Approve documents for time off

Starts when someone submits the form 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 time off, around a "Stamp & Shape Candidate" step, in 31 documented nodes.

Approve documents with Gmail and PostgreSQL. An original, ready-to-import n8n workflow built around the 'Approval Workflow' pattern for human resources & recruiting. It starts from a form and orchestrates 31 nodes across Slack, Google Sheets, HTTP / REST API. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Nothing slips through the cracks.

Key benefits

  • Keeps Slack and Google Sheets in step for time off, 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 time-off build
  • A failed Slack or Google Sheets call is retried rather than dropped, at any of the 31 nodes in this time-off build
  • Branches rejoin before Slack, so a time-off run reports once rather than 31 times
  • The pause before Slack is durable — a time-off run survives a restart

Use cases

  • Teams keeping Slack and Google Sheets aligned by hand for time off
  • Time off sequences that run over days and must survive a restart before Slack
  • Intake checked for completeness before it is stored in Slack, for time off
  • Time off work where "Stamp & Shape Candidate" is still a manual step before Slack

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.

  • Pausing a workflow on a Wait node until a human decides
  • Embedding a resume URL so approving is one click
  • Branching cleanly on approve versus decline

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, 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.
