Publish social posts: Slack + approval pause
Runs on a schedule across Slack, Google Sheets and PostgreSQL, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for social copy, around a "Normalize Draft Payload" step, in 21 documented nodes.
Publish social posts with PostgreSQL and Slack. An original, ready-to-import n8n workflow built around the 'Social Scheduler' pattern for content creation & media. It runs on a schedule and orchestrates 21 nodes across Slack, HTTP / REST API, 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. What used to take a morning now runs on its own.
Key benefits
- ✓Keeps Slack and Google Sheets in step for social copy, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Sheets are skipped, across all 21 nodes of this social-copy build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 21 nodes in this social-copy build
- ✓Branches rejoin before Slack, so a social-copy run reports once rather than 21 times
- ✓The pause before Slack is durable — a social-copy run survives a restart
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for social copy
- →Social copy sequences that run over days and must survive a restart before Slack
- →Social copy work where "Normalize Draft Payload" is still a manual step before Slack
- →Social copy work that only reaches Slack on a schedule, when someone remembers to start it
Integrations
Workflow preview (21 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (21 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.
- •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 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, HTTP / REST API, Google Sheets, PostgreSQL). 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.
