Documentation

FormNode is a multi-tenant form builder for MSPs and automation teams running n8n. These docs show you how to use every part of the platform — and how to hand the keys to an AI agent when you're ready.

Build your first form

Form builder & field types

Every field type, conditional logic, prefill, validation, and how the canvas + settings panel work together.

n8n forms

How FormNode fits in front of n8n: when Form Trigger is enough, when FormNode is the better layer, and which implementation docs to read next.

Dynamic & cascading fields

Point a dropdown at any webhook URL — n8n, ConnectWise, NinjaOne, CIPP, Hudu — and FormNode parses the response. Cascading fields refresh on parent change.

Matrix field beta

Build row-by-column review grids for access reviews, permissions, skills, RACI tables, and other workflow decisions with guardrails and agent smoke tests.

n8n dynamic dropdown forms

Configure dropdowns and multiselects to load live options from read-only n8n webhooks, including response shapes, parent context, and troubleshooting.

Approvals & decision tables

One-click approve/reject in email, decision tables for per-row decisions (firmware upgrades, license assignments), and callbacks back into n8n.

n8n webhook forms

Production webhook form guidance for n8n: payloads, idempotency, endpoint behavior, retry handling, and when custom HTML starts to strain.

n8n form approvals

Pause n8n fulfillment until FormNode captures an email or decision-table approval, then branch on the structured callback result.

Customer portal

Portal-per-organization. End users submit forms, track history, and respond to approvals; Business adds full branding and white-label controls.

Embed SDK

One script tag, three modes (inline / popup / slide-in). Auto-resizing iframe, prefill from URL or JS, postMessage event bridge.

Custom domain

Serve every portal and embed under your own domain (e.g., forms.yourcompany.com). CNAME + TXT setup with auto-issued TLS via Cloudflare for SaaS.

ConnectWise Manage pod

Surface tagged FormNode forms inside the ConnectWise company record so technicians launch onboardings, offboardings, and approvals without leaving the PSA.

n8n community node

Install @joshuanode/n8n-nodes-formnode when n8n needs authenticated access to FormNode resources beyond normal webhook submission delivery.

MCP server (overview)

Connect Claude or Codex to mcp.formnode.io. The agent builds forms, wires dynamic dropdowns, and stitches the n8n workflows behind them in plain English.

MCP setup

Step-by-step config for Claude Desktop, Claude Code, OpenAI Responses, and the OpenAI Agents SDK.

Webhook payload

Exact JSON shape FormNode posts on form submission and approval decisions. Retry behavior, retention windows, n8n integration tips.

REST API

Full OpenAPI reference for organizations, forms, submissions, and approvals. Pagination, filtering, and workspace-scoped API keys.

Changelog

Product release notes for FormNode improvements, fixes, API changes, and security hardening.

Account, team & billing

Invite teammates, manage roles, issue API keys, change plans, redeem coupons, and download invoices.
