Capture applications: PostgreSQL, form

Starts when someone submits the form across PostgreSQL, Slack and Gmail, routes each kind of record down its own branch, then drops anything it has already handled. Built for capture forms, around a "Normalize Lead Payload" step, in 32 documented nodes.

Capture applications with PostgreSQL and Gmail. An original, ready-to-import n8n workflow built around the 'Form Intake' pattern for sales & CRM. It starts from a form and orchestrates 32 nodes across PostgreSQL, Slack, Gmail. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Your team sees the right data at the right time.

Key benefits

  • Keeps PostgreSQL and Slack in step for capture forms, without anyone re-typing a row
  • Safe to re-run: records already in PostgreSQL or Slack are skipped, across all 32 nodes of this capture-forms build
  • A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 32 nodes in this capture-forms build
  • Branches rejoin before PostgreSQL, so a capture-forms run reports once rather than 32 times
  • Every capture-forms run leaves an audit row behind, alongside PostgreSQL

Use cases

  • Teams keeping PostgreSQL and Slack aligned by hand for capture forms
  • Intake checked for completeness before it is stored in PostgreSQL, for capture forms
  • Capture forms work where "Normalize Lead Payload" is still a manual step before PostgreSQL
  • Capture forms work that only reaches PostgreSQL when a form is submitted, when someone remembers to start it

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.

  • Serving an n8n-hosted form and shaping each submission
  • Validating required fields before anything is written
  • Sending incomplete submissions to review instead of storing them

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, Slack, Gmail, 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.
