Approve expenses: PostgreSQL
Starts when someone submits the form across PostgreSQL, Google Sheets and Telegram, routes each kind of record down its own branch, then drops anything it has already handled. Built for approvals, around a "Stamp & Shape Task" step, in 21 documented nodes.
Approve expenses with Telegram 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 21 nodes across PostgreSQL, Google Sheets, Telegram. 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 PostgreSQL and Google Sheets in step for approvals, without anyone re-typing a row
- ✓Safe to re-run: records already in PostgreSQL or Google Sheets are skipped, across all 21 nodes of this approvals build
- ✓A failed PostgreSQL or Google Sheets call is retried rather than dropped, at any of the 21 nodes in this approvals build
- ✓Branches rejoin before PostgreSQL, so a approvals run reports once rather than 21 times
- ✓Every approvals run leaves an audit row behind, alongside PostgreSQL
Use cases
- →Teams keeping PostgreSQL and Google Sheets aligned by hand for approvals
- →Intake checked for completeness before it is stored in PostgreSQL, for approvals
- →Approvals work where "Stamp & Shape Task" is still a manual step before PostgreSQL
- →Approvals work that only reaches PostgreSQL when a form is submitted, 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.
- •Branching cleanly on approve versus decline
- •Moving data between PostgreSQL, Google Sheets and Slack in a single run
- •Splitting one run into branches and merging the results back
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 (PostgreSQL, Google Sheets, Telegram, 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.
