Produce social posts with Slack for captions

Runs on a schedule across Slack, Google Sheets and Notion, summarises long text with an AI chain, then drops anything it has already handled. Built for captions, around a "Pull Fresh Items (API)" step, in 31 documented nodes.

Produce social posts with Google Drive and Slack for your team. An original, ready-to-import n8n workflow built around the 'Content Generation' pattern for content creation & media. It runs on a schedule and orchestrates 31 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 captions, without anyone re-typing a row
  • Safe to re-run: records already in Slack or Google Sheets are skipped, across all 31 nodes of this captions build
  • A failed Slack or Google Sheets call is retried rather than dropped, at any of the 31 nodes in this captions build
  • Every captions run leaves an audit row behind, alongside Slack
  • The captions AI step is isolated from Slack, so models swap without touching the other 31 nodes

Use cases

  • Teams keeping Slack and Google Sheets aligned by hand for captions
  • Captions work where "Pull Fresh Items (API)" is still a manual step before Slack
  • Captions 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

Architect level

The deepest tier - sub-workflow delegation, state snapshots, and full observability.

  • Chaining a writer pass and a separate critic pass for better output
  • Converting markdown to HTML for delivery
  • Publishing as a draft so a human stays the final gate

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, Notion, …). 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.
