Summarize documents: PostgreSQL, webhook
Fires the moment a webhook arrives across PostgreSQL, Microsoft Teams and Google Sheets, scores the sentiment of every message, then drops anything it has already handled. Built for invoices, around a "Keep Valid Documents" step, in 22 documented nodes.
Summarize documents with PostgreSQL and Microsoft Teams for your team. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for legal & compliance. It fires on a webhook and orchestrates 22 nodes across PostgreSQL, Microsoft Teams, Google Sheets. 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. Your team sees the right data at the right time.
Key benefits
- ✓Keeps PostgreSQL and Microsoft Teams in step for invoices, without anyone re-typing a row
- ✓Safe to re-run: records already in PostgreSQL or Microsoft Teams are skipped, across all 22 nodes of this invoices build
- ✓A failed PostgreSQL or Microsoft Teams call is retried rather than dropped, at any of the 22 nodes in this invoices build
- ✓Branches rejoin before PostgreSQL, so a invoices run reports once rather than 22 times
- ✓Every invoices run leaves an audit row behind, alongside PostgreSQL
Use cases
- →Teams keeping PostgreSQL and Microsoft Teams aligned by hand for invoices
- →Pushing invoices events into PostgreSQL and Microsoft Teams the moment they land, not on the next poll
- →Invoices work where "Keep Valid Documents" is still a manual step before PostgreSQL
- →Invoices work that only reaches PostgreSQL when a webhook arrives, when someone remembers to start it

What's inside (22 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Production levelProduction-grade: idempotency, dead-letter handling, and reconciliation included.
- •Rejoining parallel branches with Merge so the run reports once
- •Moving data between Microsoft Teams, Google Sheets and PostgreSQL in a single run
- •Splitting one run into branches and merging the results back
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, Microsoft Teams, Google Sheets, Slack). 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.
