scheduled Triggers: The workflow can be executed manually or on a schedule, providing flexibility for testing or periodic tasks.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Telegram Bot: A Telegram bot token and a configured Telegram credential in n8n.
• Email Account: An SMTP server configured for sending emails, or an email service credential in n8n.
• Webhook: The webhook URL generated by the Webhook trigger node.
• External APIs (Optional): If you intend to integrate with Google Calendar, Notion, or other services, you will need API keys and credentials for those respective platforms.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON content.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the "Import from JSON" button and paste the copied JSON.
2. Configure Credentials:
   • Telegram: Locate the Telegram node and configure your Telegram Bot API credential.
   • Send Email: Locate the Send Email node and configure your SMTP or email service credential.
3. Activate the Webhook:
   • The Webhook node will generate a unique URL. This URL needs to be configured as the webhook for your Telegram bot (e.g., using setWebhook API call for Telegram).
4. Customize the Logic:
   • If Node (ID: 20): Customize the conditions in the If node to define how different Telegram messages should be handled.
   • HTTP Request (ID: 19): Configure this node to interact with your desired external services (e.g., Google Calendar API to create events, Notion API to update your CRM).
   • Code Node (ID: 834): Implement custom JavaScript logic as needed for parsing complex messages, formatting data, or performing specific calculations.
   • Send Email (ID: 11): Adjust the recipient, subject, and body of the email based on your notification requirements.
   • Edit Fields (Set) (ID: 38): Modify this node to transform or set data fields as required for subsequent nodes.
5. Test the Workflow:
   • Send a message to your Telegram bot that matches one of your If node conditions.
   • Manually execute the workflow using the Manual Trigger (ID: 838) to test specific branches.
6. Activate the Workflow: Once configured and tested, activate the workflow to enable automatic processing of Telegram messages.
7. Schedule (Optional): If you have periodic tasks, configure the Schedule Trigger (ID: 839) with your desired interval.
