Build a metrics report for digests

Runs on a schedule across Slack, PostgreSQL and Google Sheets, runs the text through an AI chain, then reads the feed and keeps only what is new. Built for digests, around a "Read Source Feed" step, in 24 documented nodes.

Build a metrics report with PostgreSQL and Outlook and log the results. An original, ready-to-import n8n workflow built around the 'Scheduled Digest' pattern for software development & devops. It runs on a schedule and orchestrates 24 nodes across Slack, PostgreSQL, 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. The result is a hands-off process that just works.

Key benefits

  • Keeps Slack and PostgreSQL in step for digests, without anyone re-typing a row
  • Safe to re-run: records already in Slack or PostgreSQL are skipped, across all 24 nodes of this digests build
  • A failed Slack or PostgreSQL call is retried rather than dropped, at any of the 24 nodes in this digests build
  • The digests AI step is isolated from Slack, so models swap without touching the other 24 nodes
  • Fans the same result out to Google Sheets in the same run, for digests

Use cases

  • Teams keeping Slack and PostgreSQL aligned by hand for digests
  • Digests work where "Read Source Feed" is still a manual step before Slack
  • Digests work that only reaches Slack on a schedule, 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

Production level

Production-grade: idempotency, dead-letter handling, and reconciliation included.

  • Collecting from multiple sources and blending them into one stream
  • Summarizing and formatting a readable digest
  • Moving data between Outlook, Slack 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 (Slack, PostgreSQL, Google Sheets, HTTP / REST API, …). 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.
