Approve expenses: Slack & Airtable
Starts when someone submits the form across Slack, Airtable and Google Sheets, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for task routing, around a "Keep Valid Tasks" step, in 23 documented nodes.
Approve expenses with Slack and Airtable hands-free. An original, ready-to-import n8n workflow built around the 'Approval Workflow' pattern for software development & devops. It starts from a form and orchestrates 23 nodes across Slack, HTTP / REST API, Airtable. 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 Airtable in step for task routing, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Airtable are skipped, across all 23 nodes of this task-routing build
- ✓A failed Slack or Airtable call is retried rather than dropped, at any of the 23 nodes in this task-routing build
- ✓Branches rejoin before Slack, so a task-routing run reports once rather than 23 times
- ✓The pause before Slack is durable — a task-routing run survives a restart
Use cases
- →Teams keeping Slack and Airtable aligned by hand for task routing
- →Task routing sequences that run over days and must survive a restart before Slack
- →Intake checked for completeness before it is stored in Slack, for task routing
- →Task routing work where "Keep Valid Tasks" is still a manual step before Slack
Integrations

What's inside (23 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.
- •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, HTTP / REST API, Airtable, Google Sheets). 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.
