n8n

Trigger an n8n workflow on every submission and automate form processing across thousands of apps.

The n8n integration sends each new submission to an n8n workflow as JSON. From there you can route it to a CRM, Slack, a database, an AI step or any of the apps n8n connects to. It is a native webhook integration: you paste your n8n Production Webhook URL, with no OAuth app or API key needed. It works with n8n Cloud and self-hosted n8n.

Before you start

  • An n8n workflow that starts with a Webhook trigger node.
  • Set the node’s HTTP Method to POST.
  • Activate the workflow and copy the Production URL (it contains /webhook/). The Test URL (/webhook-test/) only listens while you click “Listen for test event” in the editor.
  • Your n8n instance must be reachable on the public internet. Private and internal addresses are rejected.

Setup

  1. 1

    Open the integration

    Open your form → Integrations, filter by Automation and click Connect on n8n.

  2. 2

    Paste the webhook URL

    Paste your n8n Production Webhook URL.

  3. 3

    Add authentication (optional)

    If the Webhook node uses authentication, pick the same type and enter its credentials (see below).

  4. 4

    Test the connection

    Click Test Connection. Formclick sends a small formclick.connection_test event and shows n8n’s response.

  5. 5

    Send a test submission

    Click Send Test Submission. It uses the form’s latest submission (or sample data) in the live format, so you can map fields in the next n8n nodes.

  6. 6

    Save

    Leave Enable for this form on and click Save & Connect. Every new submission now runs your workflow.

Authentication

Choose the option that matches the Authentication setting of your n8n Webhook node.

OptionWhat Formclick sends
NoneNo auth header. Anyone with the URL can trigger the workflow, so keep it private.
Header AuthYour header name and value, e.g. X-N8N-Key: ….
Basic AuthAuthorization: Basic … built from your username and password.
JWT / Bearer tokenAuthorization: Bearer <token>.
Your webhook URL and credentials are encrypted at rest. After saving they are only shown masked; leave a masked field as it is to keep the saved value.

Payload

Each new, non-spam submission is sent once as a POST with Content-Type: application/json and User-Agent: Formclick-n8n/1.0.

JSON
{
  "event": "submission.created",
  "submissionId": "7f6c2b8e-…",
  "formId": "0d1a4f3c-…",
  "formName": "Contact form",
  "submittedAt": "2026-11-09T10:24:31.000Z",
  "fromName": "Jane Smith",
  "fromEmail": "jane@example.com",
  "data": {
    "name": "Jane Smith",
    "email": "jane@example.com",
    "message": "Hi! Could we book a demo next week?"
  }
}

In n8n the fields are under body, for example {{ $json.body.data.email }}. Test events also include "test": true, so you can filter them out with an If node.

Manage the connection

  • Enable or disable it per form with Enable for this form.
  • Edit the URL or authentication at any time from the same screen.
  • Disconnect to stop sending submissions to n8n.
  • Failed deliveries (for example if the workflow is inactive) are retried automatically.

Troubleshooting

ResponseWhat to do
404The workflow isn’t active, or you used the Test URL. Activate the workflow and use the Production URL.
401 / 403The authentication doesn’t match the Webhook node. Check the type, header name and secret.
Redirect (3xx)Use the final webhook URL. Formclick doesn’t follow redirects.
TimeoutSet the Webhook node to respond Immediately so n8n replies before running long steps.
