Auto-post social posts: Slack + approval pause

Runs on a schedule across Slack, Google Sheets and Airtable, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for newsletters, around a "Keep Valid Drafts" step, in 23 documented nodes.

Auto-post social posts with Airtable and Slack in real time. An original, ready-to-import n8n workflow built around the 'Social Scheduler' pattern for content creation & media. It runs on a schedule and orchestrates 23 nodes across Slack, Google Sheets, 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 Slack and Google Sheets in step for newsletters, without anyone re-typing a row
  • A failed Slack or Google Sheets call is retried rather than dropped, at any of the 23 nodes in this newsletters build
  • Branches rejoin before Slack, so a newsletters run reports once rather than 23 times
  • The pause before Slack is durable — a newsletters run survives a restart
  • Every newsletters run leaves an audit row behind, alongside Slack

Use cases

  • Teams keeping Slack and Google Sheets aligned by hand for newsletters
  • Newsletters sequences that run over days and must survive a restart before Slack
  • Newsletters work where "Keep Valid Drafts" is still a manual step before Slack
  • Newsletters 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.

  • Reading a content calendar and publishing only what is due
  • Marking rows published only after the post succeeds
  • Moving data between Slack, Google Sheets and Airtable 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, Google Sheets, HTTP / REST API, Airtable). 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.
