Digest documents: PostgreSQL + AI agent
Fires the moment a webhook arrives across PostgreSQL, Slack and Google Sheets, hands the decision to an AI agent with its own tools, then branches on the check before anything is written. Built for inbox triage, around a "Keep Valid Emails" step, in 31 documented nodes.
Digest documents with PostgreSQL and Twilio. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for marketing & advertising. It fires on a webhook and orchestrates 31 nodes across PostgreSQL, Slack, HTTP / REST API. 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 PostgreSQL and Slack in step for inbox triage, without anyone re-typing a row
- ✓Safe to re-run: records already in PostgreSQL or Slack are skipped, across all 31 nodes of this inbox-triage build
- ✓A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 31 nodes in this inbox-triage build
- ✓Branches rejoin before PostgreSQL, so a inbox-triage run reports once rather than 31 times
- ✓Every inbox-triage run leaves an audit row behind, alongside PostgreSQL
Use cases
- →Teams keeping PostgreSQL and Slack aligned by hand for inbox triage
- →Inbox triage work that needs a judgement call per item before it reaches PostgreSQL
- →Pushing inbox-triage events into PostgreSQL and Slack the moment they land, not on the next poll
- →Inbox triage work where "Keep Valid Emails" is still a manual step before PostgreSQL
Integrations

The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (31 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
Agent tools included (3)
An AI Agent is only as capable as the tools wired into it. These are read from the template's own graph — every one is a real node in the file you download.
- Lookup API Data · HTTP request
- Run Calculations · Calculator
- Search Reference Wiki · Wikipedia
This agent runs without conversation memory - each run starts from the incoming request.
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
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •Routing classified output into separate action branches
- •Rejoining parallel branches with Merge so the run reports once
- •Moving data between Google Sheets, Twilio 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, Slack, HTTP / REST API, Google Sheets, …). 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.
