Add a Webhook trigger

In n8n, create a workflow and add a Webhook node. Set the method to POST.

Copy the production URL, not the test one.

Add the next nodes

Google Sheets: Append Row
Slack: Send Message
Notion: Create Database Page
HTTP Request: any API you already use

Paste the URL on your form

In your Boosterpack Forms dashboard, add the n8n production URL as a webhook.

Test and activate

Click Test workflow, submit the form, map {{ $json.fields.name }} and the rest, then activate.

Why n8n. You can self-host and keep the data on your machines. Email still arrives if you keep a destination inbox on the form.

For developers

You can skip this.
