Digest meeting notes: Telegram

Fires the moment a webhook arrives across Telegram and PostgreSQL, pulls structured fields out of free text, then branches on the check before anything is written. Built for document search, around a "Collect Raw Text" step, in 18 documented nodes.

Digest meeting notes with PostgreSQL and Telegram 24/7. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for AI & automation. It fires on a webhook and orchestrates 18 nodes across Telegram, PostgreSQL. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. The result is a hands-off process that just works.

Key benefits

  • Keeps Telegram and PostgreSQL in step for document search, without anyone re-typing a row
  • A failed Telegram or PostgreSQL call is retried rather than dropped, at any of the 18 nodes in this document-search build
  • Branches rejoin before Telegram, so a document-search run reports once rather than 18 times
  • Every document-search run leaves an audit row behind, alongside Telegram
  • Pinned sample data ships with it — run all 18 nodes for document search before wiring Telegram

Use cases

  • Teams keeping Telegram and PostgreSQL aligned by hand for document search
  • Pushing document-search events into Telegram and PostgreSQL the moment they land, not on the next poll
  • Document search work where "Collect Raw Text" is still a manual step before Telegram
  • Document search work that only reaches Telegram when a webhook arrives, when someone remembers to start it

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Advanced level

Adds branching depth and audit logging on top of the core pattern.

  • Routing classified output into separate action branches
  • Rejoining parallel branches with Merge so the run reports once
  • Moving data between Telegram and PostgreSQL in a single run

Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.

Common questions

What exactly do I get?

The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.

How do I import it into n8n?

In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.

Do I need anything else for it to work?

You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Telegram, PostgreSQL). No coding is required.

What if it doesn't work for me?

If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.

Can I modify or resell it?

You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
