Approve requests: Gmail
Starts when someone submits the form across Gmail, PostgreSQL and Slack, 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 "Prepare Approval Packet" step, in 22 documented nodes.
Approve requests with Gmail and PostgreSQL in real time. An original, ready-to-import n8n workflow built around the 'Approval Workflow' pattern for software development & devops. It starts from a form and orchestrates 22 nodes across Gmail, HTTP / REST API, PostgreSQL. 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 Gmail and PostgreSQL in step for task routing, without anyone re-typing a row
- ✓Safe to re-run: records already in Gmail or PostgreSQL are skipped, across all 22 nodes of this task-routing build
- ✓A failed Gmail or PostgreSQL call is retried rather than dropped, at any of the 22 nodes in this task-routing build
- ✓Bad input stops the run for task routing instead of landing in Gmail
- ✓Branches rejoin before Gmail, so a task-routing run reports once rather than 22 times
Use cases
- →Teams keeping Gmail and PostgreSQL aligned by hand for task routing
- →Task routing sequences that run over days and must survive a restart before Gmail
- →Intake checked for completeness before it is stored in Gmail, for task routing
- →Task routing work where "Prepare Approval Packet" is still a manual step before Gmail
Integrations
Workflow preview (22 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (22 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 (Gmail, HTTP / REST API, PostgreSQL, Slack, …). 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.
