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
Integrations
Workflow preview (24 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (24 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.
- •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.
