n8n-nodes-betterforms

A simple n8n trigger node that provides GET and POST endpoints for JSON-based form workflows. Built for internal use at the Leadership Institute, but anyone is welcome to use it.

What It Does

This node creates two webhook endpoints:

• GET /{path} — Returns the JSON you stored in the node (plus the POST URL as submitUrl)
• POST /{path} — Accepts a JSON body, merges it with your stored field definitions, and passes it to the workflow

Installation

Follow the n8n community nodes installation guide.

Or set the environment variable:

N8N_COMMUNITY_PACKAGES=n8n-nodes-betterforms

Credentials

Requires a BetterForms API credential with an API key. All requests must include the key via:

• x-api-key header, or
• apiKey query parameter

Usage

1. Add the BetterForms Trigger node to your workflow
2. Set the Form API Path (e.g., my-form)
3. Add your API credentials
4. Paste your form config JSON

How the POST Transform Works

The node expects your stored config to have a fields array where each field has a fieldName property:

{
  "formTitle": "Contact Us",
  "formDescription": "...",
  "successMessage": "Thanks!",
  "fields": [
    { "fieldName": "first_name", "label": "First Name", "type": "text", "required": true },
    { "fieldName": "email", "label": "Email", "type": "email", "required": true }
  ]
}

When a POST comes in with:

{ "first_name": "John", "email": "john@example.com" }

The workflow receives:

{
  "submission": {
    "first_name": "John",
    "email": "john@example.com"
  },
  "formConfig": {
    "formTitle": "Contact Us",
    "formDescription": "..."
  },
  "fields": [
    {
      "fieldName": "first_name",
      "label": "First Name",
      "type": "text",
      "required": true,
      "value": "John"
    },
    {
      "fieldName": "email",
      "label": "Email",
      "type": "email",
      "required": true,
      "value": "john@example.com"
    }
  ]
}

The fields array merges each stored field definition with the corresponding submitted value (matched by fieldName). The raw submission is also available untouched in submission.
