This article provides a complete, practical walkthrough of the Telegram Cal Create Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Boost Efficiency with This Automated Booking-to-Newsletter Workflow Using n8n
   
   If your business regularly books meetings or consultations through tools like Cal.com, chances are you spend a considerable amount of time managing follow-ups—whether that's adding contacts to your CRM, subscribing attendees to a newsletter, or notifying your team. But what if every new meeting could trigger those tasks automatically?
   
   Enter n8n, the open-source workflow automation tool. With just a few building blocks, you can build a powerful automation that captures new meeting bookings and seamlessly integrates them into your broader business stack.
   
   Let’s take a closer look at this n8n workflow, “Meeting booked – to newsletter and CRM”, and how it works to keep your attendee data organized and your communication flow uninterrupted.
   
   How It Works: At a Glance
   
   This n8n workflow is set up to do the following when a new booking is created on Cal.com:
   
   1. Listens for new bookings via webhook.
   2. Splits all attendees in the event.
   3. Stores attendee and meeting data into a Google Sheet.
   4. Subscribes each attendee to your Beehiiv newsletter.
   5. Notifies you in a Telegram channel with the booking information.
   
   A Breakdown of the Workflow:
   
   1. Node: on New Booking (Cal.com Trigger)
   The automation kicks off with a trigger from Cal.com whenever a new booking event is detected. n8n listens for the BOOKING_CREATED event through a webhook that is configured in the Cal.com admin area.
   
   2. Node: Split Attendees
   To accommodate meetings with multiple guests, the workflow uses the Split Out node to process each attendee individually. This ensures that data for every participant is handled properly, instead of in a bundled format.
   
   3. Node: set data
   This sets up necessary constants and credentials, including:
   - Beehiiv API Key
   - Beehiiv Publication ID
   - Telegram Channel ID
   
   These values are referenced dynamically in later nodes, ensuring reusability and easy updates.
   
   4. Node: Set Attendee
   This node extracts relevant attendee-specific information—name, email, and time zone—readying it for downstream actions.
   
   5. Node: Add Users (Google Sheets)
   Using Google Sheets as a lightweight CRM or database, this node appends each attendee’s details to a spreadsheet labeled “Calendar bookings”. Data such as event title, start time, attendee name/email, time zone, and meeting length are all recorded.
   
   6. Node: Add subscriber (Beehiiv API)
   This HTTP Request node makes a POST call to the Beehiiv API, subscribing each attendee to your publication based on their email. It securely authenticates using your Beehiiv API key and references the correct publication ID.
   
   7. Node: notify in channel (Telegram Bot)
   The final step delivers a formatted Telegram message to your designated private channel. This message summarizes the booking—event name, start time, and guest details—giving you or your team an immediate update.
   
   Why It Matters
   
   This workflow is a textbook example of stacking multiple no-code integrations for business automation. By connecting Cal.com, Google Sheets, Beehiiv, and Telegram within a single workflow, it does the work of a virtual assistant—accurately and instantly.
   
   Here’s what this saves you from:
   - Manually adding meeting guests to your CRM or spreadsheets.
   - Forgetting to subscribe new users to your email list.
   - Missing timely updates about upcoming client calls.
   
   Setup Requirements
   
   Setting up this workflow is simple but requires a few components:
   
   🗓 Cal.com  
   Create an account and set up your bookings. Configure a webhook in your Cal dashboard to point to the n8n workflow URL from the “on New Booking” node.
   
   📈 Google Sheets  
   You'll need a sheet with predefined fields for booking info. This serves as your CRM or logbook.
   
   📰 Beehiiv  
   Sign up for Beehiiv and access your API key and publication ID via the account settings. You’ll need these to add subscribers programmatically.
   
   📲 Telegram  
   Create a bot that can send messages and fetch your chat ID. You'll need to add the bot to your channel and promote it to admin for notifications to work correctly.
   
   Conclusion
   
   This “Meeting booked – to newsletter and CRM” n8n template exemplifies how modern workflows can eliminate repetitive admin tasks. Whether you’re running consultations, planning sales meetings, or giving product demos, this setup ensures every attendee is informed, recorded, and engaged—without any extra clicks.
   
   Best of all, it's fully customizable. Want to integrate with a different CRM? Swap out the Google Sheets node. Prefer Slack over Telegram? Replace the notification node. n8n gives you complete control.
   
   As business and content creators gear toward automation-first operations, tools like n8n make it approachable—and dare we say—fun.
   
   🚀 Go ahead and automate smarter—not harder.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
