Publish social posts with PostgreSQL

Runs on a schedule across PostgreSQL, Slack and Google Sheets, runs the text through an AI chain, then writes the result out as a file. Built for engagement, around a "Keep Valid Posts" step, in 22 documented nodes.

Publish social posts with PostgreSQL and WordPress in real time. An original, ready-to-import n8n workflow built around the 'Social Scheduler' pattern for marketing & advertising. It runs on a schedule and orchestrates 22 nodes across PostgreSQL, Slack, 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 Slack in step for engagement, without anyone re-typing a row
  • A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 22 nodes in this engagement build
  • Every engagement run leaves an audit row behind, alongside PostgreSQL
  • The engagement AI step is isolated from PostgreSQL, so models swap without touching the other 22 nodes
  • Fans the same result out to Google Sheets in the same run, for engagement

Use cases

  • Teams keeping PostgreSQL and Slack aligned by hand for engagement
  • Engagement work where "Keep Valid Posts" is still a manual step before PostgreSQL
  • Engagement work that only reaches PostgreSQL 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.

  • Reading a content calendar and publishing only what is due
  • Marking rows published only after the post succeeds
  • Moving data between WordPress, Google Sheets 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, 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.
