Distill documents: PostgreSQL, webhook

Fires the moment a webhook arrives across PostgreSQL and Telegram, classifies each item with a language model, then runs the custom logic in a Code node. Built for contracts, around a "Normalize Document Payload" step, in 16 documented nodes.

Distill documents with PostgreSQL and Telegram 24/7. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for legal & compliance. It fires on a webhook and orchestrates 16 nodes across PostgreSQL, Telegram. 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. Nothing slips through the cracks.

Key benefits

  • ✓Keeps PostgreSQL and Telegram in step for contracts, without anyone re-typing a row
  • ✓A failed PostgreSQL or Telegram call is retried rather than dropped, at any of the 16 nodes in this contracts build
  • ✓Branches rejoin before PostgreSQL, so a contracts run reports once rather than 16 times
  • ✓Pinned sample data ships with it — run all 16 nodes for contracts before wiring PostgreSQL
  • ✓16 nodes, each with a doc card explaining what it does for contracts

Use cases

  • →Teams keeping PostgreSQL and Telegram aligned by hand for contracts
  • →Pushing contracts events into PostgreSQL and Telegram the moment they land, not on the next poll
  • →Contracts work where "Normalize Document Payload" is still a manual step before PostgreSQL
  • →Contracts work that only reaches PostgreSQL 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.

  • •Classifying text with a Text Classifier and acting on the label
  • •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 (PostgreSQL, Telegram). 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.
